Abstract

The review is focused on requirements for technical bifunctional catalysts containing, in addition to a metal phase and an acid support (zeolite), various components required for providing an effective heat and mass transfer and chemical or mechanical functions. Some catalytic reactions in which these components (e.g., a binder for extrusion) affect catalytic properties are discussed. A strategy of introducing metals into a shaped catalyst by deposition either on a zeolite or a binder, which affects the distance between the sites of various types and the catalytic properties of the resulting extrudates, is described.

中能级双功能催化

摘要

审查的重点是对工业双功能催化剂的要求，该催化剂除金属相和酸载体（沸石）外，还包含提供有效的传热和传质以及化学或机械功能所需的各种组分。讨论了其中这些组分（例如，用于挤出的粘合剂）影响催化性能的一些催化反应。描述了一种通过沉积在沸石或粘合剂上而将金属引入成形催化剂中的策略，这会影响各种类型的位点之间的距离和所得挤出物的催化性能。
