Chithandizo cha chothandizira cha Alpha alumina

Kufotokozera Kwachidule:

α-Al2O3 ndi chinthu chokhala ndi mapokoso, chomwe nthawi zambiri chimagwiritsidwa ntchito pothandizira ma catalyst, adsorbents, zinthu zolekanitsa magawo a gasi, ndi zina zotero. α-Al2O3 ndi gawo lokhazikika kwambiri la alumina yonse ndipo nthawi zambiri limagwiritsidwa ntchito pothandizira zigawo zogwira ntchito za catalyst ndi chiŵerengero cha ntchito yayikulu. Kukula kwa mapokoso a chonyamulira cha α-Al2O3 ndi kwakukulu kwambiri kuposa njira yopanda mamolekyulu, ndipo kufalikira kwake ndi kofanana, kotero vuto la kufalikira kwamkati lomwe limayambitsidwa ndi kukula kwa mapokoso ang'onoang'ono mu dongosolo la catalytic reaction likhoza kuthetsedwa bwino, ndipo zotsatira zakuya za okosijeni zimatha kuchepetsedwa panthawiyi kuti cholinga cha oxidation chikhale chosankha. Mwachitsanzo, chothandizira chasiliva chomwe chimagwiritsidwa ntchito popangira ethylene oxidation ku ethylene oxide chimagwiritsa ntchito α-Al2O3 ngati chonyamulira. Nthawi zambiri chimagwiritsidwa ntchito pochita zinthu zoyambitsa ndi kutentha kwambiri komanso kulamulira kufalikira kwakunja.
