GAS SEPARATING BODY AND METHOD FOR PRODUCING SAME |
摘要 |
The present invention discloses a gas separator comprising a porous substrate composed of a first ceramic and a gas-separating layer containing zeolite, disposed on the surface of the porous substrate, wherein the gas-separating layer contains, in addition to zeolite, a thermal expansion coefficient-adjusting material composed of a second ceramic having a linear thermal expansion coefficient satisfying a predetermined relation so that the difference in thermal expansion coefficient between the porous substrate and the gas-separating layer can be reduced. The gas separator of the present invention can be used preferably particularly in selective separation of carbon dioxide (CO2) or the like from a mixed gas such as natural gas or the like. |
