I-Zeolite Catalyst NH4-ZSM-5

I-Henan Sinmat Chemical Co., Ltd. yenye yezona zinto zithembekileyo zabakhiqizi kunye nabanikezeli be-zeolite catalyst nh4-zsm-5 e-China. Ngamava amaninzi, siyakwamkela ngokufudumeleyo ukuba uthenge i-zeolite catalyst ekumgangatho ophezulu nh4-zsm-5 ithengiswa apha kumzi-mveliso wethu. Qhagamshelana nathi ngesampuli yasimahla.

I-Zeolite NH4-ZSM{10}}5 i-catalyst yi-ammonium{12}}ifom ye-molecular sieve ene-MFI framework, ekwaziwa ngokuba yi-ammonium ZSM{14}}5 zeolite, okanye i-ammonium ZSM{16}}5 isihluzo semolekyuli. I-NH4-I-ZSM-5 yi-ion exchange intermediate kunye ne-catalyst precursor ye-ZSM-5 ye-molecular sieves. Ayiqhelekanga ukusetyenziswa njenge-catalyst ye-acidic kwimveliso yokugqibela, kodwa kunokuba ibe yinto ebalulekileyo ekrwada yokulungiswa kwemizi-mveliso ye-ZSM-5 eguqulwe ngentsimbi efana ne-H-ZSM-5, CU-ZSM-5, FE-ZSM-5, kunye ne-CO-ZSM-5.

NH4-ZSM{7}}5 i-zeolite ye-molecular sieve ine-microporous structure ene-dimensional three-dimensional, equka iiseti ezimbini ze-intersecting channels. Ubungakanani bayo obuqhelekileyo bepore bumalunga ne-0.51-0.56 nm. Umlinganiselo we-silica-alumina we-NH4-ZSM-5 i-molecular sieve iyahlengahlengiswa, echaphazela i-acidity yayo kunye nenani leendawo ze-asidi.

Njenge-ion ebalulekileyo-i-precursor yotshintshiselwano, i-NH4-ZSM{5}}5 ibalulekile kulungiselelo lwe-H-ZSM-5 kunye ne-metal-exchangeable ZSM-5 zeolite catalysts. Ke ngoko, inezicelo eziphambili kwi-petroleum catalytic cracking kunye ne-aromatization. Njenge-acidic ZSM-5 catalyst precursor, i-NH4-ZSM-5 iphinde ibe yi-catalyst ye-zeolite ebalulekileyo ekuguqulweni kwe-methanol, njenge-MTO kunye ne-MTG.
