Sažetak
In the search of an economical process for bio- diesel synthesis, waste cooking oil was analyzed as a poten-tial feedstock. The influence of different concentrations and granulations of the zeolite catalyst on the yield and quality of the final product was also investigated.The process of transesterification with methanol was found to be suitable due to the high conversion of waste oil esters under relatively mild reaction conditions. Moreover, modified natural clinoptilolite proved to be a suitable catalyst for the process of biodiesel production. At each catalyst concentration and granulation, the biodiesel yield was satisfactory and its quality parameters met the prescribed standards.
