The purpose of this research study the effect of two variables on yield (%) resulting product, knowing the main constituent component of biofuels and the best conditions of the catalytic cracking process used cooking oil. Of research, yield (%) highest product of 69.71% is obtained at a temperature of 400oC and the concentration of Fe / Mo 1% by weight. GC-MS analysis of the results obtained the highest conversion of biofuel product that is equal to 67.99% at 400oC temperature and concentration of metal Fe / Mo 1% by weight.otherbiofuelwaste cooking oilFe/Mocatalytic crackingstudent Paper Post Degree
