| Summary: | In this study, the efficiency of biodiesel conversion from crude castor oil to castor biodiesel (CB)
through transesterification method was investigated. The acid-base catalyzed transesterification under
different reaction condition such as the molar ratio of alcohol and mass ratio of catalyst to oil was
studied for optimum proportion to achieve highest yield of Castor biodiesel. The optimum condition
for acid-base catalyzed transesterification was determined to be 0.22 oil/methanol (v/v) and 0.005
KOH/oil (v/v). The potential of CaCO3 to be used as solid base catalyst for transesterification of castor
oil was also investigated. Then the fuel properties of the produced castor biodiesel such as the calorific
value, flash point and density were analyzed. Component analysis was carried out by using FT-IR. The
diesel engine performance and emission test using different castor biodiesel blends were then
conducted. B20 blend of castor biodiesel was proved to have the same engine power output as mineral
diesel with lower average percentage of change in CO, PM and HC emissions compared to mineral
diesel. Thus a B20 blend of castor biodiesel was a suitable alternative fuel for diesel. |
