本文介绍了分子筛催化剂的择形性能和这一领域的进展。阐明了Y型分子筛、丝光沸石、高硅沸石(ZSM型)的通道大小与择形性能的关系;并叙述了用这种分子筛或沸石做成的催化剂在石油化工方面的应用;还介绍了过渡金属交换型分子筛和金属负载型分子筛在择形催化性能方面的探索。
This article describes the shape-selective properties of molecular sieve catalysts and advances in this area. The relationship between channel size and shape selectivity of Y zeolite, mordenite and high silica zeolite (ZSM) was clarified. The application of this catalyst made of zeolite or zeolite in petrochemical industry was also introduced. The transition Exploration on Shape - Selective Catalytic Performance of Metal - Exchange Zeolites and Metallic Supported Zeolites.
