  • Selective Hydrogenation of Acetylene over Palladium Catalysts Based on
           Aluminosilicate Nanotubes

    • Free pre-print version: Loading...

      Abstract: Silanized aluminosilicate halloysite nanotubes were investigated as a support for Pd–Ag catalysts. The samples were characterized by low-temperature nitrogen adsorption, ammonia temperature-programmed desorption, and transmission electron microscopy, and tested in selective hydrogenation of acetylene. The Pd–Ag/halloysite catalysts synthesized from [Pd(NH3)4]Cl2 as a palladium precursor proved to be the most selective towards ethylene: the selectivity reached about 85% at 10–55% acetylene conversion.

  • Hydrodechlorination of 1,4-Dichlorobenzene over Unsupported Sulfide
           Catalysts

    • Free pre-print version: Loading...

      Abstract: A number of unsupported NiMo, CoMo, and NiW sulfide catalysts synthesized in situ from oil-soluble precursors were investigated in hydrodechlorination of 1,4-dichlorobenzene. The unsupported NiW and NiMo sulfide catalysts exhibited the highest activity; after seven hours on stream in a batch-type reactor at 320°C and 4 MPa hydrogen, both catalysts achieved 99% conversion of 1,4-dichlorobenzene, and the selectivity towards chlorine-free products reached 99 and 78%, respectively. Under identical conditions, the CoMo(S) catalyst provided lower conversion (88%) with 100% selectivity. In contrast, under similar conditions a commercial NiW(S) catalyst exhibited comparable conversion with lower selectivity (95%), and a commercial NiMo(S) catalyst provided 82% conversion and 53% selectivity. The activity of the synthesized unsupported catalysts remained unchanged even after five cycles of reuse, whereas the commercial catalysts deactivated due to the destruction of the support when interacting with hydrogen chloride. The study revealed the optimum hydrodechlorination conditions in the presence of unsupported sulfide catalysts and identified the effects of the promoter to active metal ratio on conversion and selectivity. For the NiW(S) catalysts, it was found using X-ray photoelectron spectroscopy that tungsten was mostly present as WOxSy in the first cycle and WO3 in the fifth cycle, and nickel occurred in the NiS, Ni–W–S, and Ni2+ forms. Transmission electron microscopy showed the formation of fine-dispersed particles of NiS and WS2.

  • Structure and Chemical Features of Products of Polyethylene and Petroleum
           Tar Hydroconversion

    • Free pre-print version: Loading...

      Abstract: The relationships in formation of the hydrocarbon composition of the hydrogenizate fraction in polyethylene and petroleum tar hydroconversion were studied. The catalytic hydroconversion of tar, polyethylene, and their blend was performed at 450°С and a pressure of 7 MPa in the presence of nanosized MoS2 catalyst. A synergistic effect in hydroconversion of a polyethylene–tar blend was revealed. The composition of hydrogenizate fractions was substantiated using the results of quantum-chemical and thermodynamic calculations of structures simulating the hydroconversion products of tar, polyethylene, and their blend. Procedures were suggested for calculating the structural parameters (total number of atoms, total number of all types (single, double, triple) of chemical bonds, structure unsaturation parameter) of fractions of liquid hydroconversion products, based on the elemental composition data. A classifier systematizing the hydrogenizate fraction components and allowing prediction of some physical properties of the fractions (density, solubility) from the degree of structure unsaturation was constructed.

  • Properties of In Situ Obtained NiWS Nanocatalysts in Hydrogenation of
           Bicyclic Aromatics

    • Free pre-print version: Loading...

      Abstract: A NiWS sulfide catalyst was generated in situ by decomposition of [(Met)3S]2Ni(WS4)2 as a precursor, and characterized by transmission electron microscopy and X-ray photoelectron spectroscopy. The obtained catalyst is active in hydrogenation of bicyclic aromatics. Heating and extending the reaction time were found to enhance the substrate conversion; the catalyst activity was further increased by adding a sulfiding agent. At a substrate/W molar ratio of 250/1, the conversion was 25% without the addition of the sulfiding agent. With the sulfiding agent it reached 65%.

  • Application of In Situ ATR-FTIR Sресtrоsсору for Determination of
           Wax Aрреаrаnсе Tеmреrаturе at High-Prеssurе СО2 Conditions
           

    • Free pre-print version: Loading...

