Biodiesel fuels potential yields

Fatty acid methyl esters (FAMEs) show large potential applications as diesel substitutes, also known as biodiesel fuel. Biodiesel fuel as renewable energy is an alternative that can reduce energy dependence on petroleum as well as air pollution. Several processes for the production of biodiesel fuel have been developed. Transesterification processes under alkali catalysis with short-chain alcohols give high yields of methyl esters in short reaction times. We investigated transesterification of rapeseed oil to produce the FAMEs. Experimental reaction conditions were molar ratio of oil to alcohol, concentration of catalyst, type of catalyst, reaction time, and temperature. The conversion ratio of rapeseed oil was enhanced by the alcohohoil mixing ratio and the reaction temperature. 

There has been growing interest in the application of methanol as an alternative fuel that can be directly used in Otto engines or fuel cells [1]. Its potential as an alternative fuel is due to its favorable combustion properties, which include low emission of particulates and nitrogen oxides [2], In addition, methanol is commonly used as an alcohol for producing biodiesel because of its low price, although other alcohols such as ethanol or isopropanol may yield a biodiesel fuel with better properties.
