Abstract

High variation in global price of petroleum crude oil has an inauspicious impact on national economy of crude oil dependant countries like India. As per the survey, petroleum crude oil consumption in India was 3.182 million barrels/day in 2010 and oils consumption is growing fast, in 2002 consumption rate increases by 3.28% while in 2010, it increases by 6.77%. Therefore, looking for the eco friendly alternative path to produce replacement for the petroleum based fuel like diesel is the recent task for green technologists. Transesterification reaction of frying oil generally known as waste cooking oil with alcohol (methanol or ethanol or both) in presence of various different catalysts to synthesis transesterified product i.e. biodiesel is the future need as the alternative energy source because of depletion of fossil fuels. The comparisons of the biodiesel production from waste cooking oil using various methods were also reviewed in this paper. This paper reviews the work that has been already studied in biodiesel production technologies from waste cooking oils.
