A critical review on production of biodiesel from various feedstock

Abstract

Biodiesel fuel produced by alcoholysis of edible, non-edible and waste cooking oil is viewed as a promising renewable fuel source. Diminishing petroleum reserves and increasing environmental regulations have made the search for renewable fuel. This paper focuses on review of a work carried out by researchers in the field of production of biodiesel from different types of oil. The raw oil used by researchers for production of biodiesel first briefly summarized followed by a description of biodiesel production method applied and yield percentage, FFA content, molar ratio and the reaction time of the biodiesel produced from the raw oil. The review is divided into three categories viz. production of biodiesel from edible oil, non-edible oil and waste cooking oil. This review paper contains the work of past researchers published between 2005 and 2015.
