Abstract: This purpose, zinc and nickel were chosen as the catalytic materials and Calophyllum inophyllum was chosen as the feedstock for biodiesel production. Experimental results proved maximum reduction of hydrocarbon emissions by 14.8%, carbon monoxide emissions by 21.89% and smoke opacity by 13.22% for nickel coated catalytic converter. However, carbon dioxide and nitrogen oxides emission levels increased by 22% and 5.5%, respectively for nickel coated catalytic converter. On the other hand, zinc coated catalytic converter exhibited an increase of all emission levels except nitrogen oxides. The reduction level of nitrogen oxides with zinc coated catalytic converter was observed as 34.2%. Through this work it is revealed that nickel acts as an oxidative catalytic agent and zinc as the reducing catalyst in the catalytic converter.
