Could some knowledgeable person explain the structure, properties, and catalytic mechanism of the light hydrocarbon aromatization catalyst GZ-10? The aromatization feedstock for my company is etherized C4 liquefied gas, and the catalyst is produced by Yangzi Fine Chemicals Company. I’m new to aromatization processes and would appreciate some guidance! . Note # ) # # , . hcbbs
Currently, the catalysts used for the aromatization of light hydrocarbons (LPG) are mainly based on ZSM-5 molecular sieves. The reaction mechanism involves the cracking, polymerization, cyclization, and dehydrogenation of hydrocarbon molecules (primarily olefins) under the action of the acidic sites on the catalyst, resulting in the formation of aromatic hydrocarbons and C5+ hydrocarbons. If only aromatic hydrocarbons are to be produced, a relatively high amount of dry gas is generated as a by-product. Gasoline is produced with very little dry gas; the main process involves the aromatization of olefins, and the products also contain large amounts of C3 and C4 alkanes.
Well, thank you. The mechanism you mentioned is included in my training materials, and the engineers also explained it to us using ZSM-5; but when the plant was finally put into operation, it was GZ-10 that was used in the reactor!
