Carbon monoxide CO ukususwa catalyst nge Noble metal

Carbon monoxide CO ukususwa catalyst nge Noble metal

Carbon monoxide CO ukususwa catalyst kunye Noble metal Umfanekiso Featured
  • Carbon monoxide CO ukususwa catalyst nge Noble metal

inkcazelo emfutshane:

Ikhabhon monoxide CO yokususa icatalyst eveliswe yiXintan yintsimbi ephucukileyo (palladium) esekwe kwi-alumina carrier catalyst, esetyenziselwa ukususa i-H2 kunye ne-CO kwi-CO2 nge-160℃ ~ 300℃。Inokuguqula i-CO ibe yi-CO2 kwaye iguqule i-H2 ibe yi-H2O.Ayibandakanyi i-MnO2, i-CuO okanye isulfure, ngoko ingasetyenziselwa ukuhlanjululwa kwe-CO2 kwi-CO2, esetyenziswa ngokubanzi kwishishini lokutya.
Ngezantsi iimeko eziphambili zale ntsimbi yentsimbi exabisekileyo.
1）Umxholo wesulfure uwonke≤0.1PPM.(isitshixo iparameter)
2) Uxinzelelo lokusabela <10.0Mpa, iqondo lobushushu lokuqala le-adiabatic reactor lihlala li-160 ~ 300℃.


Iinkcukacha zeMveliso

Iithegi zeMveliso

imveliso parameters

Izithako I-AlO kunye ne-palladium (Pd)
Ubume ingqukuva
Ubungakanani Ububanzi: 3mm-5mm

Uxinzelelo lokusebenza ＜10.0Mpa
Ukulayisha umlinganiselo wobude kunye nobubanzi 3:1

Ifomula yokubala ubungakanani obufunekayo

A) Ngokusekwe kwi-CO kunye ne-H2 yoxinzelelo, ukuhamba komoya kunye nobushushu bokusebenza kunye nokufuma.
B) Umthamo we-catalyst=I-Airflow/GHSV.
C) Ubunzima be-catalyst=Volume*Ubunzima obuthile obukhethekileyo(ubuninzi bobuninzi)
D) Xintan unokunika iingcebiso zobungcali malunga nobungakanani obufunekayo

Ilayisha amacebiso

Ukuhla koxinzelelo lwebhedi ye-catalyst kwiplanti yoshishino inxulumene ngokusondeleyo nomlinganiselo wobude ukuya kububanzi bebhedi ye-catalyst, ubungakanani bokuhamba kwegesi, i-porosity yepleyiti yokuhambisa igesi, imilo kunye nobukhulu bamasuntswana e-catalyst, amandla oomatshini kunye nokusebenza. iimeko zenkqubo.Ngokwamava ethu, umlinganiselo wobude ukuya kwidayamitha yebhedi ye-catalyst ilawulwa malunga ne-3: 1.

Nika ingqalelo kwimpembelelo ye-bubble kunye nenkungu ye-asidi xa usebenzisa kwaye ugcina i-catalyst.Xa ugcwalisa, beka kuqala umaleko we-mesh yensimbi engenasici (i-aperture yi-2.5 ~ 3mm), kwaye ubeke umaleko omalunga ne-10cm ibhola ye-ceramic engqingqwa (Ø10 ~ 15mm);Uluhlu lwe-mesh ye-stainless wire mesh lubekwe kwindawo ephezulu ye-ceramic layer njengenkxaso ye-catalyst bed, kwaye ke i-catalyst ilayishiwe.Xa ulayisha, abasebenzi abachaphazelekayo kufuneka banxibe iimaski zothuli, kwaye ukuphakama kwe-catalyst free fall akufanele kube ngaphezu kweemitha ezi-0.5.Beka umaleko wentsimbi engenastainless wire mesh phezu kwebhedi epakishelwe yi-catalyst, uze ubeke ibhola yeceramic (Ø10 ~ 15mm) enobunzima obuyi-10 ~ 15cm.

I-catalyst ayifuni unyango lokunciphisa ngaphambi kokusetyenziswa.

Ukuthumela ngenqanawa, ukuPakisha kunye nokugcinwa

A) I-Xintan inokuhambisa imithwalo engaphantsi kwe-5000kgs kwiintsuku ezisi-7.
B) 1kg kwiphakheji yokufunxa.
C) Yigcine yomile kwaye utywine igubu lentsimbi xa uligcina.

Ukusetyenziswa kwe-CO catalyst yokususa

Ngokukhethekileyo isetyenziselwa i-CO kunye ne-H2 ukususa kwi-CO2, inokuguqula i-CO ibe yi-CO2 nge-oxidation kwaye iguqule i-H2 kwi-H2O Isicelo sikhuselekile kwaye singenamandla.
