Discharge of untreated industrial and other effluents have made the water unconsumable. Present work is an attempt to fabricate new stimuli responsive adsorbent based on natural exudate gum sterculia, an indigenous natural gum for uptake of a cationic dye malachite green. Magnetic field responsive terculia gum–graft-poly(n-isopropylacrylamide-co-acrylamide) nanocomposite have been prepared and assessed it as adsorbents for enrichment of malachite green from aqueous solution. The nanocomposite is characterized by FTIR, TG-DTA, VSM and swelling studies. The VSM results have shown is superparamagnetic behaviour of nanocomposite with saturation magnetization of 1.5065 emu/g. The adsorption follows Temkin isotherm and results indicate maximum adsorption capacity of 19.977 (98.78%) malachite green. The desorption studies demonstrates excellent recovery ability of nanocomposite. The adsorption study confirms the prospective applications of polysaccharide based magnetic hydrogel for the fruitful and greener disposal of cationic dyes.","PeriodicalId":13388,"journal":{"name":"Indian Journal of Chemical Technology","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135446271","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Catalytic transesterification and non-catalytic supercritical mode of transesterification are simulated with experimental results and compared to determine the efficient mode of transesterification under different initial feedstock raw material conditions. It is found that the supercritical method (280℃; 276.4 atm; 42:1 for alcohol and oil ratio) is efficient in terms of cost and product quality for the feedstocks with high Free Fatty Acid (FFA) content. For feedstocks with a negligible amount of FFA, alkali-catalyzed homogeneous transesterification (60-65℃; 4atm; 6:1- alcohol: oil ratio) is efficient in terms of product quality and yield although the cost is similar to that of the supercritical mode of transesterification. Pre-treatment steps like simple esterification and glycerolysis for high FFA-contained feedstocks are studied using the ASPEN simulation to understand better the overall process by which the pre-treatment is carried out. Finally, the combustion characteristics of the biodiesel blend along with n-heptane (a surrogate for Petro-diesel) are studied using the Python scripted Cantera combustion chamber and it is found that the amount of soot and carbon monoxide emission is very less indicating complete and efficient combustion. This simulation study is carried out with the help of DWSIM simulation software.","PeriodicalId":13388,"journal":{"name":"Indian Journal of Chemical Technology","volume":"269 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135444883","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effect of an inclined magnetic field on mixed convection in a square cavity through a porous medium has been numerically investigated in the current paper. Various levels of thermal conductivity have been maintained on each wall throughout the system. Additionally, the Cattaneo-Christov heat flow model is influenced in the energy equation. The conservation equations for primary, secondary, and mass momentum, energy, and nanoparticles with wall boundary conditions are dimensionless and coupled to proper scaling transformations. To address the dimensionless nonlinear coupled boundary value problem, a finite-difference computing methodology known as the Harlow-Welch Marker and Cell (MAC) method is used. The fundamental goal of this research is to look at the rheological behaviour of nanoparticles as base fluids in the aforementioned effects. The influence of factors on the physical framework such as Richardson number (Ri), Hartmann number (Ha), Darcy number (Da), Reynolds number (Re), and Prandtl number (Pr) is investigated graphically. The MATLAB software is used to obtain streamlined and isothermal contours. The findings indicate an enhancement in the average Nusselt number with an increase in the parameters. Furthermore, the presence of nanoparticles raises the average Nusselt number for low values of the Reynolds number. The system is analyzed with three convection stages of Richardson number, and it is also found that for mixed convection, the system holds better results. The obtained outcomes are compared with well-known existing findings to validate the present work.","PeriodicalId":13388,"journal":{"name":"Indian Journal of Chemical Technology","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135446280","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
