Hydrotreing yog cov txheej txheem tseem ceeb hauv roj av ua kom zoo nkauj, ua kom tshem tawm cov impurities thiab txhim kho cov roj ua tau zoo. Cov catalysts siv nyob rau hauv hydrotrealing ua si lub luag haujlwm tseem ceeb hauv kev saib xyuas cov txheej txheem no. Ib qho ntawm lub hom phiaj tseem ceeb yog tshem cov leej faj, nitrogen thiab lwm cov feem cuam tshuam los ntawm ntau cov roj tsaj roj, xws li naphtha, nqus roj (vgo) thiab diesel. Kab lus no yuav muab qhov tob tob ntawm qhov tseem ceeb ntawmHydrotreing catalysts, tshwj xeeb nyob rau hauv hydrodesulfurization (HDS) ntawm Naphtha thiab Vgo thiab Hydrodenitricate (HDN) ntawm cov roj diesel.
Hydrotrice catalysts yog qhov tseem ceeb rau cov txheej txheem hydrofinishing vim tias lawv lub peev xwm los hloov pauv cov leej faj thiab nitrogen sulfide thiab ammonia cov ntawv. Qhov kev hloov dua siab tshiab no tau ua tiav los ntawm cov kev sib tw ntawm catalytic uas tshwm sim raws li qhov kub thiab txias thiab muaj cov xwm txheej siab. Ob qho uas paub zoo catalysts siv nyob rau hauv hydrotrealing yogGC-HP406thiabGC-HP448, uas yog tshwj xeeb tsim rau cov roj av sib txawv.
Nyob rau hauv naphtha, hydrodesulfurization yog cov kauj ruam tseem ceeb hauv hydrotreumeating txij li naphtha yog lub ntsiab pub rau kev tsim cov roj av. TusGC-HP406twj huamyog tshwj xeeb yog tsim los kom zoo txhawb kev tshem tawm ntawm cov leej faj tebchaw ntawm naphtha, kom ntseeg tau tias cov kev cai kawg thiab cov kev tshwj xeeb ib puag ncig. Cov catallyst plays lub luag haujlwm tseem ceeb hauv kev txhim kho cov roj uas muaj kev hloov pauv tag nrho ntawm cov sulphur-muaj cov kab ke rau hauv hydrogen sulfide.
Ib yam li ntawd, nyob rau hauv hydrotreing ntawm vggo thiab diesel, ob qho tib siHDS thiab HDNyog cov txheej txheem tseem ceeb.GC-HP448 catalystyog tshwj xeeb tsim los ua kom tau raws li cov dej num hydrotreuming ntawm vggo thiab diesel leb. Nws tau tshem tawm cov txiv lws suav thiab nitrogen sib xyaw, yog li kev txhim kho lub cetane naj npawb thiab tag nrho cov roj diesel. Ib qho ntxiv, cov catalyst yuav pab txo cov ncauj lus sulpur hauv VGO, uas yog qhov tseem ceeb los ntsib cov khoom lag luam Sulfur rau ntau yam khoom kawg vego, xws li dav hlau roj thiab diesel.
Catalysts siv nyob rau hauv hydrotreating yog engineered rau nthuav tawm cov haujlwm siab, xaiv thiab ruaj khov raws li kev ua haujlwm ua kom zoo dua ntawm cov txheej txheem refinery. Lawv tau tsim los los tiv thaiv cov paug thiab cov tshuaj lom uas yuav muaj nyob rau hauv cov pub dawb, kom muaj kev ncua ntev catalyst lub neej thiab kev ua tau zoo ib yam. Ib qho ntxiv, kev nce qib hauv catalyst technology tau coj mus rau kev loj hlob ntawm kev ua haujlwm nrog kev ua haujlwm, pab kom nce kev ua haujlwm tau zoo thiab raug nqi.
Hauv cov ntsiab lus xaus,Hydrotreing catalystsyog qhov tseem ceeb rau cov khoom siv tau thiab muaj kev vam meej ntawm cov khoom siv roj av muaj roj av zoo. Kev nce qib ntawm cov thev naus laus zis ntawm GC-HP406 thiab GC-HP406 thiab GC-HP406 thiab GC-HP448 tau tshaj tawm cov txheej txheem ntawm hydrotha thiab vgo thiab HDN ntawm diesel. Raws li qhov kev thov kom cov roj huv tseem nce ntxiv, lub luag haujlwm ntawm hydrorecting catalysts hauv kev tsim cov kev xav tau siab tsis tuaj yeem tsis muaj kev xav. Los ntawm kev tshawb fawb txuas ntxiv thiab kev tsim kho nyob rau yav tom ntej los txhim kho kev ua tau zoo ntawm hydrotreal catalacysts, yog li tsav lub tshuab kev lag luam rau ntau dua kev ua tau zoo thiab ua tau zoo.
