Ntawm cov txheej txheem desulfurization, cov txheej txheem oxidative desulfurization (ODS) yog cog lus kom ua tiav cov ntsiab lus qis heev thiab zero sulfur ntawm cov rojHauv cov txheej txheem no, sulfur compounds hloov mus rau qhov sib thooj sulfone los ntawm cov catalyst thiab nyob rau hauv muaj cov oxidant.
Vim li cas desulphurization tseem ceeb?
Cov txheej txheem no yog qhov tseem ceeb ntawm kev lag luam thiab ib puag ncig qhov tseem ceeb vim lawv muab ntau cov sulfur siv hauv kev lag luam (Claus txheej txheem thiab kev sib cuag), cov tshuaj tsis muaj sulfur uas tuaj yeem txwv tsis pub. siv rau hauv ntau cov txheej txheem catalytic, thiab tseem txo qis kev tso tawm cov tshuaj lom sulfur rau hauv …
CoMo catalyst yog dab tsi?
Cov CoMo hydrogenation catalysts hloov lwm yam kab mob uas tseem tshuav tawm ntawm Claus seem mus rau H2S ua ntej nkag mus rau amine tail gas seem rau kev kho zaum kawg.
Tus catalyst twg yog siv hauv hydrodesulfurization?
Ruthenium disulfide (RuS2) tshwmlos ua ib qho tseem ceeb tshaj plaws catalyst, tab sis binary ua ke ntawm cob alt thiab molybdenum kuj muaj zog heev. Hauv kev xyaum, feem ntau HDS units hauv roj av refineries siv catalysts raws li cob alt-hloov molybdenum disulfide (MoS2) ua ke nrog me me ntawm lwm yam hlau.
Dab tsi catalyst siv hauv hydrotreating?
Txawm li cas los xij, hlau oxides, uas yog, alumina-txhawb hlau sulfidesyog, los ntawm qhov deb, feem ntau siv catalysts rau hydrotreating. Lawv muaj tus nqi qis dua, muaj kev tiv thaiv ntau dua rau cov impurities feem ntau muaj nyob rau hauv cov khoom siv pov tseg thiab tso cai rau kev sib koom ua dej ntawm cov lipids thiab cov roj av hauv cov chaw refinery uas twb muaj lawm.
