    摘要： A process for oxidation of oxidizable materials which are dissolved or suspended in a liquid phase. A contactor in the form of a porous membrane is used. The contactor is designed such that an oxidizing phase flows along one surface thereof while the phase to be oxidized flows along another surface. The oxidation is catalyzed by (i) a catalyst material which constitutes the porous membrane or is deposited in or onto a porous membrane support, or (ii) a catalyst material which is supplied to one or both of the feed streams comprising the oxidizing phase and the phase to be oxidized.

    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.
