Abstract

The recycling of waste plastics has become an increasingly important issue in recent years due to the enormous use of plastics in almost every aspect of modern life. Considering current conditions and expected future trends of the Saudi economy, the coprocessing of waste plastics with petroleum resid appears to be an attractive option for further studies. Our present ongoing study evaluated the effects of three different catalysts on the conversion and product distribution obtained from the coprocessing of heavy petroleum resid and waste plastics. The plastics used in this study were model polyethylenes (LDPE and HDPE), polypropylene, and polystyrene as well as post consumer waste plastics. The coprocessing of various plastics with petroleum resid was found to be affected by catalyst type. The presence of hydrocracking selectivities during reaction increased conversion and product distribution of hexane soluble materials. At reaction conditions of 60 min and 430 °C, catalysts with substantial hydrocracking activity yielded high levels of conversion to liquid fuel products. The coprocessing of waste plastics with resid appears to be a feasible process by which to convert resid and waste plastics simultaneously to liquid fuels and to upgrade both the resid and waste plastics materials.
