ZSM-5 moʻo Zeolites koho
Hiki ke hoʻohana ʻia ʻo ZSM-5 zeolite no ka ʻoihana petrochemical, ʻoihana kemika maikaʻi a me nā māla ʻē aʻe ma muli o kāna ʻano ʻekolu-dimensional cross straight pore canal, kūikawā shape-choliability crackability, isomerization a me ka hiki ke aromatization.I kēia manawa, hiki iā lākou ke hoʻopili i ka FCC catalyst a i ʻole nā mea hoʻohui e hiki ke hoʻomaikaʻi i ka helu octane gasoline, hydro/aonhydro dewaxing catalysts a me ke kaʻina hana xylene isomerization, toluene disproportionation a me alkylation.Hiki ke hoʻonui ʻia ka helu octane gasoline a hiki ke hoʻonui ʻia ka ʻike olefin inā hoʻohui ʻia nā zeolites i ka catalyst FCC i ka hopena FBR-FCC.I loko o kā mākou hui, ʻo ka ZSM-5 serial shape-selective zeolites he silica-alumina ratio like ʻole, mai 25 a hiki i 500. Hiki ke hoʻololi ʻia ka puʻupuʻu ʻāpana e like me nā koi o nā mea kūʻai aku.Hiki ke hoʻololi ʻia ka hiki ke isomerization a me ke kūpaʻa hana ke hoʻololi ʻia ka acidity ma ka hoʻololi ʻana i ka ratio silica-alumina e like me kāu mau koi.

| Ka Hana Hana Hana: Ma lalo o ka wela kiʻekiʻe a me ke kūlana kiʻekiʻe, e hana ʻia ka ZSM-5 zeolites ma hope o ka hydrothermal compound crystallization, kānana, holoi, hoʻololi a hoʻomaloʻo me ka hoʻohana ʻana i ka paʻakai alumini a me ka silicate ma ke ʻano he mea nui. | ||
