<p>Liquid fuel from polystyrene waste and waste cooking oil biodiesel was successfully obtained through catalytic cracking using Al-MCM-41/Ceramic. The structure, morphology, acidity, and porosity of the catalyst were studied by SEM-EDX, pyridine FTIR, and N<sub>2</sub> gas adsorption-desorption. The products of catalytic cracking were analyzed using gas chromatogram-mass spectroscopy (GC-MS). The highest yield was obtained at feedstock variations of 57% (P): 43% (M) with the number of hydrocarbon fractions (&lt; C<sub>7</sub>) is 0.48%, hydrocarbon fraction (C<sub>8 </sub>- C<sub>12</sub>) is 20.99%, and hydrocarbon fraction (&gt; C<sub>12</sub>) is 78.53% in the cracking time 1 hours. Physical characteristics were reported in the form of density, flash point, and caloric value respective. The performance of liquid fuels with commercial fuels, Premium (RON 88), and additives of methyl tertiary butyl ether (MTBE) comparisons of 225 (mL): 750 (mL): 18.25 (mL) respectively produce thermal efficiency on engine use gasoline generator sets was 28.22% at the load of 2118 Watts. Based on this research, all variations of feedstock produce liquid fuels that are in accordance with SNI 06-3506-1994 concerning the quality of gasoline fuel types.</p><p> </p>Keywords: Catalytic cracking, polystyrene waste, waste cooking oil, liquid fuel

Abstract Background Biomass fuels (bio-jet fuel) have recently attracted considerable attention as alternatives to conventional jet fuel. They have become the focus of aircraft manufacturers, engines, oil companies, governments and researchers alike. This study is concerned with the production of biojet fuel using waste cooking oil (WCO). Batch reactor is used for running the experimental study. The catalytic cracking products are investigated by GC mass spectra. Final products from different reaction conditions are subjected to fractional distillation. The (Bio kerosene) fraction was compared with the conventional jet A-1 and showed that it met the basic jet fuel specifications. Optimum reaction conditions are obtained at (450 °C), pressure of (120 bars), catalyst dose (2.5% w/v), reaction time (60 min) and hydrogen pressure 4 atmosphere. The aim of this study is to produce bio aviation fuel according to specifications and with a low freezing point from waste cooking oil in one step using a laboratory prepared catalyst and with a low percentage of hydrogen to complete the process of cracking and deoxygenation in one reactor, which is naturally reflected positively on the price of the final product of bio aviation fuel. Results The results indicated that the product obtained from WCO shows promising potential bio aviation fuels, having a low freezing point (− 55 °C) and that all bio kerosene’s specifications obtained at these conditions follow the international standard specifications of aviation turbine fuel. Conclusion Biojet fuel obtained from WCO has fairly acceptable physico-chemical properties compared to those of petroleum-based fuel. Adjustment of the hydro catalytic cracking reaction conditions was used to control quantities and characteristics of produced bio aviation fuel. Taking into consideration the economic evaluation WCO is preferable as raw material for bio aviation fuel production due to its low cost and its contribution in environmental pollution abatement. Blend of 5% bio aviation with jet A-1 (by volume) can be used in the engine without any modifications and a successful test of blended aviation fuel with 10% bio aviation has been achieved on Jet-Cat 80/120 engine.

The average consumption rate of cooking oil in Indonesia on 2019 was 61 million litre. Because of that makes the waste cooking oil produces very high to. To prevent the consument littering the waste cooking oil, we can recycle it to be biofuel with many fraction such as biodiesel, biogasoline, and biokerosene. There are many ways to process the waste cooking oil to be, biofuel one of them is catalytic cracking. This study is induct by observe the biofuel that form from the catalytic cracking process with cooking oil as the base material using a hybrid catalyst ZSM-5/Alumina. The purpose of this study is to observe the influence of ZSM-5 and Alumina ratio as heterogenic catalyst and also the used of the catalyst frequently. The highest conversion of liquid product was produce with value 41,67%  at alumina variation of 17,5%. The used of catalyst frequently will affect the decrease amount of liquid product that produce. The analysis of chemical properties using GC-MS obtained the amount of kerosene 29,917 %; gasoline 3,996 %; and diesel 10,1 %. The other product was carboxylics acids,alcohol, and unidentified compound.   Keyword : Cooking oil, biofuel, ZSM-5, Alumina, catalytic cracking
