Review on: Heterogeneous Solid Base Catalyst Production from Waste Animal Bone as Transesterification of Jatropha Oil
Abstract: Biodiesel is produce mainly by transesterification, reacting vegetable oils or animal fats with monohydric alcohol in presence of a catalyst. The transesterification reaction is affected by various parameters. One of this parameter is catalyst type. Generally, catalysts used in transesterification reaction can be divided into three categories: homogenous, heterogeneous and enzymes. Heterogeneous catalysts offer numerous advantages over homogeneous catalysts as it can easily be separated from reaction mixture and can …

Review on Drying of Tea Leaf during Manufacturing Process.
Abstract: India is the world's largest tea producer, and Assam contributes about 55 per cent of India's total production making it the largest tea growing area in the world. Tea production started in the early 1800s, during the British period. Maniram Dewan was Assam's first tea-maker. In the first two decades (1840–1860), the cultivation and production of Assam tea was monopolized by the Assam Company, which worked in Upper Assam districts …

Modelling and Evaluation of Kinetics of Methane Chlorination using Matlab Techniques
Abstract: The chlorination of methane follows series-consecutive reaction mechanism to yield the chloromethanes products. The equation of reaction comprised of four consecutive step chemical reaction equations. The kinetics model for chlorination of methane into monochloromethane, dichloromethane, trichloromethane and tetrachloromethane was developed from the chemical reaction equations. In the elementary rate equation, the concentration of chlorine was assumed to be in excess, reducing the model to first order kinetics. The developed model …
