A minor issue with the catalyst in carbon monoxide conversion
Thread Content
I would like to ask the experts: in a carbon monoxide shift reactor, at a pressure of 80 kilograms and a temperature of 380°C, can the catalyst withstand such pressure? Could there be issues such as catalyst pulverization or fragmentation? What catalyst is suitable, and what is its approximate price?
I’m not sure about this; a Co-Mo catalyst is used, the pressure is generally below 30 kilograms, and by changing the furnace temperature, it’s possible to reach 380 degrees℃
To correct something mentioned above: for Co-Mo sulfur-resistant shift catalysts, a pressure of over 30 KG is generally required; catalysts that are cheaper can be used when the pressure is below 30 KG. The pressure reaches 80 kg; this is pressurized gasification of water-coal slurry. Zhejiang XinHengRui’s K8-11G can ensure operation under these conditions without any powdering occurring. The other catalysts are unclear.
No, it involves a methanation process using methanol exhaust gas; the feed gas entering the system amounts to 80 kilograms, and the resulting product is CNG. If pressure is reduced and then a compressor is used, the energy consumption will be too high, making the operation cost-prohibitive! So it’s best to choose a catalyst that is not affected by this pressure!
The catalyst can withstand this pressure at a pressure of 80 kilograms and a temperature of 380°C! There will be no catalyst pulverization, crushing, or anything like that! Iron-chromium catalysts are generally used, with a price of around 20,000 to 30,000 yuan per ton!
K8-11 and QCS-01 are fine

Convert CO to CO2 and then carry out decarbonization? There is no issue with the operating temperature at B113; it’s not clear whether the pressure can be withstood, so it would be advisable to contact Liaohe Catalyst Factory for information
For the QDB-03 catalyst, the poster can contact me via email at lysteven1984@163.com. I’m happy to help with whatever you need! Hehe
