Iningi le-hydrogenation catalyst ye-alumina catalyst carrier yokuqala enephuzu eliphezulu lokuvutha, iphuzu eliphezulu lokuncibilika, okubonisa ukuthi iwuhlobo lwe-oxide ephikisayo, okwenza ukuthi izinto ezincane ezisakazeke kakhulu ze-catalyst zihlukane, ukuze kugwenywe ukuhlanganiswa kwe-catalyst carrier noma i-sintering okwesibili, i-alumina esigabeni ikhona ebangeni lokushisa elibanzi, futhi yenza isakhiwo sayo sangaphakathi ngaphansi kokushisa okuphezulu lapho ukuhlelwa kabusha kwekristalu kuzinzile emazingeni okushisa aphezulu, ukumelana nokuguguleka, ukusebenza okuhle kokudlulisa ukushisa ngaphezu kwalokho, ukuba khona kwe-acidic kanye ne-alkaline centre njenge-acid reaction endaweni ye-alkaline, futhi engasabela njenge-alkaline endaweni ye-acidic. Ngakho-ke, i-catalyst catalyst catalyst catalyst catalyst catalyst isekela futhi isakaze izinsimbi eziyigugu. Umphumela wokunciphisa ukusatshalaliswa kobuso bensimbi endaweni encane ezinzile usayizi wezinhlamvu ezincane uba ozinzile, akulula ukuqoqa futhi i-sintering ibaluleke kakhulu njengoba i-aluminium oxide ye-alumina, i-aluminium etafuleni kanye ne-mobile, yakha ama-oxide futhi ishiye umgodi, onengxenye ephezulu ye-void kanye nesitoreji esiningi, ingalungiswa izingxenye ze-catalytic isikhala sayo sangaphakathi, futhi ilungele ukusabalala esikhungweni esisebenzayo sama-reactants nemikhiqizo ishiya isikhungo esisebenzayo konke lokhu khombisa ukuthi i-alumina isebenza kahle kakhulu njengesithwali se-catalyst.
