Abstract

This study investigates the conversion of cabbage waste (CW) and low-density polyethylene (LDPE) into monocyclic aromatic hydrocarbons (MAHs) via a dual-stage pyrolysis-reforming process using a ZnO/CZSM-5 catalyst. Thermogravimetric analysis (TGA) is utilized to evaluate the thermal degradation patterns and assess the synergy between biomass and plastics during pyrolysis. Incorporating ZnO into the ZSM-5 catalyst significantly reduces polycyclic aromatic hydrocarbon (PAHs) production by decreasing ZSM-5 acidity. Under optimized operating conditions, which included a ZnO loading of 10 wt%, pyrolysis and reforming temperatures of 700 °C and 800 °C, respectively, and a feedstock-to-catalyst ratio of 2:1, MAHs of 68.5 % and a minimum of PAHs at 5.1 % were achieved. Characterization confirmed the structural integrity and catalytic efficacy of the ZnO/CZSM-5 catalyst. This study emphasizes the opportunities for converting biomass and plastic waste into valuable resources, thereby supporting sustainable energy initiatives and improving waste management strategies.

ZnO/ZSM-5催化剂催化白菜生物质与低密度聚乙烯共热解制备单环芳烃

研究了在ZnO/CZSM-5催化剂催化下，白菜废（CW）和低密度聚乙烯（LDPE）通过双阶段热解-重整工艺转化为单环芳烃（MAHs）。热重分析（TGA）用于评估热降解模式和评估生物质和塑料在热解过程中的协同作用。在ZSM-5催化剂中加入ZnO，通过降低ZSM-5的酸度，显著降低了多环芳烃（PAHs）的生成。在ZnO负载为10 wt%，热解和重整温度分别为700℃和800℃，料催化剂比为2:1的优化条件下，MAHs为68.5 %，PAHs最低为5. %。表征证实了ZnO/CZSM-5催化剂的结构完整性和催化效能。这项研究强调了将生物质和塑料废物转化为宝贵资源的机会，从而支持可持续能源倡议和改进废物管理战略。

期刊介绍： The Journal of Analytical and Applied Pyrolysis (JAAP) is devoted to the publication of papers dealing with innovative applications of pyrolysis processes, the characterization of products related to pyrolysis reactions, and investigations of reaction mechanism. To be considered by JAAP, a manuscript should present significant progress in these topics. The novelty must be satisfactorily argued in the cover letter. A manuscript with a cover letter to the editor not addressing the novelty is likely to be rejected without review.
