HYDROCRACKING technique was applied here for producing ……petroleum- like fractions from waste frying oil. The experiments were performed in a fixed bed flow reactor system, under high pressure using zeolite catalyst. The operating conditions were optimized and found to be 400^oC, 2.5 MPa hydrogen pressure and 5 h^-1 LHSV.
The obtained biofuel was fractionated to gasoline, kerosene and gas oil- like fractions.  All the required analyses were accomplished and the data were evaluated. The results indicate that the properties of the attained products are completely compatible with those of the corresponding distillates ensued from petroleum source.
