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.

Yuav ntsuas oxidative kev nyuaj siab li cas?
Kev ntxhov siab Oxidative tuaj yeem ntsuas tsis ncaj los ntawm ntsuas qib DNA / RNA kev puas tsuaj, lipid peroxidation, thiab protein oxidation / nitration, es tsis yog ntsuas ncaj qha ntawm cov pa oxygen reactive. Cov cim oxidative kev ntxhov siab no muaj kev ruaj khov dua li cov pa oxygen reactive .
Cov kab mob twg muaj cov oxidative enzymes?
PEROXISOMES yog cov organelles me uas muaj oxidative enzymes. Peroxisomes muaj npe vim tias lawv siv cov pa oxygen molecular los tshem cov hydrogen atoms los ntawm cov organic molecules tshwj xeeb hauv cov tshuaj tiv thaiv oxidation uas ua rau hydrogen peroxide (H2O2) .
Rau qhov kev ua ub no yog cov txheej txheem oxidative feem ntau siv?
Cov kab mob oxidative, thawj qhov chaw ntawm ATP thaum so thiab thaum lub sijhawm ua haujlwm qis, siv feem ntau carbohydrates thiab rog li substratesUa raws li qhov pib ntawm kev ua, raws li kev siv ntawm Kev tawm dag zog nce ntxiv, muaj kev hloov pauv hauv substrate nyiam los ntawm cov rog mus rau carbohydrates .
Puas yog oxidative decarboxylierung?
Pyruvate decarboxylation lossis pyruvate oxidation, tseem hu ua qhov txuas cov tshuaj tiv thaiv, yog kev hloov pauv ntawm pyruvate rau hauv acetyl-CoA los ntawm cov enzyme complex pyruvate dehydrogenase complex. Puas yog entsteht bei der oxidativen Decarboxylierung?
Thaum oxidative phosphorylation atp synthase yog powered los ntawm?
theem kawg ntawm oxidative phosphorylation yog ua los ntawm ATP synthase, ATP-synthesizing sib dhos uas tau tsav los ntawm ntws ntawm protons rov qab rau hauv mitochondrial matrix. Cheebtsam ntawm no zoo kawg nkaus enzyme tig raws li ib feem ntawm nws catalytic mechanism .
