Usekelo lwe-Alpha alumina catalyst

Incazelo emfushane:

I-α-Al2O3 iyinto enezimbobo, evame ukusetshenziselwa ukusekela ama-catalyst, ama-adsorbents, izinto zokuhlukanisa isigaba segesi, njll. I-α-Al2O3 iyisigaba esizinzile kakhulu sazo zonke i-alumina futhi ivame ukusetshenziselwa ukusekela izingxenye ezisebenzayo ze-catalyst ezinesilinganiso somsebenzi esiphezulu. Usayizi wembobo yesithwali se-catalyst se-α-Al2O3 sikhulu kakhulu kunendlela yamahhala yama-molecule, futhi ukusatshalaliswa kuyafana, ngakho-ke inkinga yokusatshalaliswa kwangaphakathi okubangelwa usayizi wembobo encane ohlelweni lokusabela kwe-catalytic ingasuswa kangcono, futhi ukusabela okujulile kwe-oxidation kungancishiswa enkambisweni ngenhloso yokusatshalaliswa okukhethayo. Isibonelo, isithasiselo sesiliva esisetshenziselwa ukusatshalaliswa kwe-ethylene ku-ethylene oxide sisebenzisa i-α-Al2O3 njengesithwali. Ivame ukusetshenziswa ekusatshalalisweni kwe-catalytic ngokushisa okuphezulu kanye nokulawula ukusatshalaliswa kwangaphandle.
