This presentation discusses catalytic cracking and hydrocracking of polyolefin waste using laboratory-synthesized, optimized zeolite beta and Ru/zeolite beta catalysts in an open-batch reaction system. Emphasis is placed on identifying external surface acid sites of zeolite beta as critical to enhancing liquid product selectivity. Reactor configuration optimization further increased liquid selectivity, achieving up to 75 % yield within a moderate temperature range of 300–330 °C. These findings provide significant insights into catalyst design and reactor engineering, highlighting practical pathways for efficient chemical recycling of polyolefin waste into valuable liquid hydrocarbons.
