Ko te α-Al2O3 he rauemi porous, he maha nga wa e whakamahia ana mo te tautoko i nga whakakōkī, adsorbents, rauemi wehenga hau, me etahi atu. . Ko te rahi o te pore o te α-Al2O3 catalyst carrier he nui noa atu i te huarahi molecular free, a he rite te tohatoha, na te raruraru o roto i puta mai i te iti o te pore i roto i te punaha tauhohenga catalytic ka taea te whakakore pai ake, me te whakapouri hohonu. Ka taea te whakaheke i nga tauhohenga taha i roto i te tukanga mo te kaupapa o te whakapouritanga whiriwhiri. Hei tauira, ko te whakakorikori hiriwa e whakamahia ana mo te ethylene oxidation ki te ethylene oxide e whakamahi ana i te α-Al2O3 hei kawe. He maha nga wa e whakamahia ana i roto i nga tauhohenga catalytic me te teitei o te pāmahana me te mana tohatoha o waho.
