Are there molecular sieves for the trace methane removal in pressure swing adsorption nitrogen production?
Thread Content
For nitrogen production using pressure swing adsorption, it is possible to add a certain type of molecular sieve to the adsorption tower in order to remove methane from the polluted atmosphere (of course, in trace amounts). I wonder if such a substance exists
This is very difficult; nitrogen methane separation is a global challenge
Special adsorption towers must be designed; adding a little molecular sieve can solve the problem of nitrogen-methane adsorption, but at present this is just delusional thinking
Reduce the methane content in the air to below 1 ppm
The separation coefficients of N2/CH4 on silica gel, activated carbon, 5A, mordenite, and 13X adsorbents are 1.86, 2.84, 1.40, 1.39, and 1.52 respectively. The separation coefficients are relatively low, making separation difficult.
Thank you! Only chemical methods can be used
