摘要：

The effects of oxidizing and reducing treatments over Ga/H-ZSM-5 aromatization catalysts are studied, The respective roles of the dehydrogenation function and of the acid function are discussed and it appears that the acid function is depressed through the reducing treatment. To explain the role of gallium in propane activation, the concept of the dual-site mechanism is preferred to the concept of the ''porthole'' mechanism. (C) 1995 Academic Press, Inc.
