Chifukwa chogwiritsira ntchito ufa wa alumina ngati chonyamulira chothandizira

Chothandizira kwambiri cha hydrogenation cha chonyamulira cha alumina chothandizira choyamba chokhala ndi malo oyatsira moto kwambiri, malo osungunuka kwambiri, zomwe zimasonyeza kuti ndi mtundu wa oxide wotsutsa, zomwe zimapangitsa kuti tinthu tating'onoting'ono tomwe timatulutsa tinthu tating'onoting'ono tomwe timafalikira kwambiri tisiyane, kuti tipewe kusonkhana kwa chonyamulira cha chothandizira chachiwiri, alumina mu gawo limakhalapo kutentha kwakukulu, ndipo imapanga kapangidwe kake kamkati pansi pa kutentha kwakukulu pamene kukonzanso kwa kristalo kumakhala kokhazikika pa kutentha kwakukulu, kukana kuvala, magwiridwe antchito abwino osinthira kutentha kuphatikiza apo, kukhalapo kwa acidic ndi alkaline pakati ngati acid mu alkaline sing'anga, ndipo komwe kumatha kuchita ngati alkali mu acidic sing'anga. Chifukwa chake, chonyamulira cha chonyamulira cha alumina, chifukwa chake, chimakhala ndi chithandizo ndi kufalikira kwa zitsulo zamtengo wapatali zomwe zimapangitsa kuti kufalikira kwa pamwamba pa chitsulo mu kukula kwa tirigu wocheperako kumakhala kokhazikika, kosavuta kusonkhanitsa ndi kusungunula ndikofunikira kwambiri chifukwa aluminium oxide ya alumina, aluminiyamu patebulo ndi kusuntha, amapanga ma oxide ndikusiya dzenje, yokhala ndi void fraction yayikulu komanso malo ambiri osungira, imatha kukhazikika zigawo zoyambitsa malo ake amkati, ndipo imalola kufalikira pakati pa zoyambitsa ndi zinthu zonse. onetsani kuti alumina ili ndi ntchito yabwino kwambiri ngati chonyamulira cha catalyst.
