Catalanst Cov Nqa Khoomyog cov ntaub ntawv tseem ceeb rau kev thauj cov khoom siv ua haujlwm, uas cuam tshuam ncaj qha, kev ruaj khov thiab lub neej ntawm cov ntsiab lus ntawm alumina cov cab kuj no yog.
Qhov zoo ntawm alumina catalyst cov nqa khoom
1.} Cov chaw siab tshwj xeeb thaj chaw
Alumina muaj thaj chaw thaj chaw tshwj xeeb, uas tuaj yeem muab cov khoom siv catalysulfurization, Li no cov hlau lossis hlau oxide cov tshuaj tivthaiv thiab hlau oxide cov khoom siv thiab hlau oxide} Kev ua tau zoo .
2.} zoo heev thermal ruaj khov
Alumina tseem tuaj yeem tswj cov txheej txheem ruaj khov ntawm cov txheej txheem kub thiab ua kom yooj yim rau lwm tus neeg nqa khoom, uas tau ua haujlwm ntev dua, uas tau ua haujlwm ntev ntawm lub neej ntawm catalys {2.
3. zoo thev naus laus zis lub zog
Muaj cov txheej txheem catalytic yuav tsum muaj cov neeg nqa khoom muaj kev kub siab thiab tuaj yeem tiv thaiv kev kub ntxhov thiab muaj peev xwm tiv thaiv kev kub ntxhov thiab cov teeb meem pullast.
4.} Adjustable Pore qauv thiab Pore loj faib
Los ntawm kev hloov cov txheej txheem npaj, lub pore loj thiab porosity ntawm cov reactans zoo, macroporous aluminess {.
5. Adjustable Nto Acidity thiab Alkalinity
Lub deg ntawm alumina muaj lewis acid thiab bronsted acid thiab alkalinity tuaj yeem hloov kho los ntawm doping, ua rau nws haum rau kev sib txawv catalytic cov kev tawm tsam {}}} Piv txwv:
• Acc acidic catalysis yuam, alkane tawg, dej haus dej haus rau Olefins .
• Cov Txheej Txheem Yooj Yim: Lub zog txhos caug Cov tshuaj tiv thaiv kev tiv thaiv .
6.} Kev Tshuaj Lom Ua Phem thiab Ruaj Ntseg
Alumina yog tshuaj tsis ruaj khov nyob rau hauv feem ntau cov tshuaj tiv thaiv cov tshuaj tiv thaiv kab mob, thiab tsis nquag rau sab kev sib xyaw nrog cov txheej txheem catalynion .
7.} kev kawm adsorption zoo adsorption zoo
Lub deg ntawm alumina yog nplua nuj nyob rau hauv hydroxyl pawg thiab cov tuaj yeem hloov kho cov tshuaj tua kab mob molecules thiab sib piv thiab txhim kho kev ua haujlwm catalanytic ntawm cov khoom siv hluav taws xob {}}
8.} kev cuam tshuam muaj zog nrog cov khoom siv nquag
Alumina tuaj yeem tsim cov kev sib txuam muaj nrog ntau cov hlau lossis oxides, tiv thaiv cov khoom siv tsis muaj peev xwm thiab kev txhim kho cov catalyst lub peev xwm tiv thaiv sintering .
{{0 {}} tus nqi qis thiab kev lag luam yooj yim
Alumina raw khoom siv dav dav thiab cov txheej txheem npaj tau muaj thiab muaj txiaj ntsig ntxiv rau lwm cov nqa khoom, nws muaj qhov tsim nyog rau cov loj tsim ntau lawm.
10. ib puag ncig ib puag ncig
Alumina yog tsis muaj tshuaj lom thiab tsis muaj mob, thiab yog qhov yooj yim rov qab lossis muab pov tseg ntawm cov kev tsim kho ntsuab thiab kev txhim kho kom ruaj khov.
Lub ntsiab
Alumina catalyst cov nqa khoomtau dhau los ua cov ntaub ntawv tsis tseem ceeb hauv kev lag luam catalysis vim yog cov khoom siv hluav taws xob zoo nkauj, muaj cov tshuaj tiv thaiv zoo dua qub, muaj cov tshuaj tiv thaiv zoo nkauj heev, kev tiv thaiv ib puag ncig thiab cov tshuaj zoo.
