Sulfur Recovery Al2O3 Activated Alumina Catalyst

A918 catalyst ntawm sulfur rov qab yog ib qho khoom siv hluavtaws ua haujlwm Al₂O₃catalyst, uas muaj kev ua tau zoo ntawm cov tshuaj tiv thaiv sulfated,

ntau dua hydrolysis muaj nuj nqi ntawm cov organic sulfur tebchaw thiab zoo dua tus cwj pwm ntawm tshav kub tsis tu ncua.

Cov txiaj ntsig ntawm kev sim ua haujlwm tau ua pov thawj tias A918 catalyst muaj qhov zoo ntawm kev ua haujlwm siab thiab tuav lub zog, uas tuaj yeem siv tau 3 xyoos tsis tu ncua.

Piv nrog rau bauxite, tag nrho cov txiaj ntsig ntawm leej faj rov qab tuaj yeem nce los ntawm 80 ~ 85% mus rau 94 ~ 96% hauv cov txheej txheem sib npaug lossis zoo sib xws. Lub hydrolysis ntawm COS tau mus txog 100% thiab cov sulfur tus nqi ntawm tus Tsov tus tw roj tau txo qis hauv qab mus rau 1%.

Txhua yam khoom ntawm A918 catalyst, uas nws qhov chaw tshwj xeeb tau ncav cuag 320m²/g, tau mus txog qib siab hauv ntiaj teb.

Cov txheej txheem Claus yog siv los ntawm Sulfur Recovery Industry uas hloov hydrogen sulfide rau hauv cov ntsiab lus sulfur thiab dej. Cov roj av "qaub" muaj ntau cov hydrogen sulfide nyob rau hauv thiab yog tias cov roj no raug hlawv ua roj, Sulfide khiav tawm, ua rau huab cua muaj kuab lom thiab puas tsuaj rau peb ib puag ncig kev sib tw. Nws tau dhau los ua ib qho kev xav tau ntawm tib neeg los hloov siab tshaj plaws ntawm leej faj los ntawm "kua" roj.

Al2O3 Activated Alumina yog qhov siv dav tshaj plaws Claus Catalyst uas muaj ntau tus catalytically. active nto qhov chaw uas absorbs Hydrogen Sulfide (H2S) thiab Sulfur Dioxide (SO2) rau tom qab cov tshuaj tiv thaiv rau yield elemental sulfur.

Nyob rau hauv ntau cov kua qaub roj, leej faj muaj nyob rau hauv ntau lub tebchaw xws li H2S, COS, CS2, thiab lwm yam. Qee qhov ntawm lawv yuav tsis muaj nyob rau hauv cov pa roj, tab sis cubustion ntawm H2S nyob rau hauv muaj CO2 los yog hydrocarbons yuav ua rau tsim COS. /CS2. Cov tebchaw no yuav tsum tau hloov dua siab tshiab kom ntseeg tau tias kev hloov pauv ntawm leej faj. Txij li cov decomposition tus nqi ntawm cov tebchaw yog qis dua li ntawm H2S / SO2 cov tshuaj tiv thaiv, yuav tsum muaj cov catalyst muaj zog heev. Sulfation tuaj yeem yog lwm qhov teeb meem vim nws txo qhov chaw saum npoo thiab yog li, qhov deactivation ntawm catalyst.

Peb cov kev ua tau zoo Sulfur Recovery Al2O3 Activated Alumina Catalyst yog qhov zoo tagnrho rau Claus units hauv cov nroj tsuag roj, roj refineries, coke nroj tsuag, tail gas units, thiab lwm yam.
