Latest Patents

Valentin Valtchev's latest patents include a catalyst in the form of grains comprising an acidic porous core surrounded by a uniform outer layer. This invention relates to a catalyst that comes in the form of grains, each grain consisting of a core covered by at least one external layer. The core consists of an acidic porous solid and has a size of between 0.1 micron and 0.4 millimeter. The external layer has a uniform thickness with a uniformity criterion C, which is less than 0.30. This criterion is defined as the average, on a number N of catalyst grain samples, of the ratio of the difference between the maximum thickness, Ei, of the external layer and the minimum thickness, Ei, of this same layer to the average of these two thicknesses Ei and Ei.

Another significant patent is related to FAU-structural-type supported zeolite membranes, their process for preparation, and their applications. This invention involves a FAU-type zeolite membrane that comprises a FAU-type zeolite crystal layer incorporated in the surface porosity of at least one selected face of a porous substrate. The ratio between the thickness of the zeolite layer incorporated in the surface porosity of the selected face of the substrate and the total thickness of the zeolite layer is at least 70%. It also relates to processes for preparation and application of these membranes.
