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.

Adsorption Desorption

Five kinds of modified Y zeolite-based fluid catalytic cracking (FCC) catalysts were prepared. The N2 adsorption desorption and NH3 temperature-programmed-desorption (NH3-TPD) were used to investigate the pore structure and acidic properties of the catalysts. The effects of pore structure and acidic properties of catalysts on the catalytic cracking performance of Venezuelan heavy oil were carried out using an advanced cracking evaluation unit. The results of N2 adsorption desorption and NH3-TPD show that CAT-A and CAT-B catalysts with rundle pore distribution have a similar pore sizes and acidSubscript textSubscript textic properties. The catalytic cracking results show that the acidic properties and the pore distribution of the catalysts have obvious effects on the conversion and product distribution. The light oil yield and total liquid oil yield can reach 58.75wt% and 73.83 wt%, respectively, under reaction temperature of 520°C.
