Hauv sulfur-kev lag luam rov qab, cov txheej txheem Claus tau siv dav. Txawm li cas los xij, txwv tsis pub los ntawm qhov sib npaug ntawm qhov sib npaug, qhov rov qab cov tshuaj tiv thaiv ntawm H₂S thiab SO₂ tsis tuaj yeem ua tiav kev hloov pauv ntawm hydrogen sulfide mus rau cov tshuaj sulfur. Txawm hais tias nrog kev ua kom zoo ntxiv ntawm kev ua haujlwm tsis tu ncua, tag nrho cov sulfur- rov qab ua haujlwm tau zoo los ntawm cov tshuaj tiv thaiv sib npaug. Sulfide hom tseem nyob hauv cov pa roj. Cov tuam txhab lag luam feem ntau yuav tsum tau txhim kho tus Tsov tus tw nyuaj - cov pa roj hydrogenation kom tau raws li ib puag ncig emission, uas ua rau cov peev nyiaj ntau dua thiab kev siv hluav taws xob ua haujlwm.
H₂S xaiv-oxidation-rau-sulfur technology rhuav tshem cov kev txwv ntawm Claus equilibrium thiab hloov kho cov txheej txheem los ntawm qhov kev xav ntawm cov tshuaj tiv thaiv mechanism. Tsis txhob cia siab rau qhov sib npaug ntawm qhov sib npaug ntawm H₂S thiab SO₂, cov thev naus laus zis no ncaj qha thiab xaiv oxidizes hydrogen sulfide rau hauv cov tshuaj sulfur, ua kom tiav H₂S kev hloov pauv hauv txoj kev xav. Txawm li cas los xij, cov txheej txheem tshuaj tiv thaiv muaj cov khoom sib xws nrog rau H₂S, O₂, sulfur vapor thiab dej vapor. Sib sib zog nqus- oxidation sab tshwm sim tuaj yeem tsim cov sulfur dioxide, uas ncaj qha txo qis cov tshuaj sulfur. Kev lag luam muaj peev xwm ntawm tag nrho cov txheej txheem hinges ntawm lub catalyst lub peev xwm rau cov kev taw qhia cov tshuaj tiv thaiv.
Hauv cov txheej txheem no, H₂S yog thawj zaug hloov mus rau hauv cov tshuaj sulfur, uas tuaj yeem raug oxidized ntxiv rau hauv SO₂. Txhawm rau ua kom muaj txiaj ntsig zoo sulfur- kev ua tau zoo, nws yog ib qho tseem ceeb kom ua kom cov tshuaj tiv thaiv tseem ceeb thiab txo qis tom qab sib sib zog nqus - oxidation sab tshwm sim. Lub catalyst yuav tsum txo qis sab-react probability over a wide temperature window, lav txaus H₂S hloov dua siab tshiab thiab siab selectivity los txwv SO₂ tsim. Lub caij no, cov khoom siv suab nrov xws li kev sib tsoo lub zog txaus thiab tus nqi qis qis yuav tsum tau hloov mus rau kev lag luam reactor loading thiab roj- ntws yaig rau ntev - lub sijhawm ua haujlwm ruaj khov.
Shandong Xunda TshuajKev lag luamGroup Co., Ltd. tau tsim muaj tswvcatalysts rau H₂S xaiv oxidation rau sulfur. Lub catalyst modulates cov tshuaj tiv thaiv- tus nqi sib piv thoob plaws kev ua haujlwm dav - qhov kub thiab txias, txwv kev sib sib zog nqus - oxidation ntawm sulfur los txiav SO₂ tiam, thiab sib npaug kev hloov pauv kev ua haujlwm thiab sulfur- kev xaiv ntau lawm. Nws yog haum rau sulfur- rov ua hauj lwm tej yam kev mob ntawm ntau yam sulfide- muaj roj qhov chaw nyob rau hauv refinery thiab thee- tshuaj industries.
Tau ntsib nrog kev nruj nruj thoob ntiaj teb cov qauv ib puag ncig, sulfur- cov chaw rov qab ua tsis tau tsuas yog ua raws li kev ua raws cai xwb, tab sis kuj tau ua kom zoo dua kev siv peev, kev siv hluav taws xob thiab cov txiaj ntsig kev lag luam los ntawm cov khoom siv sulfur. Txoj kev xaiv - txheej txheem oxidation muaj lwm txoj hauv kev daws teeb meem rau leej faj- cov phiaj xwm rov qab.
