Abstract:An investigation was carried out to study the feasibility of using synthesized acid-bearing carbonaceous catalyst (SO3H–C and PO4H2–C) derived from cassava peel for biodiesel production from waste cooking oil (WCO). The catalyst activity was tested using an autoclave type reactor using three different oil to alcohol ratios (1 : 3, 1 : 5 and 1 : 7) at four different temperatures (50–80 °C) for 4 h. Two types of alcohol (i.e. methanol (CH3OH) and ethanol C2H5OH) were used to understand the efficiency of using al… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
