Ukusekelwa kwe-Alpha alumina catalyst

Incazelo emfushane:

I-α-Al2O3 iyisisetshenziswa esinezimbotshana, esivame ukusetshenziselwa ukusekela ama-catalysts, ama-adsorbents, izinto zokuhlukanisa isigaba segesi, njll. I-α-Al2O3 iyisigaba esizinzile kunazo zonke ze-alumina futhi ngokuvamile isetshenziselwa ukusekela izingxenye ezisebenzayo ze-catalyst ngesilinganiso esiphezulu somsebenzi. Ubukhulu bembotshana yesithwali se-α-Al2O3 ye-catalyst bukhulu kakhulu kunendlela yamahhala yamangqamuzana, futhi ukusatshalaliswa kuyafana, ngakho-ke inkinga yokusabalalisa yangaphakathi ebangelwa usayizi omncane wembotshana ohlelweni lwe-catalytic reaction ingaqedwa kangcono, futhi ukusabela okujulile ohlangothini lwe-oxidation kungancishiswa enqubweni ngenjongo yokukhetha i-oxidation. Isibonelo, i-catalyst eyisiliva esetshenziselwa i-ethylene oxidation ku-ethylene oxide isebenzisa i-α-Al2O3 njengesithwali. Ivame ukusetshenziswa ekuphenduleni kwe-catalytic ngezinga lokushisa eliphezulu kanye nokulawulwa kokusabalalisa kwangaphandle.
