Biodiesel is a mixture of mono-alkyl esters of long chain fatty acids derived from a renewable lipid feedstock. It can be used as an alternative fuel as the fossil fuels are getting depleted tremendously. In current scenario, in spite of fulfilling energy demand, use of biodiesel leads to the substantial reduction in the pollution caused by PM, HC and CO. Current study mainly focused on production of biodiesel from waste cooking oil using alkaline catalysts NAOH and KOH and co-solvent acetone in the presence of methanol. Waste cooking oil is used because of its high oil content and abundant availability. We have employed co-solvent method to produce biodiesel.
Petrol and Diesel are commercially used fuels in engines. Few distract actions are encountered while auto-ignition due to presence of water and rust in the engine, as the fuel are properties are determined and understood by analysing flash point of petrol and diesel samples. Since increase in flash points are due to presence of water, which shows free water drops is found to exhibit negative effects present in tested diesel and petrol. Present study helps to determine/analyse the quality of fuel from the bottom of the tank which is predominantly has water drops and rust particles.
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.
