  • Mango Seed Kernel Agronomical Bio-Waste for Ecofriendly Cotton Dyeing:
           Optimization of Dyeing Period and Temperature

    • Abstract: Publication date:  Jul 2018
      Source:Chemical and Materials Engineering  Volume  6  Number  2  Manindra Nath Roy   M. Tauhidul Islam   Md. Saddam Hossain Khan   Kallol Sarker   and Md. Abdullah Al Mamun   Typical synthetic colorant and their application processes include various negative eco-toxicological effect and human health risk. Intend to depose the impediments of synthetic dyeing herein mango seed kernel agronomical bio-waste was employed for sustainable dyeing of cotton fabric. 100% cotton knitted single jersey commercially scoured-bleached fabric having areal density of 160 grams per square meter was used for this study. Natural dye was extracted by alkali extraction method from raw seed kernel of Mangifera indica. Optimum dyeing temperature and duration were quantified. Colorimetric appearance of the dyed samples for different dyeing condition were evaluate by using CIE L*a*b* color space in terms of color co-ordinates, color strength (K/S), brightness index (BI) and degree of color levelness values. Dye fiber bonding stability of the dyed fabric was evaluated in terms of colorfastness to wash, water, perspiration, rubbing and light. Overall the colorfastness values were recorded as 4-5 except light fastness. Excellent colorimetric appearance and serviceability indicates future green coloration of cotton fabric through mango seed kernel as well as decent agronomical bio-waste management.

  • Removal of Dyes from the Environment by Adsorption Process

    • Abstract: Publication date:  Jul 2018
      Source:Chemical and Materials Engineering  Volume  6  Number  2  Massoud Kaykhaii   Mojtaba Sasani   and Sahar Marghzari   Organic dyes are considered as serious water pollutants. There are several ways for removal of these compounds from environment, which are mainly based on biological, chemical, and physical methods. In this paper, we first classify the common organic dyes which are in use in today's industry; then, methods of their elimination from environmental water and wastewater will be discussed very briefly, with an emphasize on adsorption techniques. At the end, some modern advanced adsorbents are presented.

  • Model Catalyst Performance and Efficiency during the Hydro-treatment of
           Heavy Oil Residuum

    • Abstract: Publication date:  Feb 2018
      Source:Chemical and Materials Engineering  Volume  6  Number  1  Jamal Mohammad Amous   Fixed bed tubular plug flow reactor is used to investigate model catalysts performance during the hydrodesulphurization of Heavy Arabian Oil atmospheric residuum. The effects of temperature (300-380℃), pressure (30-80 atm) and particle size with characteristic lengths (Lpo = 0.0059cm), Lp1 = 0.0327cm) on the rate of the Hydrodesulphurization reaction are investigated. Supported Co-Mo/ γ-AL2O3 catalysts, CAT-1 with Co= 3wt.% and Mo= 10.6wt.% and 0.5wt.% MS 13X and CAT-2 with the same composition but without the addition of MS 13X loadings were prepared using the double impregnation method. All prepared catalysts were characterized for their porous structure and composition. A Kinetic equation was developed for pulverized CAT-1 particles, RHDS= 9.9696*1010 exp (-17058/T) * PH2 *CS2.2 / (1+0.00802 * PH2). Effectiveness factors and effective diffusivity coefficients were estimated for both catalyst particle sizes. CAT-1 catalyst sample showing slightly higher activity lost approximately 20% of its initial activity after 450 hours of operation compared to 11% lost for CAT-2 sample. The presence of MS 13X in CAT-1 is accompanied with lighter HC products (C1-C4 up to 210℃) giving rise to more hydrocracking orientations especially at high temperatures with higher API degrees of the treated products.

  • An Eco-friendly Approach of Cotton Fabric Dyeing with Natural Dye
           Extracted from Bixa orellana Seeds Employing Different Metallic Mordants

    • Abstract: Publication date:  Feb 2018
      Source:Chemical and Materials Engineering  Volume  6  Number  1  Nasim-Uz-Zaman   Md. Luthfar Rahman Liman   Abdul Kader   Md. Abdullah Al Mamun   Bappi Sarker   Rafiul Islam   and Israt Parveen   The aim of this project work is to study the application of Bixa orellana seed for dyeing of cotton knitted fabric. To satisfy the future demand for an eco-friendly as well as sustainable dyeing of cotton fabric numeric exploration had been performed in this work. Natural dye was extracted by normal water extraction method with caustic soda from raw seed of Bixa orellana. In this experiment commercially scoured-bleached 100% cotton knitted single jersey structure fabric with an areal density of 140 grams per square meter is used. Pre-mordanting action of cotton fabric samples were carried out using various metallic salts. Samples were dyed using by Glauber Salt + hot wash with Standard Soap, without Glauber Salt + hot wash, Glauber Salt + without hot wash and without Glauber Salt + without hot wash. Color strength of the dyed samples for different dyeing condition was assessed by means of K/S value. To intensify the color strength various mordanting agents were used. Effect of mordanting agents had evaluated by means of K/S value. Best color strength was yield for the samples dyed with Bixa orellana which were mordanted with CuSO4. Impact of electrolyte on color strength had also investigated by means of K/S value. Color fastness of the selected dyed samples to water, washing, perspiration and rubbing were evaluated. Impact of mordanting agents, hot wash and electrolyte were intensively evaluated. In all cases mordanted samples with CuSO4 exhibit best result. This result adumbrates developing a sustainable technology for a cabalistic utilization of Bixa orellana seed for coloration of cotton knitted fabric. The exquisite assessment of all tested properties of colored samples evolves this technology can be commercially implemented by considering few limitations.
