Abstract
There is increasing effort in biodiesel production (fatty acid methyl ester) because of the depleting fossil fuel resources as well as similarity in properties when compared to those of diesel fuels. Diesel engines operated on biodiesel have lower emissions of carbon monoxide, unburned hydrocarbons and air toxics than those operated on petroleum-based diesel fuel. Herein we reported the optimization of Black and Castor oils methyl esters production via KOH catalyzed transesterification under various superintended conditions. The optimum yield, temperature, catalyst concentration and reaction time found to be 97%, 60°C, 1.0% (wt of crude black/castor oil) and 45 minutes respectively. A number of the fuel properties (viscosity, specific gravity and flash point) were measured according to standard methods, and were found to conform to international standards.
