Hauv kev lag luam petrochemical, hydrotreating, hydrocracking, thiab ib puag ncig catalyst industries, catalyst txhawb cov ntaub ntawv ua lub luag haujlwm txiav txim siab hauv kev ua haujlwm catalyst. Pseudoboehmite yog cov khoom siv tseem ceeb rau kev tsim cov khoom siv alumina catalyst. Nws cov qauv pore, thaj chaw saum npoo, thiab qhov pore ntim ncaj qha cuam tshuam rau kev ua, kev xaiv, thiab kev pabcuam lub neej ntawm cov catalyst zaum kawg. Ntawm lawv,loj pore ntim pseudoboehmiteyog nce nqi thiab dav siv los ntawm catalyst manufacturers.
1. Siab dua Pore Volume txhim kho Active Hlau Loading Capacity
Cov kev ua ntawm catalysts feem ntau yog los ntawm active hlau Cheebtsam loaded nyob rau saum npoo ntawm cov kev them nyiaj yug, xws li Ni, Mo, Co, thiab W. Loj pore ntim pseudoboehmite muaj ib tug loj pore ntim thiab ntau tsim pore qauv, uas tso cai rau ntau active hlau Cheebtsam yuav tsum tau loaded, yog li txhim kho catalyst kev ua thiab cov tshuaj tiv thaiv efficiency.
Piv nrog rau cov pa pseudoboehmite, cov khoom ntim pore loj tuaj yeem ua tiav cov hlau tawg ntau dua nyob rau hauv tib lub sijhawm, ua kom cov catalysts ua tau zoo dua hauv hydrotreating, hydrodesulfurization, thiab hydrodenitrification tshua.
2. Txhim kho Molecular Diffusion thiab Reaction Efficiency
Hauv hydrocracking thiab residue hydrotreating txheej txheem, feedstock roj molecules kuj loj. Yog tias qhov catalyst pore loj me dhau, nws yuav cuam tshuam cov reactants los ntawm kev nkag mus rau hauv lub catalyst sab hauv, ua rau kom muaj kev tawm tsam thiab txo cov catalytic efficiency.
Loj pore ntim pseudoboehmite muaj qhov pore loj dua thiab tsim nyog ntau qhov pore loj faib, uas tuaj yeem:
Txo diffusion kuj
Txhim kho tus nqi diffusion ntawm reactants rau hauv catalyst pores
Ua kom cov catalyst siv efficiency
Txhim kho cov tshuaj tiv thaiv rau cov roj hnyav thiab cov molecules loj
Yog li ntawd, cov pore loj pseudoboehmite yog qhov tseem ceeb tshwj xeeb hauv hydrocracking catalysts, hydrodesulfurization catalysts, thiab hydrotreating catalysts.
3. Txhim kho Catalyst stability thiab kev pab lub neej
Thaum lub sij hawm ua hauj lwm, catalysts yog nquag mus rau pore blockage los ntawm carbon deposition thiab hlau deposition, uas ua rau catalyst deactivation. Vim qhov loj pore loj ntawmloj pore ntim pseudoboehmite, txawm tias coke los yog deposits tsim thaum lub sij hawm cov txheej txheem cov tshuaj tiv thaiv, lub pores yog tsis tshua muaj yuav tsum tau tag nrho blocked, yog li no ho expanding lub neej kev pab cuam ntawm lub catalyst.
Qhov no yog ib qho tseem ceeb heev rau refineries thiab tshuaj nroj tsuag vim hais tias lub sij hawm ntev lub catalyst hloov lub voj voog, tus nqi khiav hauj lwm ntawm cov nroj tsuag yuav qis dua.
4. Ntau qhov tsim nyog rau kev tsim cov chaw siab saum npoo Activated Alumina Carrier
Pseudoboehmite tuaj yeem hloov mus rau hauv activated alumina catalyst cab kuj tom qab tsim, ziab, thiab calcination. Loj pore ntim pseudoboehmite tseem tuaj yeem tswj tau:
Qhov chaw siab
Loj pore ntim
Zoo pore loj faib
High mechanical zog
Yog li ntawd, loj pore pseudoboehmite yog ib qho tseem ceeb raw khoom rau kev ua tau zoo -kev ua tau zoo alumina catalyst cab kuj.
Hais txog Zibo Xiangrun Environmental Engineering Co., Ltd.
Nrog ntau xyoo ntawm kev paub txog cov khoom siv alumina thiab ua tiav kev tswj hwm zoo, Zibo Xiangrun Environmental Engineering Co., Ltd. tuaj yeem muab cov pore loj ntim pseudoboehmite nrog siab purity, loj pore ntim, thiab ruaj khov zoo rau catalyst manufacturers. Lub tuam txhab tseem muab alumina catalyst carriers thiab lwm yam khoom alumina, muab kev daws teeb meem rau catalyst ntau lawm, pab cov neeg siv khoom txhim kho catalyst kev ua tau zoo thiab txo cov nqi tsim khoom.
