Abstract: A method of preparing hydrodesulfurization catalysts having cobalt and molybdenum sulfide deposited on a support material containing mesoporous silica. The method utilizes a sulfur-containing silane that dually functions as a silica source and a sulfur precursor. The method involves an one-pot strategy for hydrothermal treatment and a single-step calcination and sulfidation procedure. The application of the hydrodesulfurization catalysts in treating a hydrocarbon feedstock containing sulfur compounds to produce a desulfurized hydrocarbon stream is also specified.

Abstract: In production of a zeolite membrane complex, a starting material solution containing at least a structure-directing agent and FAU-type zeolite particles having an average particle diameter of 50 to 500 nm is prepared. Then, a support is immersed in the starting material solution to form a zeolite membrane on the support by hydrothermal synthesis, the zeolite membrane being composed of AFX-type zeolite. After that, the structure-directing agent in the zeolite membrane is removed.
Abstract: Methods for producing supported catalysts containing a transition metal and a bound zeolite base are disclosed. These methods employ a step of impregnating the bound zeolite base with the transition metal, fluorine, and high loadings of chlorine. The resultant high chlorine content supported catalysts have improved catalyst activity in aromatization reactions.
Abstract: According to the subject matter of the present disclosure, a method of producing an aromatization catalyst may comprise producing a plurality of uncalcined ZSM-5 nanoparticles via a dry-gel method, directly mixing the plurality of uncalcined ZSM-5 nanoparticles with large pore alumina and a binder to form a ZSM-5/alumina mixture, and calcining the ZSM-5/alumina mixture to form the aromatization catalyst. The plurality of uncalcined ZSM-5 nanoparticles may have an average diameter of less than 80 nm.
