Abstract
Two vegetable oils were used to obtain Jet biofuels by catalytic cracking using two acidic catalysts (alumina and clay). The reaction conditions were studied including: catalyst ratio (0.2-1%), reaction time and temperature. The obtained biojet fuels were specified and compared according to ASTM specifications. The results of the study showed that the produced biojets are comparable to the petroleum derivatives. Increasing the catalyst ratio, time and temperature of the process were increased the efficiency of the produced fuels and narrow the differences between their properties and the commercial fuel. The obtained fuels were blended by JET A-1 in different ratios and the results of the blends were studied according to ASTM specifications.
