Hydrotreing catalystsUa si lub luag haujlwm tseem ceeb hauv kev kho kom zoo ntawm cov roj av, tshwj xeeb hauv hydrodesulfurization (HndsNtawm naphtha, nqus roj (Veggo) thiab ultra-qis sulfur diesel (Ulsd). Cov catalysts yog qhov tseem ceeb rau kev tshem cov leej faj, nitrogen thiab lwm yam kev cuam tshuam los ntawm cov roj av crude cred thiab ib puag ncig ntawm cov khoom kawg. Kom nkag siab qhov tseem ceeb ntawmHydrotreing catalysts, nws yog ib qho tsim nyog los pab rau hauv lub tswvyim ntawm hydroretreating thiab lub luag haujlwm ntawm catalysts hauv cov txheej txheem.
Dab tsi yog hydroreting catalyst?
Hydrotreing catalystS yog tshuaj yeeb uas txhawb nqa cov tshuaj lom neeg muaj feem cuam tshuam nrog hydrotreating ntawm cov roj tsaj roj. Hydrotreing yog hais txog ib pawg ntawm cov txheej txheem catalytic cuam tshuam nrog kev siv hydrogen kom tshem tawm impurities thiab txhim kho qhov zoo ntawm ntau cov roj av roj av. Cov hom tseem ceeb ntawmhydroprocessing suav nrog hydroreing, Hydrocacking, thiabhauv hydrofinishing, txhua qhov uas yuav tsum tau ua rau cov tshuaj tua kab tshwj xeeb rau cov tshuaj tiv thaiv.
Nafhatha HydrotReating cuam tshuam nrog cov leej faj, nitrogen thiab lwm yam impurities kom tau raws li ib puag ncig txoj cai nruj thiab txhim kho lub octane zoo ntawm cov khoom. Catalysts siv nyob rau hauvnaphtha hydrotriceFeem ntau yog raws li cov hlau me xws li cobalt, molybdenum thiab npib tsib xee tau txais kev txhawb nqa ntawm alumina lossis lwm cov khoom siv siab thaj tsam. Cov catalysts txhawb hydrogenation hydrogenation thiab desulfurization los tsim cov khoom siv qis, siab octane naphtha haum rau blending mus rau hauv roj av.
VGO HDS
Lub Tshuab Nqus Tsev Roj(VGO) yog ib qho tseem ceeb pub rau ntau yam dej ntws, suav nrog fluidized txaj catalytic cracking (FCC) thiab hydrocacking. Txawm li cas los xij, vgo feem ntau muaj qib sulfur thiab nitrogen, uas yuav tsum tau txo kom tau raws li cov khoom lag luam specifications. Hydrotreating catalysts tsim tshwj xeeb rauVGO HDSyog ua tib zoo tsim los tiv thaiv kev ua haujlwm hnyav thiab txhawb nqa kev tshem tawm cov leej faj thiab nitrogen sib xyaw, ua kom huv si vego rau kev ua ntxiv.
Vim yog nruj emission qauv, ultra-qis sulfur diesel (Ulsd) yog cov khoom tseem ceeb hauv kev kho kom zoo nkauj niaj hnub. Qhov ntau lawm ntawm ulsd koom nrog hydrotreeting kom txo cov lus faj sulfur mus rau ultra-theem qis. Ulsd HDS Catalysts yog xaiv siab rau Desulfurization thaum minimizing hydrogenation ntawm lwm cov khoom siv tau zoo thiab kev cai tswj cov kev cai.
Lub luag haujlwm ntawm catalyst
Hauv tag nrho cov txheej txheem hydrotreate, catalysts ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa cov kev xav tau thaum tswj lub sijhawm ntev ruaj khov thiab ua si. Qhov kev xaiv ntawm cov txheej txheem catalyst, suav nrog cov hom thiab cov khoom siv cov khoom siv txhawb nqa, cuam tshuam rau cov kev ua tau zoo thiab xaiv tau ntawm cov khoom siv hydrotrice. Tsis tas li ntawd, kev nce qib hauv catalyst Technology, xws li kev txhim kho cov qauv tshiab-txhawb nqa thiab txhim kho cov ntaub ntawv txhawb nqa tshiab thiab kev ua haujlwm ntev ntawm hydroprocessing catalysts.
Hauv kev xaus
Hydrotreing catalystsYog kev sib xyaw ua lag luam kev nqus tsev ntxhua khaub ncaws, cov khoom lag luam roj ntau dua. Raws li cov kev cai ib puag ncig dhau los ua nruj dua, qhov xav tau ntawm cov catalysive thiab kev xaiv cov txheej txheem hauv hydrotrice kev ua haujlwm txuas ntxiv mus. Kev tshawb fawb txuas ntxiv thiab kev txhim kho ua haujlwm hauv cov cuab yeej thev naus laus zis ua ntxiv txhawm rau txhim kho cov kev ua tau zoo thiab kev ruaj ntseg ntawm cov phooj ywg zoo ntawm cov roj thiab petrochemicals.
