A Review of Biodiesel Production Process from Waste Cooking Oil: A comprehensive analysis of biodiesel production from waste cooking oil

Abstract

The need for safety and environmentally-friendly alternative energy sources has growth innow days due to the awareness of the negative impacts of fossil fuels on the atmosphere and the regularincrease in crude oil prices. Its specific characteristics such as a substantial decrease in emissions ofgreen house gas, non-sulfur emissions and non-particulate contaminants, low toxicity andbiodegradability. So biodiesels proved the best substitute for diesel. This article explores the chemicaland physical substances of Esterification, waste cooking oil, Transesterification and biodieselproduction by different methods and catalysts as yet mentioned. This article discusses pretreatment andwaste cooking oil. The factors which affect the process parameters mentioned are investigated and theemphasis is on the quantitative and qualitative scope of the alcohol oil relationship, the responsetemperatureand the catalyst. The optimal conditions are investigated and Biodiesel and petroleumdiesel which are exhausted emissions also comparison is made.
