Because of the continuous increase in the amount of plastic waste, catalytic cracking is an interesting method that could be used to convert heavy oil from thermal cracking of plastic waste into fuel. The objective of this study was to investigate the hydrodynamic behavior and the performance of catalytic cracking of heavy oil in a circulating fluidized bed reactor using computational fluid dynamics. The two– fluid model incorporated with the kinetic theory of granular flow was applied to predict the hydrodynamic behavior with a reactive flow. Three reactor geometries were studied, which included a conventional riser, tapered–out riser, and tapered–in riser. The four–lump kinetic model was used to describe the catalytic cracking of heavy oil from waste plastic. A core–annulus flow pattern was found in the three reactor geometries. The solid fraction distribution of the tapered reactor was found to be more uniform than that of the conventional riser. The tapered–in riser showed the highest heavy oil conversion with the lowest gasoline selectivity. However, the heavy oil conversion and gasoline selectivity of the conventional and tapered–out reactors were not significantly different.

Liquid fuels from polypropylene plastic waste have been successfully performed by catalytic cracking method. The catalyst used is Al-MCM-41- Ceramics. The catalyst was characterized by XRD, SEM, Pyridine-FTIR, N2-Adsorption-Desorption, and the product of catalytic cracking were investigated by gas chromatography-mass spectroscopy (GC-MS). The catalyst was using three times at sample notify A,B and C. The results showed liquid fuels have the largest percentage of gasoline (C8-C12) are 92.76; 91.92 and 90.58 percent fraction produced. The performance of catalyst showed that reuseability number were decrease, but the charactersitic of liquid fuel produced were also be agreeable to commercial gasoline standard. Keywords: olypropylene waste plastics, liquid fuels, catalytic conversion, Al-MCM-41-Cer catalyst, reuseability number.

Indonesia with a very large population, is currently working hard to diversify its energy, in order to meet energy needs in the country, especially electricity and fuel energy, preferably environmentally friendly renewable energy, when this plastic waste becomes national problems because they cannot decompose under ordinary conditions unless they are converted into chemical fuel. This study aims to obtain liquid fuel energy, in this case used HDPE plastic waste raw material (in the form of packaged drinking water), this plastic waste is processed using the Catalitic Cracking method with silica Alumina as a catalyst, the process lasts for 4 hours with a temperature of 100 -400oC and 53% of the plastic oil obtained, brownish yellow, with density and viscosity and flash point approaching kerosine compounds to diesel fuel, in the process of catalytic cracking, temperature factors, process length and the catalyst used greatly affect the number of products and product quality from the liquid fuel produced.

Polystyrene is useful product that widely used today.  But when it becomes waste, Polystyrene can cause environmental problem such as air pollution, soil contamination, as well as economical resistence due to the increase of space and disposal costs.  On the other hand Polystyrene can be converted into fuel.  It is expected can be a solution of the problem.  The aim of this research is to convert polystyrene plastic waste into useful fuel with catalytic cracking process.  Zeolit and Al2O3 was used as catalyst in this research as musch as 8 % feed.  Temperature set at 250 oC.  At the optimum reaction condition (catalyst Al2O3 and the length of cracking time is 30 minutes) the liquid yield of catalytic cracking process was 29.40 %.  Physical properties like density, spgr, oAPI gravity and calorific value of fuel samples is determined and compared to gasoline standard. The result showed that density, spgr, oAPI gravity and calorific value was close to the density, spgr, oAPI gravity and calorific value of gasoline standard.
