Researchers from Malaysia performed an experiment to analyse the efficiency
of biodiesel conversion from crude castor oil to castor oil biodiesel. Acid-base catalysed transesterification reaction was carried out under different reaction conditions to obtain high yield of castor biodiesel.
Diesel engine performance and emission tests with different castor biodiesel blends showed that B20 blend of castor biodiesel had same engine power output as other mineral diesel with lower average percentage of change in CO and HC emissions. Thus, B20 blend of castor biodiesel could be a suitable alternative to diesel.
