Reaction Mechanism thiab txheej txheem kev koom ua ke
Carbonyl sulfide tiv thaiv kev tshem tawm ncaj qha los ntawm cov txheej txheem lub cev hnyav lossis kev ntxuav yooj yim hauv ntau cov dej ntws. Cov catalyst no pab txhawb cov tshuaj tiv thaiv heterogeneous catalytic ntawm nws cov active alumina nto:
COS + H2O ->H2S + CO2
Cov tshuaj tiv thaiv no hloov cov organic sulfur rau hauv hydrogen sulfide, uas yooj yim dua los txhuam siv cov pa hlau oxide polishers.
Hom Ob -Theem Purification Tsheb ciav hlau
Raw Gas (with COS) -> Hydrolysis Reactor -> H2S Intermediate ->Downstream ZnO Polishing Unit
Qhov kev teeb tsa no tiv thaiv cov fouling ntxov ntxov ntawm sulfur- cov kab mob qis qis (xws li hydrogenation lossis methanation catalysts) thaum zam kev siv hluav taws xob siab cuam tshuam nrog thermal high -kub hydrolysis systems.
Kev khiav hauj lwm qhov rais thiab txheej txheem Parameter
Kev khiav hauj lwm kev ua tau zoo nyob ntawm kev tswj kom muaj qhov sib npaug ntawm cov pa tshaj tawm, noo noo, thiab kub.
Tsawg-Tsub Muaj Peev Xwm:Ua haujlwm tau zoo ntawm 0C thiab 150C, txo cov nqi hluav taws xob los ntawm kev tshem tawm cov khoom noj sab nraud- roj preheating hauv ambient- huab cua kub lossis qis -enthalpy ntws.

FAQ
Q: Qhov no catalyst ua li cas hauv cov dej ntws uas muaj cov pa roj carbon dioxide lossis hydrogen sulfide?
A: Lub alumina -raws li matrix yog tshuaj ruaj khov nyob rau hauv siab - cov kwj siab uas muaj qib siab CO2 thiab nruab nrab H2S. Txawm li cas los xij, kev ntsuam xyuas ua ntej ntawm cov roj dew cov ntsiab lus thiab cov kua qaub roj sib piv yuav tsum tau tiv thaiv kom tsis txhob muaj cov kua dej condensation los yog cov pore hauv cheeb tsam hauv lub txaj ruaj khov.
Q: Puas yog thermal regeneration tuaj yeem ua tau thaum lub catalyst pom cov cim ntawm kev ua haujlwm poob?
A: Yog. Yog hais tias deactivation feem ntau yog tshwm sim los ntawm reversible thib ob sulfur deposition los yog lub teeb hydrocarbon tsub kom, lub txaj yuav tsum regenerated nyob rau hauv -situ siv ib tug tswj inert gas los yog rhuab qab zib kua pururge uas muaj stoichiometric dej vapor ntawm qhov kub thiab txias, raws li cov kev qhia tshwj xeeb engineering.
Q: Dab tsi yog cov txheej txheem thauj khoom pom zoo rau kev lag luam - nplai ruaj - txaj reactors?
A: Lub catalyst yuav tsum ntom -loaded los yog thom khwm- loaded siv tshwj xeeb loading chutes kom txo tau pellet breakage thiab plua plav. Ib qho kev txhawb nqa ntawm cov khoom siv hluav taws xob tsis zoo (feem ntau qhov ntau thiab tsawg ntawm 10mm mus rau 25mm) yuav tsum muab tso rau hauv qab thiab sab saum toj ntawm lub reactor kom faib cov roj ntws sib npaug thiab tiv thaiv kev tsiv teb tsaws chaw.
Q: Yuav ua li cas hloov cov dej noo nyob rau hauv cov pa roj muaj feem xyuam rau lub sij hawm ntev - conversion efficiency?
A: Cov tshuaj tiv thaiv hydrolysis cia siab rau cov dej vapor txaus nyob hauv cov dej ntws. Kev hloov pauv hauv qab ntawm qhov pib stoichiometric yuav txo qis COS hloov pauv sai. Yog tias pub roj av noo tsis tu ncua, kev txhaj tshuaj txuas ntxiv los yog cov av noo noo yuav tsum tau muab tso rau hauv qab ntawm lub catalytic reactor.
