摘要
结合催化裂解多产低碳烯烃催化剂活性组分的研发需求,综述了从调变酸性质、改善孔道结构和增强水热稳定性3个方面改性ZSM-5分子筛,以及过渡金属改性ZSM-5分子筛方面的当前研究进展,并对今后改性方向与重点进行了展望。
Combining with the research and development demands of catalytic pyrolysis to maximize light olefins,advances in modified ZSM-5 zeolites were reviewed in 3 aspects:acid properties adjustments,pore structure modification and hydrothermal stability improvement.The current research progress of ZSM-5 zeolites modified with transition metal were also introduced.The direction and focus of further modification of ZSM-5 zeolites in the near future was prospected.
