    摘要: This invention relates to a process for the preparation of a supported zeolite membrane that consists of a zeolite/substrate composite layer, whereby the crystallization stage is carried out while being stirred by a hydrothermal treatment of the immersed substrate. In addition, the process satisfies at least one of the following requirements: The crystallization is carried out with a water/silica molar ratio of 66-100, Before the crystallization stage, the porous substrate is pretreated by covering it at the outer periphery, where the zeolite is not desired, with a polytetrafluoroethylene film and by impregnating it with water in the pores where the zeolite is not desired, and the crystallization is conducted with a water/silica molar ratio of 10-100.
