Cov kua dej catalytic cracking yog ib qho ntawm cov txheej txheem hloov pauv tseem ceeb tshaj plaws siv hauv cov roj av refineries. Nws yog dav siv los hloov cov ntsiab lus kub kub, siab molecular hnyav hydrocarbon feem ntawm cov roj av crude rau hauv cov roj av muaj txiaj ntsig, roj olefinic, thiab lwm yam khoom.
Koj txhais li cas los ntawm catalytic tawg?
Catalytic cracking yog txheej txheem tseem ceeb hauv kev lag luam roj uas roj av vapor dhau los ntawm lub txaj qis ntawm cov catalyst, uas ua rau cov ntu hnyav dua rau 'kav' ua kom sib dua. cov khoom muaj nqis. Hauv kev lag luam petrochemicals lawv tau siv los ua polyolefins ntawm qhov loj heev.
Yuav ua li cas hauv catalytic tawg?
Chav lossis catalytic degradation (cracking) yog hais txog kev degradation ntawm cov yas los ntawm chav lossis lub catalyst. Nyob rau hauv catalytic cracking khoom catalysts zoo hloov cov yas rau hauv cov roj ua kua, muab cov seem sib dua piv rau thermal cracking.
Catalytic cracking quizlet yog dab tsi?
Catalytic tawg. tawg ntev saw HCs rau hauv me me molecules siv lub catalyst.
Qhov txawv ntawm thermal thiab catalytic cracking yog dab tsi?
Qhov sib txawv tseem ceeb ntawm thermal cracking thiab catalytic cracking yog qhov thermal cracking siv lub zog hluav taws xob rau kev tawg ntawm cov tebchawwhereas catalytic cracking muaj catalyst kom tau cov khoom.