      Abstract: Attenuated total reflection Fourier-transform infrared (ATR-FTIR) spectroscopy was for the first time employed to investigate in situ paraffin crystallization under CO2 high-pressure and to evaluate a critical parameter—wax appearance temperature (WAT). To determine the WAT under pressure, conventional calculation methods based on changes in the band of rocking vibrations of CH2 group were used. Using model 10 wt % paraffin solutions in n-dodecane, temperature effects were investigated under CO2 pressures of 10, 20, 30, and 40 atm. It was experimentally confirmed that an increase in the CO2 pressure reduces the WAT. Furthermore, the plot of peak intensity of the spectral band attributed to dissolved CO2 as a function of temperature showed a maximum that can serve as an additional WAT indicator. This enhances the measurement accuracy and the reliability of WAT evaluation.

  • In Situ Generated Dispersed Catalysts Based on Molybdenum and Tungsten
           Phosphides in Hydroprocessing of Guaiacol

    • Free pre-print version: Loading...

      Abstract: Amorphous catalysts based on molybdenum and tungsten phosphides were prepared in situ from oil-soluble precursors such as triphenylphosphine and carbonyls of the corresponding metals during hydrodeoxygenation of guaiacol. These catalysts were characterized by powder X-ray diffraction, X-ray photoelectron spectroscopy, extended X-ray absorption fine structure spectroscopy, and transmission electron microscopy. After 6 h of reaction at 320–380°C and an initial hydrogen pressure of 5 MPa, the guaiacol conversion amounted to 89–91% in the presence of the molybdenum phosphide catalyst and 80–86% with tungsten phosphide. The selectivity towards phenol as the main reaction product reached as high as 80% in the presence of molybdenum phosphide (360°C, 6 h) and 78% in the tungsten phosphide case (340°C, 1 h). In the presence of both catalytic systems, the reaction products also contained anisole, cresols, and toluene.

           Ruthenium-Doped Cadmium Sulfide Supported on SBA-15 in Photocatalytic
           Hydrogen Generation

    • Free pre-print version: Loading...

      Abstract: Photocatalysts based on SBA-15 mesoporous silicate with supported ruthenium-doped cadmium sulfide particles of up to 10 nm size were synthesized and studied. The systems prepared are stable and exhibit high activity in photocatalytic hydrogen generation from aqueous electrolyte solutions. The apparent quantum efficiency of the reaction for the most active material (active phase 0.2Ru20CdS) was 10.9%. The catalyst showed high stability in eight reaction cycles.

  • Optimization of 4,4-Dimethyl-1,3-dioxane Synthesis Conditions in
           Condensation of tert-Butanol with Formaldehyde over Zeolites A and X

    • Free pre-print version: Loading...

      Abstract: The paper describes linear optimization of process conditions for condensation of tert-butanol with aqueous formaldehyde in the presence of synthetic zeolites (CA-Y, NaA-Y, CaA-Y, NaX, and CaX) and phosphoric acid as catalysts. The process was carried out in an autoclave at 100–150°C, 0.5–0.6 MPa, and a stirring speed of 60 rpm. The selectivity towards 4,4-dimethyl-1,3-dioxane (DMD) as a target product in the Prins reaction involving tert-butanol was investigated as a function of optimization parameters such as reaction time, temperature, reactant ratio, phosphoric acid content, and synthetic zeolite type. For each “parameter vs. DMD selectivity” function, an extremum point corresponding to the optimal parameter value was found. In the presence of NaA-Y, the DMD selectivity reached 98%.

  • Experimental and Kinetic Modeling of n-Heptane Hydroconversion over
           Mesoporous Pt/MSU Catalyst. Effect of Site Activity and Residence Time

    • Free pre-print version: Loading...

      Abstract: A zeolite-based mesostructured (MSU) molecular sieve material was synthesized, characterized, and used in the preparation of Pt (0.6 and 1 wt %) supported catalysts for hydroconversion of n-heptane under the experimental conditions of 300–450°C and 760 mmHg. Samples were characterized by X-ray diffraction (XRD), N2 adsorption-desorption isotherm, and NH3-TPD (temperature-programmed deposition) techniques. The activity test shows that catalysts have good activity and selectivity for isomerization reaction. Also, increasing metal sites, selectivity tends to the production of aromatization reaction in the heterogeneous catalytic process. Based on experimental results, a kinetic model of this reaction was carried out. Based on other publications and combining the examined features, a network of the reaction was proposed. It can be claimed that the results of converging the feed from the kinetic model are in good agreement with the experimental results. Some of the superiorities of this model compared to other models are the determination of kinetics parameters, source of isomers, aromatic, and cracked products distinctly with emphasis on the effect of site activity and residence time over metal-acid sites.

