MFI zeolite membrane for separating nitrogen and sulfur hexafluoride and preparation method of the same |
| abstract |
The present invention relates to an MFI zeolite layer; And the nitrogen permeability coating in the MFI zeolite layer surface 50 barrer or more polymers; provides a nitrogen (N 2) and sulfur hexafluoride (SF 6) separating the zeolite separation membrane for containing the membrane during heat treatment of conventional MFI membrane SF 6 can be effectively separated from the waste gas containing N 2 and SF 6 by compensating for the thermal defects that are generated, and it has an effect of preventing moisture adsorption due to surface hydrophobicity. |
