Abstract
Utilization of zeolite activated by acid solution for biodiesel purification has been done. This research is conducted to find the mechanism of biodiesel purification from catalyst with activated zeolite, the effectiveness of the activated zeolite of various particle size, soaking time and purification temperature, the economic feasibility of biodiesel production by using this method and the more economical method by comparing the cost and performance of biodiesel purification using activated zeolite and using water and acid solution.This research has used cooking oil, methanol and sodium hydroxide to make biodiesel, sulfuric acid as activator and zeolite from Gunung Kidul which is filled into wash column with support from vacuum pump to purify biodiesel. The variable of the research is particle size of zeolite among others: 12 mesh
