Hona jwale, tshebediso e ka sehloohong ya pseudo-boehmite ke thepa e tala bakeng sa ho lokisa alumina le sekhomaretsi bakeng sa catalyst e thata ho etsa kapa catalyst. Alumina e lokisitsweng ka ho besa pseudo-boehmite e na le sebaka se phahameng se ikgethang mme e sebediswa haholo e le catalyst le catalyst carrier indastering ya petrochemical.
1. e sebelisetsoang thepa e tala ea alumina ea nanometer
E 'ngoe ea TŠEBELISO ea bohlokoa ea pseudo-boehmite ke thepa e tala ea aluminium oxide. Ho latela litšobotsi tsa sebaka se seholo se ikhethileng, ts'ebetso e phahameng le ho hohela ka matla ha thepa e tala, e sebelisitsoe ho kopanya li-ceramic tsa sebopeho tse mocheso o phahameng joalo ka li-ceramic tsa aluminium nitride. Ho phaella moo, nano-Al2O3 e loketse haholo bakeng sa ho bentša lik'hemik'hale (CMP), ka nano-Al2O3 kaha likaroloana tse silang tse hlahisoang ke slurry ea CMP li ka sebelisoa moalong o bohareng oa ts'ebetso ea tlhahiso ea IC joalo ka lisebelisoa tsa wiring tsa semiconductor le thepa ea filimi joalo ka tungsten, aluminium, ho betla ha koporo, le khalase e tsoetseng pele ea optical, kristale ea quartz le ho bentša mahakoe a fapaneng.
Setšoantšo -Al2O3 se ka sebelisoa bakeng sa likaroloana tse khorofo tsa ho bentša ka mechine tsa lik'hemik'hale
2. Bakeng sa hydrogenation catalyst
E le ho fihlela litlhoko tsa tšebeliso ea mehloli ea peterole le oli e hloekileng, theknoloji e nang le hydrogenation e sebelisitsoe haholo, hydrogenation catalyst ke motheo oa theknoloji ea hydrogenation, e sebelisoang bakeng sa hydrogenation catalyst, gamma alumina carrier hangata e entsoe ka diaspore e tšesaane ka ho besa metsi, e na le sebaka se itseng sa bokaholimo, monyako le kabo ea li-pore tse fetoloang, bokaholimo bo na le setsi se fapaneng sa asiti. Matla a betere a mechini le botsitso ba mocheso, hammoho le litšobotsi tse theko e tlase.
Li-catalyst tsa litšoantšo lia hlokahala bakeng sa tlhahiso ea lihlahisoa tsa peterole
Indastering ea kajeno ea ho hloekisa oli le lik'hemik'hale, ho feta 90% ea ts'ebetso ea karabelo ea lik'hemik'hale e etsoa ka ts'ebetso ea catalytic, kahoo catalytic e fetohile senotlolo sa ho etsa ts'ebetso e ncha ea ho hloekisa le ea lik'hemik'hale, nts'etsopele ea sehlahisoa se secha. Indastering ea ho hloekisa oli, li-catalyst tse tiileng li sebelisoa hangata, tse entsoeng ka carrier le karolo e sebetsang. Carrier ke karolo e ikhethang ea catalytic e tiileng, e ka eketsang sebaka se itseng sa bokaholimo, ea ntlafatsa khanyetso ea mocheso le matla a mechini. Catalytic E SEBELISA mefuta e mengata ea catalyst, joalo ka: alumina, sieve ea limolek'hule, gel ea silica, gel ea silica, carbon e entsoeng le lefats'e la diatomaceous. Leha ho le joalo, bongata ba carrier ea alumina bo etsa karolo e fetang halofo ea kakaretso ea catalyst catalytic. Catalytic cracking (FCC) catalytic ke motheo oa ts'ebetso ea catalytic cracking. Jwalo ka oli e tala ea lefats'e e boima le e tlase, ho catalytic cracking thepa e tala e kopanyang oli e boima, oli e setseng e fetohile mokhoa o sebelisoang haholo oa ts'ebetso, kahoo ho hlokahala catalytic cracking (FCC) catalytic e tlameha ho ba oli e boima ea ho hasana ha limolek'hule tse kholo tsa lesoba le leholo, 'me lesoba le leholo bohareng le lokela ho ba le acid e lekaneng, e le ho ntlafatsa bokgoni ba ho petsoha ha catalyst ba metsoako ya macromolecular ka hara thepa e tala. Alumina e sebetsang e sebediswa hangata ho ntlafatsa matrix ya catalyst. Bophahamo bo boholo ba pore bo thusa ho hasana ha metsoako ya macromolecular ka hara dikarolwana tsa catalyst, ha sebaka se phahameng se ikgethang se thusa ho hasana ha tshepe e sebetsang, e le ho ntlafatsa tshebetso ya karabelo ya catalyst.
3. E sebelisoa e le sekhomaretsi
Sejari sa diaspore se tšesaane se sebelisoang e le moemeli oa tlamahano ha se na molemo feela ho bōpeng, se tla boela se ame ts'ebetso ea catalyst, bafuputsi ba catalyst ea flue gas denitration selective catalytic reduction Ce – Mn/TiO2 nakong ea ho kopanya diaspore e tšesaane e le moemeli oa tlamahano, ba fumane hore ha se feela ho ntlafatsa matla a mechini a li-catalyst, empa hape ho ntlafalitse catalyst e khethollang ea denitration surfactant.
4. lokisa sekoahelo sa -Al2O3
Mosebetsi oa ho koahela lera holim'a sekoahelo sa sekoahelo sa sekoahelo ke ho eketsa sebaka se itseng sa mokhoa o sebelisoang hangata, gamma alumina ke e 'ngoe ea thepa e sebelisoang haholo ea sekoahelo, e nang le sebaka se phahameng se ikhethileng, e thusang karolo e sebetsang kabong e sebetsang nakong ea ts'ebetso ea ho kenngoa, ho lokisoa ha sekoahelo sa gamma alumina se sebelisoang hangata bakeng sa sol ea pele ea AlOOH, sol ea alumina e tla ba diaspore e tšesaane e le thepa e tala, ho lokisoa, ka ho sebelisa mokhoa oa ho etsa acid peptization ho bonolo ho o laola, ho ka sebelisoa bakeng sa tlhahiso ea indasteri.
