Abstract
Gas permeation through zeolite membranes can be extremely sensitive to organics or moisture, adsorbed from feed impurities or from the atmos phere during storage, and thus, thermal pretreatment is necessary to o btain reliable permeation rates. Altered adsorption properties of the external surface and selective pore blockage might have caused the obs erved trends.
