Seeking cooperation on deoxygenation technology for oxygenated coalbed methane
Thread Content
We are seeking cooperation in the field of coalbed methane deoxygenation. A coal mine in Jincheng, Shanxi has approached us for solutions to handle coalbed methane. The details regarding the gas supply are as follows: 1. Coalbed methane processing capacity: 360 million Nm3/year (equivalent to 120 million Nm3/year of pure methane); 2. Composition of gas from the mine: 33% CH4； O2 12% ； N2 51% ； H2O 3%, temperature at 35°C, pressure at atmospheric pressure. We hope that capable companies will get in touch with us to collaborate on development—whether it’s pressure swing adsorption, catalytic combustion, or other technical solutions.
Oxygen removal from coalbed methane is quite difficult, and this composition falls within the explosive range
The range for gas explosions seems to be a methane content of 5-15%, right?

This project requires substantial investment. I have experience in the separation and enrichment of coalbed methane; at present, cryogenic methods seem to be the most viable option, though they are energy-intensive. An appropriate adsorbent has not yet been found for adsorption methods. If you need any further information, feel free to contact me via QQ or email
Reply to 6# xxqm: Cryogenic treatment is one possible solution; it seems that the Institute of Physics and Chemistry is using this method at present. However, cryogenic treatment isn’t just related to energy consumption – there is also a risk of explosion. What’s your QQ number? We can discuss this further
I think it can be enriched using a 2-stage membrane method! Using a nitrogen film and an oxygen-enriched film. It’s just a new field that needs to be tested!
I sent you a QQ message and also left you a text message. I hope you’ll get in touch with me!

Is it easy to produce pressure swing adsorption carbon molecular sieves?
I work in the field of coalbed methane LNG; we can communicate if needed: handshake
