聚烯烃废塑料直接催化裂解研究进展
Progress in direct catalytic cracking of polyolefin waste plastics
摘要
Abstract
The extensive use of non-degradable plastics has led to severe environmental pollution.Transforming plastics into high-value-added chemicals not only enables the efficient recycling of waste plastics but also serves as an effective approach to address white pollution.Regarding the recycling of polyolefin waste plastics,this paper reviews the current research status of the catalytic cracking of waste plastics,encompassing aspects such as raw material pretreatment,the reaction mechanism of catalytic cracking,catalysts,and reactors.It also explores the influence of various factors on the transformation of waste plastics.Furthermore,prospects for the future development direction of the catalytic cracking of waste plastics,with an expectation of further advancing the industrial development of resource utilization of waste plastics are put forward.关键词
