    摘要： Described is a process for the preparation of a supported zeolite membrane that consists of a zeolite/substrate composite layer, whose zeolite phase exhibits a crystallinity of at least 85%, comprising: a) the formation of a gel or a solution that comprises at least one source of silica and water, supplemented with at least one polar organic compound, b) bringing into contact said gel or said solution with a porous substrate, c) the crystallization of the zeolite starting from said gel or said solution; and d) the elimination of residual agents. The molar ratio of the water to the silica in the gel or the solution in stage a) is between 27:1 and 35:1. The crystallization time of stage c) is at least 25 hours.Said process is particularly suited for the preparation of zeolite membranes whose zeolite phase is of the MFI-structural type.
