Alpha alumina catalyst tšehetso

Tlhaloso e Khutšoanyane:

α-Al2O3 ke lisebelisoa tse nang le porous, tse atisang ho sebelisoa bakeng sa ho tšehetsa li-catalysts, adsorbents, lisebelisoa tsa ho arohana ha karolo ea khase, joalo-joalo α-Al2O3 ke karolo e tsitsitseng ka ho fetisisa ea alumina eohle 'me hangata e sebelisetsoa ho tšehetsa likarolo tse sebetsang tsa catalyst tse nang le tekanyo e phahameng ea mosebetsi. . Boholo ba pore ea α-Al2O3 catalyst carrier e kholo haholo ho feta tsela e sa lefelloeng ea limolek'hule, 'me kabo e tšoana, kahoo bothata ba ka hare ba phallo e bakoang ke boholo bo nyane ba pore tsamaisong ea catalytic reaction e ka felisoa hantle,' me ho teba ha oxidation. karabelo ea lehlakore e ka fokotsoa ts'ebetsong ka sepheo sa ho khetha oxidation. Mohlala, sesebelisoa sa silevera se sebelisoang bakeng sa oxidation ea ethylene ho ethylene oxide se sebelisa α-Al2O3 joalo ka sejari. Hangata e sebelisoa ka liketso tsa catalytic ka mocheso o phahameng le taolo ea ho hasana ka ntle.
