    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.

    摘要： In order to recover hydrogen from a hydrogen-rich gaseous effluent, a procedure is used that comprises: in a stage (a), bringing a hydrocarbon-rich gaseous effluent into contact with the upstream face of a hydrogen-selective membrane at a pressure P1; in a stage (b), bringing a flow containing one or more unsaturated compound(s) into contact with the downstream face of a membrane at a pressure P2, which is smaller than P1, in the presence of a catalyst, to hydrogenate at least a portion of the unsaturated compound(s) using at least a portion of the hydrogen that passes by permeation through the upstream face to the downstream face of the selective membrane; and in a stage (c), transporting a flow containing the hydrogenated compound(s) into stage (b).

    摘要： A process is described for preparing a supported zeolite membrane constituted by a composite continuous zeolite/support layer of controlled thickness, wherein the zeolitic phase is principally localized in the pores of a porous support and optionally on the external surface thereof, the process comprising at least the formation of a precursor gel of the zeolite, bringing the gel into contact with the support and crystallizing the zeolite. The zeolite is crystallized by carrying out a thermal program comprising at least three steps in succession: a first constant temperature stage carried out at a temperature in the range 50° C. to 300° C., cooling to a temperature of strictly less than 50° C. followed by a second constant temperature stage carried out at a temperature range of 50° C. to 300° C. The prepared membrane is used in particular in processes for separating gas or separating liquids.
