Qhov sib txawv tseem ceeb ntawm hydrocracking thiab hydrotreating yog tias hydrocracking suav nrog kev hloov pauv ntawm cov dej kub npau npau rau hauv cov dej kub npau npau, hos hydrotreating suav nrog kev tshem tawm cov pa oxygen thiab lwm yam heteroatoms.
Hydrocracking thiab hydrotreating yog cov txheej txheem tseem ceeb hauv roj av refining. Ob txheej txheem no tuaj nyob rau hauv qeb ntawm hydroprocessing. Ntxiv mus, ob qho tib si ntawm cov txheej txheem no tshwm sim nyob rau hauv lub xub ntiag ntawm hydrogen gas. Txawm li cas los xij, muaj qhov sib txawv ntawm hydrocracking thiab hydrotreating raws li txoj cai thiab cov txheej txheem.
Hydrocracking yog dab tsi?
Hydrocracking yog txheej txheem ntawm kev hloov cov dej kub npau npau rau hauv cov dej npau npau qis. Qhov ntawd txhais tau tias; cov reactants ntawm hydrocracking cov tshuaj tiv thaiv yog cov khoom ntawm cov roj av muaj cov ntsiab lus kub kub, thiab cov khoom yog cov tebchaw uas muaj cov ntsiab lus boiling tsawg. Tsis tas li ntawd, cov txheej txheem no tseem ceeb heev vim tias cov khoom qis qis yog cov khoom muaj txiaj ntsig ntau dua, uas suav nrog roj av, roj av, roj av, roj av, thiab lwm yam.

Cov txheej txheem ntawm hydrocracking yog lub npe xws li vim tias kev tawg ntawm cov molecules loj tshwm sim nyob rau hauv muaj cov pa roj hydrogen. Feem ntau, hydrocracking yog ua nyob rau hauv cov mob hnyav. Nws yog vim hais tias cov reactants ntawm hydrocracking feedstock raug rau lub reactor kub rau lub sij hawm ntev.
Hydrotreating yog dab tsi?
Hydrotreating yog txheej txheem ntawm kev tshem tawm cov tsis xav tau ntawm cov khoom siv roj av. Nws yog ib qho tseem ceeb hauv kev tsim cov roj zoo. Ntxiv mus, cov khoom tshem tawm ntawm cov roj av muaj xws li oxygen, sulfur, nitrogen, hlau, thiab lwm yam. Cov no yog impurities nyob rau hauv cov roj av feem. Nws yog ib qho tseem ceeb heev kom tshem tawm cov kab mob no vim tias lawv ua rau muaj kev puas tsuaj rau cov khoom siv, catalysts, zoo ntawm cov khoom kawg, thiab lwm yam. Hydrotreating yog ua ua ntej hydrocracking los tiv thaiv cov catalyst los ntawm cov kab mob.
Qhov txawv ntawm Hydrocracking thiab Hydrotreating yog dab tsi?
Muaj ob hom kev ua dej raws li hydrocracking thiab hydrotreating. Qhov sib txawv tseem ceeb ntawm hydrocracking thiab hydrotreating yog tias hydrocracking suav nrog kev hloov pauv ntawm cov dej kub npau npau rau qis qis, hos hydrotreating suav nrog kev tshem tawm cov pa oxygen thiab lwm yam heteroatoms.
Thaum xav txog qhov tseem ceeb ntawm txhua tus txheej txheem, hydrocracking yog qhov tseem ceeb kom tau txais cov khoom muaj txiaj ntsig zoo xws li roj av, roj av, roj av, thiab lwm yam thaum hydrotreating tseem ceeb kom tshem tawm cov kab mob ntawm cov khoom noj rau hydrocracking.
Cov hauv qab no qhia txog qhov sib txawv ntawm hydrocracking thiab hydrotreating.
Summary – Hydrocracking vs Hydrotreating
Yeej, muaj ob hom hydroprocessing li hydrocracking thiab hydrotreating. Qhov sib txawv tseem ceeb ntawm hydrocracking thiab hydrotreating yog tias hydrocracking suav nrog kev hloov pauv ntawm cov dej kub npau npau rau qis qis, hos hydrotreating suav nrog kev tshem tawm cov pa oxygen thiab lwm yam heteroatoms.
