Liquid fuel from polystyrene plastic waste with co-reactant of cooking oil waste biodiesel has been obtained. The catalysts used in catalytic cracking are Al-MCM-41/ceramic and Pd/Al-MCM-41/ceramic catalysts. Morphology and elemental composition were observed with SEM EDX, the crystal structure observed with XRD, surface area and pore volume were analyzed by Nitrogen adsorption-desorption each calculated by BET and BJH method, acidity determined by FTIR-Pyridine, and temperature resistance analyzed by DTA. The results of catalytic cracking were investigated using Gas Chromatography-Mass Spectroscopy (GC-MS). Characterization of the catalyst showed that acidity was reduced because the Si/Al ratio was reduced after the impregnation and the surface area of Al-MCM-41/ceramics also decreased. SEM EDX shows that the composition of the carbon element on the surface of the Pd/Al- MCM-41/ceramic catalyst is smaller compared to the Al-MCM-41/ceramic catalyst. The results of the GC-MS characterization of liquid fuels from catalytic cracking using Pd/Al- MCM-41/ceramics catalyst, have a percentage of gasoline fraction (C7-C12) of 74.9% at 120 minutes cracking. The mixture of fuel from the addition of 150 mL liquid fuel resulting from catalytic cracking with Pd/Al-MCM-41/ceramic catalyst has the highest calorific value of 19160.61 (kcal/kg) and the performance of the gasoline Genset engine has the highest thermal efficiency of 28.27%.
