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.

Dual Fluidized Bed

Funabashi City’s Municipal Solid Waste Pyrolysis Plant is the first full-scale plant having a dual fluidized bed gasification system. The plant has the capacity of processing 4.5 × 105 kg/day of mixed municipal solid waste with a very limited emission of air, water and land pollutants. The energy is recovered as high calorific value fuel gas. Since April 1983, the plant has been in continuous operation. The purpose of this paper is to report on the system and the experience obtained during the 5 mo in which it was in operation. Data on the material balance of the pyrolysis, the analysis regarding the gas produced, the flue gas composition and the equipment used are included.
