Abstract: 5wt% Al-impregnated zeolite beta catalyst is synthesized and characterized by well-known catalyst characterization techniques. A model municipal waste plastic mixture consisting of LDPE, HDPE, PP, and PS is hydrocracked over the catalyst. The experiments are performed in a high pressure autoclave reactor at three reaction temperatures, 360°C, 375°C, and 400°C and at cold hydrogen pressure of 20 bar. The feed to catalyst ratio is maintained at 20:1 (by weight). At 400°C, 95.7% conversion with 60.8% liquid yield is the result.

Key words: Waste plastics, chemical recycling, hydrocracking, hierarchical catalyst, zeolite beta.