  • Research on Nano Inhibition and Plugging Potassium Amine Polysulfonate
           Drilling Fluid System to Prevent Wellbore Instability in Deep Complex
           Formations

    • Free pre-print version: Loading...

      Abstract: The wellbore instability caused by complex strata is a common problem in drilling engineering, which not only causes economic losses, but also reduces the field drilling efficiency. This paper has taken Block A of Junggar Basin as an example to explore the causes of wellbore instability in complex strata and establish corresponding solutions. Studying the core samples in this area and analyzing the logging data, it is concluded that the micro-fractures developed in the rock layer of the block provide natural channels for the entry of filtrate. At the same time, the water-sensitive clay minerals in the formation have hydration after encountering the filtrate. By optimizing the composition, the corresponding nano-strong inhibition and strong plugging potassium amine polysulfonate drilling fluid system (NPAP-2) was established. The overall use of asphalt anti-sloughing agent, nano-and micro-scale cracks (gaps) for physical plugging, wetting inversion control surface water absorption, chemical inhibition of internal hydration. The performance test shows that the HTHP water loss of the drilling fluid system is less than 10 mL, the recovery rate of rock sample is more than 86%, the viscosity is reasonable, the expansion rate is more than 89%, and the filtration loss is reduced from 8.0 to 5.0 mL. The results show that the NPAP-2 can reduce the liquid activity to enhance the inhibition, effectively improve the settlement stability of drilling fluid, reduce the filtration and ensure the wellbore stability.

  • Influence of the Promoter Deposition Conditions on the Catalytic
           Properties of Ruthenium–Cobalt Systems in the Fischer–Tropsch
           Synthesis

    • Free pre-print version: Loading...

      Abstract: The composition, structure, catalytic activity, and selectivity of alumina-supported cobalt catalysts promoted with ruthenium deposited by different methods were studied. The systems with bimetallic RuCo nanoparticles were studied in the Fischer–Tropsch synthesis. The catalyst containing 13.38 wt % Co and 0.11 wt % Ru, prepared by microwave-assisted promoter deposition, exhibits higher selectivity with respect to liquid products (yield of С5+ hydrocarbons 82.1%) and higher chain growth factor (α = 0.863) compared to the systems of similar composition (13.51 wt % Co, 0.13 wt % Ru), prepared using ultrasonic treatment. Microwave irradiation leads to the homogeneous distribution of bimetallic particles on the inner and outer surfaces of support pores, which results in increased yield of high-molecular-mass products in the Fischer–Tropsch process.

  • Effect of Rock on Aquathermolysis Reactions at Laboratory Scale (A Review)

    • Free pre-print version: Loading...

      Abstract: Enhanced recovery methods are an important stage in the oilfield development and exploitation program. They allow generating an increase in production related to the decrease of the remaining oil in the reservoir, which was not possible to remove in previous production schemes. Among them, steam injection is one of the methods used, whose main objective is to reduce the viscosity of the crude oil. In the literature there are researches where is evident an interaction between the steam and the crude oil in the reservoir, giving way to the occurrence of chemical reactions called Aquathermolysis. This transformation is a chemical result that occurs at temperatures between 200 to 325°C typical for steam injection. However, the investigations have been focused more on the fluid-fluid interaction than the rock-fluid synergy. The present work aims to better understand the synergy generated in the fluid-rock interaction through a systematic review of the research found in the literature associated with the use of rock fragments, minerals, or porous media in steam injection conditions. For analyzing the data, a descriptive bibliometric study was made with the selected studies where a rock sample was used. As a result, the addition of the mineral and rocks over the reactions generates a catalytic effect observed in the physical and chemical crude oil properties changes. This additional effect is generated for the presence of some minerals in the rock sample and this behavior could change according to its composition. Also, the gas production and its variation under different operational parameters are evidence of rock presence benefits over the process.

