Hydrotreating yog txheej txheem tseem ceeb hauv cov khoom siv roj av refining, aiming tshem impurities thiab txhim kho roj zoo. Cov catalysts siv hauv hydrotreating ua lub luag haujlwm tseem ceeb hauv kev ua kom txoj haujlwm no. Ib lub hom phiaj tseem ceeb ntawm hydrotreating yog tshem cov sulfur, nitrogen thiab lwm yam impurities los ntawm ntau cov roj crude feem, xws li naphtha, nqus roj (VGO) thiab diesel. Kab lus no yuav muab qhov tob tob saib qhov tseem ceeb ntawmhydrotreating catalysts, tshwj xeeb hauv hydrodesulfurization (HDS) ntawm naphtha thiab VGO thiab hydrodenitrification (HDN) ntawm diesel roj.
Hydrotreating catalysts yog qhov tseem ceeb rau cov txheej txheem hydrofinishing vim tias lawv muaj peev xwm hloov pauv tsis xav tau leej faj thiab nitrogen tebchaw rau hauv lawv cov ntawv hydrogen sulfide thiab ammonia. Qhov kev hloov dua siab tshiab no tau ua tiav los ntawm cov tshuaj tiv thaiv catalytic uas tshwm sim nyob rau hauv qhov kub thiab txias. Ob lub npe nrov catalysts siv hauv hydrotreating yogGC-HP406thiabGC-HP448, uas yog tsim tshwj xeeb rau cov roj crude sib txawv.
Nyob rau hauv cov ntaub ntawv ntawm naphtha, hydrodesulfurization yog ib kauj ruam tseem ceeb hauv hydrotreating vim naphtha yog lub ntsiab feedstock rau zus tau tej cov roj av. CovGC-HP406catalystyog tsim tshwj xeeb los txhawb kev tshem tawm cov sulfur compounds los ntawm naphtha, kom ntseeg tau tias cov khoom kawg ua raws li cov kev cai nruj ib puag ncig thiab cov lus qhia zoo. Lub catalyst plays lub luag haujlwm tseem ceeb hauv kev txhim kho tag nrho cov roj av zoo los ntawm kev txhawb nqa kev hloov pauv ntawm sulfur-muaj cov tebchaw rau hauv hydrogen sulfide.
Ib yam li ntawd, hauv hydrotreating ntawm VGO thiab diesel, ob qho tib siHDS thiab HDNyog cov txheej txheem tseem ceeb.GC-HP448 catalystyog tsim tshwj xeeb kom tau raws li cov kev cai hydrotreating ntawm VGO thiab diesel fractions. Nws tshem tawm cov sulfur thiab nitrogen tebchaw, yog li txhim kho tus lej cetane thiab tag nrho cov roj diesel zoo. Tsis tas li ntawd, cov catalyst pab txo cov ntsiab lus ntawm cov sulfur hauv VGO, uas yog ib qho tseem ceeb kom ua tau raws li cov ntsiab lus ntawm cov sulfur rau ntau yam VGO-derived kawg cov khoom, xws li dav hlau roj thiab diesel.
Catalysts siv nyob rau hauv hydrotreating yog engineered los ua kom pom kev ua haujlwm siab, kev xaiv thiab kev ruaj ntseg raws li kev ua haujlwm hnyav ntawm cov txheej txheem refinery. Lawv tau tsim los tiv thaiv cov kab mob thiab cov tshuaj lom uas muaj nyob hauv cov khoom noj, ua kom lub neej ntev catalyst thiab kev ua haujlwm zoo ib yam. Tsis tas li ntawd, kev nce qib hauv catalyst thev naus laus zis tau ua rau kev txhim kho cov catalysts nrog kev tiv thaiv kom tsis muaj zog, pab txhawb kev ua haujlwm thiab kev siv nyiaj txiag.
Hauv cov ntsiab lus,hydrotreating catalystsyog qhov tseem ceeb rau kev ua tau zoo thiab ruaj khov ntawm cov khoom siv roj av zoo. Kev nce qib ntawm cov tshuab catalyst sawv cev los ntawm GC-HP406 thiab GC-HP448 tau txhawb nqa kev ua kom zoo ntawm cov txheej txheem hydrotreating, tshwj xeeb tshaj yog hauv HDS ntawm naphtha thiab VGO thiab HDN ntawm diesel. Raws li qhov kev thov rau cov roj huv huv txuas ntxiv zuj zus, lub luag haujlwm ntawm hydrotreating catalysts hauv kev tsim cov roj ua haujlwm siab uas ua tau raws li qhov xav tau ntawm ib puag ncig tsis tuaj yeem kwv yees. Los ntawm kev tshawb fawb txuas ntxiv thiab kev tsim kho, muaj kev cog lus zoo rau yav tom ntej txhawm rau txhim kho kev ua tau zoo ntawm hydrotreating catalysts, yog li tsav lub refining kev lag luam mus rau ntau dua sustainability thiab efficiency.
