Activated Alumina Catalyst Carrier

Activated Alumina catalyst carriers tuaj yeem ua raws li cov neeg siv khoom xav tau.Cov catalyst cab kuj tuaj yeem tsim nyob rau hauv ntau yam morphology, lub zog, crystalline zoo, tshwj xeeb thaj chaw, pore ntim, pore loj faib, deg acid thiab lub zog lub zog. Xws li kheej kheej, kem thiab pob zoo li tus, nrog lub zog 10-200 N / pc.Lub crystalline daim ntawv muab faib ua alumina trihydrate, alumina hydrate,ρ-AL₂O₃, - AL₂O₃, -AL₂O₃, qhov ntim tshwj xeeb. tuaj yeem ncav cuag 350 m² / g thiab 0.7 cm³ / g.

Nws yog dav siv nyob rau hauv zus tau tej cov catalysts los ntawm iso-impregnation thiab tshaj-impregnation txoj kev.
Cov hlau tseem ceeb thauj khoom ntawm nws xws li kub, nyiaj, platinum, palladium, rhodium, iridium, thiab cov hlau hloov pauv hlau, manganese, tooj liab, zinc, thiab lwm yam tuaj yeem tawg tau zoo heev ntawm cov nqa khoom.
Activated alumina catalyst carriers yog hmoov dawb los yog tsim alumina khoom, uas yog cov khoom siv catalyst tshaj plaws. Sawb thiab spherical alumina feem ntau yog siv los ua catalyst cab kuj nyob rau hauv lub txaj ruaj reactor thiab microsphere alumina carriers feem ntau yog siv nyob rau hauv fluidized txaj reactor.Nws tseem tuaj yeem ua rau tshwj xeeb - cov cab kuj xav tau rau cov txheej txheem catalytic tshwj xeeb, xws li columnar, clover, honeycomb, thiab lwm yam.

Peb lub Hoobkas muaj cov cuab yeej tsim khoom tiav, kev tshuaj xyuas thiab kev soj ntsuam, kev tiv thaiv ib puag ncig- cov chaw kho mob, thiab cov txheej txheem tsis pub lwm tus paub hauv catalyst ua los tiv thaiv kev lag luam zais cia rau cov neeg siv khoom.Catalysts tuaj yeem kho raws li cov neeg siv khoom xav tau.Peb muaj ntau cov kab ntau lawm, suav nrog cov kab ntau lawm, impregnation 3} ntau lawm kab inetrusion, ntau lawm { kab, thiab ntau yam khoom siv xws li sib tov tshuab, kneading tshuab, dov tshuab, extrusion tshuab, mesh siv tshuab ziab khaub ncaws, teb kiln, qhov cub, mesh siv kiln, cov menyuam kiln, thiab lwm yam., uas tuaj yeem ua tau raws li qhov xav tau sib txawv.

1. Q: Dab tsi yog qhov tshwj xeeb ntawm thaj chaw ntawm koj cov Activated Alumina catalyst carriers? Qhov pore loj faib li cas?
A: Qhov chaw tshwj xeeb ntawm peb cov pa - hom activated alumina carriers feem ntau yog nyob rau hauv thaj tsam ntawm 280-350 m² / g. Nws tuaj yeem hloov kho raws li cov neeg siv khoom xav tau (piv txwv li, thaj chaw tshwj xeeb tuaj yeem ncav cuag ntau dua 380 m² / g). Lub pore loj faib yog concentrated ntawm 5-15 nm (nrog mesopores yog lub ntsiab tivthaiv), uas yog haum rau lub siab dispersion loading ntawm feem ntau hlau active Cheebtsam (xws li Ni, Co, Mo, Pt, thiab lwm yam). Rau cov tshuaj molecule loj (xws li hydrofining ntawm cov roj hnyav), peb tuaj yeem muab cov khoom nthuav dav (nrog pore diameters ntawm 15–30 nm). Peb tuaj yeem muab koj daim ntawv qhia BET yog tias koj xav tau

2. Q: Lub zog compressive yog dab tsi? Nws puas yuav hmoov thaum thauj khoom lossis ua haujlwm?
A: Lub zog ib leeg ntawm peb cov khoom siv hluav taws xob ua kom lub cev muaj zog ntau dua lossis sib npaug ntawm 80 N / gram (rau Φ3-5mm specifications), thiab radial crush lub zog ntawm cov khoom siv strip ntau dua lossis sib npaug rau 150 N / cm. Qhov no yog ntau dua li cov qauv kev lag luam (HG / T 3927 yuav tsum Ntau dua lossis sib npaug li 60 N / gram). Nrog rau kev ua kom zoo molding thiab tua cov txheej txheem, cov khoom yog ntom thiab hnav-resistant. Lawv tau ua haujlwm tsis tu ncua hauv loj- cov chaw ua kom zoo nkauj rau ntau dua 3 xyoos yam tsis muaj qhov pom tseeb.

3. Q: Nws puas yuav hloov pauv thiab deactivate thaum kub kub? Qhov kub siab tshaj plaws uas nws tuaj yeem siv tau yog dab tsi?
A: Tus qauv -Al₂O₃ qhib Alumina catalyst cab kuj tuaj yeem siv ruaj khov ntawm Tsawg dua lossis sib npaug li 600℃. Yog tias qhov ntsuas kub ua haujlwm siab tshaj 650 degree, peb pom zoo kom siv cov cua sov- ruaj khov hloov kho alumina (doped nrog La, Si, thiab lwm yam), uas tuaj yeem nce qhov kub thiab txias ntawm theem hloov mus rau saum 800 degree, cuam tshuam qhov poob ntawm thaj chaw tshwj xeeb. Qee cov neeg siv khoom tau ua tiav nws nyob rau hauv bypass system ntawm catalytic cracking regenerators.
