Seek a methanation unit
Thread Content
I am currently working on a project related to methanation, but there is very little information available on this topic, especially regarding the equipment used. Additionally, due to my limited access rights, I cannot access many of the relevant materials. If any of you experts have information on this topic, such as schematic diagrams or process flows, I would be extremely grateful if you could send them to me. liyongchaoid@163.com
For the laboratory, a simple fixed-bed setup will suffice; characterizing the catalyst is rather complicated, so it’s best to look up more information on the subject
Reply to 2# qinzhifeng: I’m familiar with that laboratory. I’d like to learn more about the equipment diagrams and control conditions in the production process. There are also import and export conditions.
What are the operating conditions you plan for methanation? Should it be for purification or for natural gas? I’d like to give you some advice; we have been working on methanation catalysts for over 20 years. It is currently the number one brand in China for ammonia synthesis plants.
Reply to 4# Catalyst Expert: I want to take a look at the process of existing methanation units; those based on coal gas production would be ideal. It’s not convenient to disclose anything regarding the catalysts.
Should it be used for coal-to-ammonia production or for natural gas production? Please be more detailed
Reply to 6# Catalyst Expert: I work in the field of catalysts. If you have information related to both ammonia synthesis and coal gas production, it would be great if you could share it. There is a lack of relevant data, and I hope to learn more about this topic. Thank you very much.
The production of synthetic ammonia is relatively straightforward, and almost all coking plants have the capability to do it. Since urea synthesis requires a decarburization step, namely methanation, the industrial production of synthetic natural gas has not yet been scaled up; only pilot-scale facilities in large chemical plants have achieved success, with such projects being carried out in Weifang, Shandong
Let’s study isothermal tubular reactors; this can reduce the requirements for catalysts, and I personally think it’s better than adiabatic reactors
At present, all industrialized methanation reactors at home and abroad are adiabatic fixed-bed reactors; at least to date, no isothermal or variable-temperature tubular reactors have been seen.
