I-Henan Sinmat Chemical Co., Ltd. yenye yezona zinto zithembekileyo zabakhiqizi kunye nabanikezeli be-amorphous silica alumina catalyst e-China. Ngamava amaninzi, siyakwamkela ngokufudumeleyo ukuba uthenge umgangatho ophezulu we-amorphous silica alumina catalyst ethengiswa apha kumzi-mveliso wethu. Qhagamshelana nathi ngesampuli yasimahla.
Intshayelelo
I-amorphous silica{0}}i-alumina (ASA) ichazwa njengengeyiyo-i-crystalline aluminosilicate imathiriyeli equlunqwe ikakhulu ngesilika (SiO2) kunye ne-alumina (Al2O3), isebenza njenge-heterogeneous catalyst inkxaso ephawulwa yi-turable medium-amandla acidity kunye nokungabikho{1}}kuluhlu olude lokulandelelana kweathom. Esi sixhobo sivela kumxube osondeleyo we-silica kunye nezigaba ze-alumina, okubangelwa i-asidi eqinile kunye neendawo zombini ze-Brønsted kunye ne-Lewis acid eyenza ukusetyenziswa kwayo kwiinkqubo ze-catalytic. Ngokungafaniyo noogxa becrystalline abanje nge-zeolites, i-ASA catalyst ibonisa ubume obungacwangciswanga obubonelela ngofikelelo oluphezulu lwe-reactants ngaphandle kwemida yokusabalalisa kwi-micropores.
I-ASA catalyst ilungiswa ngesol-indlela yejeli, kunye nesilicon kunye ne-aluminiyam edityanisiweyo kwisikali seathom kwaye isasazwe ngokulinganayo. Njengoncedo oluphezulu - lwe-catalyst, i-ASA catalyst ibonisa amaziko e-asidi afanayo, umthamo omkhulu wepore, indawo enkulu yendawo ethile, ukuhanjiswa kwepore okugxininisiweyo, ukucoceka okuphezulu, kunye nomlinganiselo we-Si / Al ohlengahlengiswayo.
I-ASA amorphous silica{0}}i-alumina, ikwabizwa ngokuba yi-Amorphous Silica{1}}i-Alumina Xerogel, okanye ngokulula i-ASA Xerogel. Ngokuqhelekileyo ibonakala njengomgubo omhlophe. Olona setyenziso luphambili lwe-amorphous silica{4}}i-alumina powder ifana ne-FCC catalyst matrix, ibonelela ngezakhiwo ze-mesoporous, ngaphambili{5}}ukuqhekeka kwe-oyile enzima, ukuphucula ukusasazwa, kunye nokunyusa isivuno sepetroli. Ikwasebenza njenge-hydrocracking catalyst carrier, ukulayisha i-Ni, W, Mo, njl. Ukongeza, i-ASA Xerogel ingasetyenziswa njenge-isomerization catalyst, i-dehydration catalyst, kunye ne-adsorbent.
