A method is disclosed for synthesizing zincoaluminosilicate molecular sieve SSZ-41 having high aluminum content from a combined source of silicon oxide and aluminum oxide selected from one or more a FAU framework type zeolite and a colloidal aluminosilicate.

The present disclosure is directed to methods of producing zincoaluminosilicate structures with AEI, CHA, and GME topologies using organic structure directing agents (OSDAs), and the compositions and structures resulting from these methods.

The present disclosure is directed to producing zeolite structures with GME topologies using organic structure directing agents (OSDAs) comprising a piperidinium cation, and the compositions and structures resulting from these methods. In some embodiments, the crystalline products have a molar ratio of a molar ratio of Si:Al that is greater than 3.5.

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 substitutions of these elements in a synthesis gel or by post-synthesis modifications like ion-exchange or impregnation/deposition. The materials can be used as prepared catalysts for the steam catalytic reduction of the total acid number (TAN) in acidic crude oil feedstocks and in the presence of steam and/or CO.sub.2 as oxidizing agent to complete decarboxylation and to keep the metal oxide active sites from reducing and deactivating as well as other partial upgrading reactions.
