• Literature review on the esterification/transesterification catalytic processes in biodiesel production. Highlighting use of Fats, Oils, and Greases (FOGs) from wastewater. Reduction high Free Fatty Acid (FFA) content FOGs by esterification to methyl/ethyl ester. Evaluation reaction conditions, such as temperature, time, types catalyst, alcohol. A promising solution for near future is substit...
In this study, the solution combustion method as a simple, fast, and cost-effective method was utilizedfor the fabrication of spinel nickel aluminate as a stable material to use in the esterification reaction.The effect of fuel amount (urea) as an important parameter of the solution combustion method on thestructure, properties, and performance of the sample was evaluated. The...
A Taguchi robust design method with an L₉ orthogonal array was implemented to optimize experimental conditions for the biosynthesis of triethanolamine (TEA)-based esterquat cationic surfactants using an enzymatic reaction method. The esterification reaction conversion% was considered as the response. Enzyme amount, reaction time, reaction temperature and molar ratio of substrates, [oleic acid: ...
A new procedure for the preparation of methyl esters from free fatty acids under mild conditions was investigated. Free fatty acids are dissolved in a mixture of chloroform-methanolic HCl-cupric acetate and kept at room temperature for 30 min for complete esterification. The method is suitable for esterification of long-chain acids, such as 18:0, and for very long chain acids, such as 24:0. Fat...
