Dab tsi yog Claus catalyst?

Nyob rau hauv cov roj, nkev ua thiab thee chev rog kev lag luam, cov khoom siv paug tsis zoo tab sis kuj tseem muaj kev phom sij hauv cheeb tsam tab sis kuj tseem dav siv hauv kev lag luam, thiab cov tseem ceeb ntawm cov txheej txheem no yogClaus catalyst.

Cov txheej txheem Claus yog qhov paub tab Technology rau hloov mus rau hauv Elemental Sulphur, uas feem ntau suav nrog ob theem:

1.} Thermal tiv thaiv theem: h₂s yog ib nrab hlawv hauv kev sib txuas hluav taws xob kom tsim sulfur dioxide {}}

3h2s +32} O2} {{{{{}} {{{{{{{{16} {16} {16} {16} {16} {16}2+2 h25

2.} Cov lus qhia kev cuam tshuam nrog kev ua kom dhau ntawm qhov kev txiav txim ntawm kev ua ntawm cov sulphur .

2h2s + So2 → 38s 8+2 h2o2h2s + So2 → 83} {{

Tus Sulfur Rov Qab Tus Nqi ntawm cov txheej txheem no tuaj yeem ncav cuag 95% ~ 99%, thiab kev ua tau zoo ntawm cov tshuaj tiv thaiv kev ua tau zoo thiab sulfur tawm los .

Lub luag haujlwm tseem ceeb ntawm claus catalyst yog kom nrawm dua ntawm kev hloov pauv hloov pauv ntawm sulphur {{} Cov catalals zoo tshaj plaws yuav tsum muaj cov yam ntxwv hauv qab no:

• Cov kev ua haujlwm siab heev: nce cov tshuaj tiv thaiv cov tshuaj tiv thaiv thiab cov khoom txo qis {}}

• Zoo thermal stability: Haum rau qhov kev kub ntxhov ntawm Claus cov tshuaj tiv thaiv .

• anti-anti-anti-anti-anti-anti-anti-anti-anti-cuam tshuam nrog cov dej tsis huv xws li cov dej dej, hydrocand, organic sulfur tebchaw.

• Muaj zog txhua yam: kom tsis txhob cem breakal liam vim tias kev hloov Airflow lossis qhov kub hloov hloov .

Claus catalysts yog siv dav hauv:

• Cov ntoo ntuj uas muaj cov nroj tsuag uas muaj ntuj muaj roj: kho cov roj acidic uas muaj cov pa roj acidic uas muaj .

• Kev Ua Ntawv Teev Tseg: Kom rov qab los ntawm cov txiv lws suav tsim tawm thaum ua cov roj .

• Kev Lag Luam Kev Lag Luam Hluav Taws Xob: kom Purifation Sulfides hauv cov roj av roj av lossis coke cub roj roj .

• Kev Kho Mob Or Cheebtsam los: Txhawm rau txo cov pa roj sulphur hauv cov roj muaj roj kom tau raws li ib puag ncig cov kev cai.

• Txoj kev tsim kho tshiab: Tshem cov sulfate lossis carbon tso nyiaj los ntawm kev siv roj kub kom txo tau roj kub.

• Hloov lub voj voog: feem ntau 3-5}} xyoo, nyob ntawm cov txheej txheem cov xwm txheej thiab hom catalyst.

Claus catalystyog qhov tseem ceeb ntawm Claus cov txheej txheem . los ntawm kev xaiv cov pa dawb huv thiab kev ua haujlwm ntawm cov neeg muaj kuab lom nyob hauv lub zog thiab tshuaj lom neeg .
