Abstract

Crude oil is a source of energy which cannot be renewable and can be run out sometime. This fact motivates so much countries economizing on fuel and do many research to gets another fuel which can be substitued crude oil. This alternative is Biodiesel which can substitued diesel. Biodiesel is represent as fuel which can substitute diesel fuel, and its produce from vegetable oil. Commonly biodiesel made from vegetable oil esterification and transesterification process. In the other side ex-cooking oil is waste-product from food industry, restaurant and household which have great potention to become fuels because the high contents of carbon and hydrogen atoms. But if using esterification and transesterification process to ex-cooking oil material, it is not economize because makes another reaction between alkaly catalist and oil to produce soap. One of making biodiesel process is catalytic cracking to the ex-cooking oil. This research obtain to decide zeolite catalist size effect ( 0.125mm; 0.3375mm; 0.425mm; 0.85mm; 1.18mm ), and acid concentration to the product ( 2N; 3N; 4N ). This result shows at 4N acid concentration and 0.125 mm zeolite catalist size is the optimal result can reach characteristic of diesel specification.
