Cov txheej txheem hydrotreating residue-catalyst raw khoom pseudo boehmite

Cov yam ntxwv ntawm cov txheej txheem hydrotreating residue cov txheej txheem hydrotreating residue nrog lub txaj ruaj khov tau kawm thiab sau luv luv, thiab cov yam ntxwv hauv qab no tau sau luv luv: Ua ntej, cov tshuaj tiv thaiv sib txawv lossis cov khoom sib txawv ntawm tib lub txaj muaj qhov sib txawv ntawm 1) hydrotreating reaction yog exothermic reaction, hauv lub reactor kev lag luam, qhov kub nce hauv tib lub txaj, lub txaj txheej 2) qhov kub qis dua yog cov tshuaj tiv thaiv siab dua hauv thawj qhov chaw hauv lub txaj sab saud lossis thawj lub txaj tshuaj tiv thaiv, thiab cov khoom tiv thaiv ntawm qab ntawm lub txaj lossis tom qab lub txaj tshuaj tiv thaiv 3) lub txaj sab saud reactant concentration siab dua, thiab lub txaj txheej hauv qab reactant concentration qis lossis lub txaj sab saud reaction hloov pauv siab dua, qhov thauj khoom loj dua 4) hydrotreating reaction thiab tsim hydrogen sulfide thiab ammonia, hydrogen noj vim li cas lub txaj sab saud thiab hauv qab txheej ntawm H2 concentration ntawm H2S thiab NH3 sib txawv thib ob, cov roj seem muaj ntau yam tsis huv thiab cov khoom tsis zoo, nws qhov nruab nrab molecular hnyav, viscosity siab, ua rau kev ua haujlwm tsis zoo, catalyst deactivation, yog li cov txheej txheem hydrotreating residue ua haujlwm cov xwm txheej xav tau, siab siab thiab kub, qhov chaw ceev qis thib peb, residue tsim nyob rau hauv Cov txheej txheem hydrogenation ntawm lub txaj ruaj khov muaj ntau cov coke thiab hlau sulfide thiab lwm yam khoom khov kho, qhov kev tso cov khoom khov kho hauv lub txaj yuav ua rau qhov sib txawv ntawm lub txaj nce ntxiv kom txog thaum ncav cuag qhov txwv tsim, lub cuab yeej raug yuam kom kaw. Plaub, cov txheej txheem hydrotreating seem yuav tsum tau txais cov txheej txheem catalyst ua ke.
