  • Method of preparing heterogeneous zeolite membranes
    Patent number: 11596905
    Abstract: Disclosed are a heterogeneous zeolite membrane and a method of preparing the same, and more particularly a heterogeneous zeolite membrane that has CHA and DDR zeolite structures by growing seed particles into a crystal structure different from that of the zeolite membrane and can thus separate CO2/N2 and CO2/CH4 even under wet conditions, a method of preparing the same, and a method of capturing and removing carbon dioxide using the membrane.
    Type: Grant