  • Activity of In situ Obtained NiWS Catalysts in Hydrodeoxygenation: Effect
           of Water Addition

    • Free pre-print version: Loading...

      Abstract: Unsupported NiWS catalysts formed in situ by thermal decomposition of the synthesized sulfonium thiosalt were studied in hydrodeoxygenation of diphenyl ether. The influence of the reaction temperature and time, H2 pressure, and gravimetric water content of the system on the catalyst activity and reaction product composition was studied. The diphenyl ether conversion reaches 100% already in 2 h after the start of the process and at an H2 pressure of 1 MPa. The catalysts obtained were characterized by high-resolution transmission electron microscopy and X-ray photoelectron spectroscopy. The water addition to the system does not noticeably influence the activity of the formed catalysts but leads to changes in the morphology of sulfide particles and phase composition of the surface layer of the catalysts.

  • Effects of Binder Type on Physicochemical and Strength Properties of ZSM-5
           Catalyst Supports for Xylene Isomerization

    • Free pre-print version: Loading...

      Abstract: A number of catalyst supports for hydroisomerization of C8 aromatics were synthesized using various binders such as alumina, silica (pyrogenic, colloidal, and ordered mesoporous MCM-41), and natural aluminosilicate halloysite nanotubes (HNTs). These supports were examined by relevant physicochemical analytical methods, including transmission electron microscopy, low-temperature nitrogen adsorption/desorption, ammonia temperature-programmed desorption, and energy dispersive X-ray fluorescence spectrometry. The mechanical crushing strength of the samples was determined. The support synthesized with HNTs as a binder exhibited a significant percentage of mesopores, moderate acidity, and relatively high mechanical strength.

  • Alkylation of Guaiacol with Alcohols on Porous Aromatic Frameworks
           Modified with Sulfo Groups

    • Free pre-print version: Loading...

      Abstract: This paper reports on an investigation of the alkylation of guaiacol with isopropanol and cyclohexanol over sulfonated porous aromatic frameworks, designated as PAF-20–SO3H and PAF-30–SO3H. The catalyst structures were characterized by infrared spectroscopy and low-temperature nitrogen adsorption; the elemental composition and acidity were measured by CHNS analysis and potentiometric titration. The alkylate composition was found to be sensitive to the reaction conditions and catalyst structure. PAF-30–SO3H was demonstrated to achieve 58% guaiacol conversion over 2 h of alkylation with cyclohexanol at 250°C and 3 MPa, with the reaction products mostly consisting of benzene ring monoalkylation products. In guaiacol alkylation with isopropanol, the product composition depends on the catalyst structure: after 6 h of reaction, the benzene ring monoalkylation products prevailed (accounting for up to 23% of the total product) in the case of PAF-20–SO3H, whereas PAF-30–SO3H promoted the yield of a mixture of monoalkylates (up to 34%) and dialkylates (up to 35%).

  • Effects of Tar Hydrocracking on Subsequent Carbonization

    • Free pre-print version: Loading...

      Abstract: The study investigated thermal carbonization of oil tar in comparison with tar carbonization over a Ni/Sibunit catalyst at 450–600°C. The addition of Ni/Sibunit to the tar slightly enhanced the yield of coke. However, various sulfur compounds released during tar carbonization interact with metallic nickel to form nickel sulfide, thus rapidly deactivating the catalyst in carbonization that occurs by the carbide-cycle mechanism. To suppress the deactivation of 8%Ni/Sibunit under the impact of sulfur compounds, we hydrocracked the tar sample prior to feeding it to the carbonization. The tar hydrocracking was carried out in a flow-type reactor with a fixed bed of sulfided Ni–Mo/Al2O3 catalyst in a hydrogen atmosphere (the other reaction conditions included 16.0 MPa, 420°C, LHSV 0.5 h–1, and a hydrogen/feed ratio of 2000 v/v). The hydrocracking appreciably reduced the content of sulfur and nitrogen in the liquid product. In the presence of 8%Ni/Sibunit, the carbonization of the liquid tar hydrocracking product enhanced the yield of coke compared to that in the thermal carbonization. The catalytic carbonization was found to change the carbon morphology. Specifically, in the 8%Ni/Sibunit addition case, carbon nanofibers 15–40 nm in diameter were detected. In addition to the carbon nanofibers, the formation of amorphous carbon sheets was observed.
