Abstract:
The search for alternative fuels has gained importance due to the increase in the price of petroleum and environmental concerns about air pollution caused by the combustion of fossil fuels. Biodiesel is an immediate alternative solution for reducing petroleum consumption in an environment friendly manner. Biodiesel shows a decrease in the emission of CO2, SOx, NOx, and unburned hydrocarbons during the combustion process when compared with fossils fuels. Transesterification is the most common method used for biodiesel production, in which, according to stoichiometry, 1 mol of triglyceride reacts with 3 mol of alcohol (primarily methanol) in the presence of a catalyst (acid, base, or enzymatic), producing a mixture of fatty acid alkyl esters (biodiesel) and glycerol. Heterogeneous catalyst requires the high temperature and pressure for the reaction while homogenous catalyst leads to the formation of biodiesel under ambient reaction condition but contaminated with catalyst.
To overcome the difficulties with existing homogenous as well as heterogeneous catalysts, the present work demonstrates the preparation of Na+ metal ion impregnated calcium oxide as a solid nano catalyst for biodiesel production from waste cooking oil with high FFA and moisture contents.
