I-Carbon monoxide CO ukususa i-catalyst nge-Noble metal

I-Carbon monoxide CO ukususa i-catalyst nge-Noble metal

I-Carbon monoxide CO esusa i-catalyst ene-Noble metal Isithombe Esifakiwe
  • I-Carbon monoxide CO ukususa i-catalyst nge-Noble metal

incazelo emfushane:

I-Carbon monoxide CO ukususa i-catalyst ekhiqizwe i-Xintan iyi-catalyst yensimbi ehloniphekile (i-palladium) esekelwe ku-alumina carrier catalyst, esetshenziselwa ukususa i-H2 ne-CO ku-CO2 ku-160 ℃ ~ 300 ℃.Ingakwazi ukuguqula i-CO ibe yi-CO2 futhi iguqule i-H2 ibe yi-H2O.Ayifaki i-MnO2, CuO noma isulfure, ngakho-ke ingasetshenziswa ngokuphepha ekuhlanzeni i-CO2, esetshenziswa kabanzi embonini yokudla.
Ngezansi izimo ezibalulekile zalesi sithako sensimbi esiyigugu.
1）Isamba sokuqukethwe kwesibabule≤0.1PPM.(ipharamitha yokhiye)
2) Ingcindezi yokusabela engu-<10.0Mpa, izinga lokushisa lokuqala le-adiabatic reactor livamise ukuba ngu-160 ~ 300℃.


Imininingwane Yomkhiqizo

Omaka bomkhiqizo

imingcele yomkhiqizo

Izithako I-AlO ne-palladium (Pd)
Isimo i-sphere
Usayizi Ububanzi: 3mm-5mm
Ukuminyana ngobuningi 0 .70~0.80g/ml
Indawo engaphezulu ~ 170m2/g
I-GHSV 2.0–5.0×103
Ukusabela kokuqukethwe kwe-CO ku-tail gas 1 ppm
Izinga lokushisa lokusebenza 160-300 ℃
Impilo yokusebenza Iminyaka engu-2-3
Ingcindezi yokusebenza ＜10.0Mpa
Ilayisha isilinganiso sobude nobubanzi 3:1

Ifomula yokubala inani elidingekayo

A) Ngokusekelwe ekugxilweni kwe-CO ne-H2, ukugeleza komoya kanye nezinga lokushisa elisebenzayo kanye nomswakama.
B) Umthamo we-catalyst=Airflow/GHSV.
C) Isisindo se-catalyst=Volume*I-Gravity ethize ngobuningi(inqwaba yokuminyana)
D) I-Xintan inganikeza iseluleko sochwepheshe ngenani elidingekayo

Ilayisha amathiphu

Ukwehla kwengcindezi yombhede we-catalyst embonini yezimboni kuhlobene eduze nesilinganiso sobude nobubanzi bombhede we-catalyst, usayizi wokugeleza kwegesi, i-porosity yepuleti lokusabalalisa igesi, ukwakheka nosayizi wezinhlayiya ze-catalyst, amandla emishini kanye nokusebenza. izimo zenqubo.Ngokolwazi lwethu, isilinganiso sobude nobubanzi bombhede we-catalyst silawulwa cishe ku-3:1.

Naka kakhulu umphumela webhamuza nenkungu ye-asidi lapho usebenzisa futhi ugcina i-catalyst.Uma ugcwalisa, qala ubeke ungqimba lwensimbi engenasici (imbobo ingu-2.5 ~ 3mm), bese ubeka ungqimba lwebhola le-ceramic eliwugqinsi elingu-10cm (Ø10 ~ 15mm);Isendlalelo socingo lwensimbi engagqwali lubekwe engxenyeni engenhla yesendlalelo se-ceramic njengokusekela kombhede we-catalyst, bese i-catalyst ilayishwa.Lapho ulayisha, izisebenzi ezithintekayo kufanele zigqoke imaski yothuli, futhi ukuphakama kokuwa kwamahhala kwe-catalyst akufanele kube ngaphezu kwamamitha angu-0.5.Beka ungqimba lwensimbi engenasici phezu kombhede we-catalyst opakishiwe, bese ubeka ibhola le-ceramic (Ø10 ~ 15mm) elinogqinsi luka-10 ~ 15cm.

I-catalyst ayidingi ukwelashwa kokunciphisa ngaphambi kokusetshenziswa.

Ukuthumela, Iphakheji kanye nesitoreji

A) I-Xintan ingaletha impahla engaphansi kuka-5000kgs phakathi nezinsuku ezingu-7.
B) 1kg ephaketheni levacuum.
C) Yigcine yomile bese uvala isigubhu sensimbi uma usigcina.

Izicelo ze-CO catalyst yokususwa

Isetshenziselwa ngokukhethekile ukususwa kwe-CO ne-H2 ku-CO2, Ingakwazi ukuguqula i-CO ibe yi-CO2 ngokusebenzisa i-oxidation futhi iguqule i-H2 ibe yi-H2O Isicelo siphephile futhi asinawo amandla.
