以固体为催化剂的异相催化反应可以分为离子型和电子型两大类;石油以及化学工业中許多是以酸性固体如H_3PO_4——硅藻土、AlCl_3-Al_2O_3,SiO_2-Al_2O_3等为催化剂的反应,如裂解、异构、烃化、聚合等都是离子型的。最近所得烃类在这些催化剂表面上的化学吸
Heterogeneous catalytic reactions with solid as catalyst can be divided into two major categories: ionic and electronic; many of the petroleum and chemical industries are based on acidic solids such as H_3PO_4-diatomaceous earth, AlCl_3-Al_2O_3, SiO_2-Al_2O_3 and the like Reactions, such as lysis, isomerization, alkylation, polymerization and the like, are ionic. Recent chemisorption of hydrocarbons on the surface of these catalysts
