Abstract
The invention relates to the preparation of novel bi- or tri metallic silicate micro-porous and/or meso-porous materials based on cerium, nickel, copper and/or zinc on a porous silicate framework matrix to use its molecular sieve effect to target preferentially the acidic organic molecules present in hydrocarbon feedstocks like crude oil, bitumen, VGO and the like. The chosen metals are selected based on their ability to activate steam and transfer oxygen for completing the oxidation of carboxylic compounds or decarboxylating them. These composite materials can be prepared under hydrothermal synthesis conditions in order to produce suitable porous solids where the metals are well dispersed and preferentially distributed inside the channels of the silicate framework where they can interact only with the molecules that can go inside the channels. According to the invention, the metallo-silicate materials are prepared under hydrothermal synthesis conditions Modification of the physical-chemical properties of the porous silicate materials can be accomplished by partial replacement of the silicon atoms by cerium, nickel, copper and/or zinc atoms in the material by isomorphous substituti…
