Ukusekelwa kwe-Alpha alumina catalyst

Incazelo emfushane:

I-α-Al2O3 iyimpahla enezimbobo, evame 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 ezinezinga eliphezulu lomsebenzi. . Ubukhulu bembotshana ye-α-Al2O3 catalyst carrier bukhulu kakhulu kunendlela yamahhala yama-molecular, futhi ukusatshalaliswa kuyafana, ngakho-ke inkinga yokusabalalisa yangaphakathi ebangelwa usayizi omncane wembotshana ohlelweni lwe-catalytic reaction ingaqedwa kangcono, kanye ne-oxidation ejulile. ukusabela okuseceleni kungancishiswa kunqubo ngenjongo ye-oxidation ekhethiwe. 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.
