Abstract: Catalysts for dewaxing of hydrocarbon feeds, particularly feeds with elevated sulfur and nitrogen levels, are provided. The dewaxing catalysts include a zeolite with a low silica to alumina ratio combined with a low surface binder, or alternatively the formulated catalyst has a high ratio of zeolite surface area to external surface area.

Abstract: A process for the preparation of a catalyst useful for conducting carbon monoxide hydrogenation reactions, particularly Fischer-Tropsch reactions; the catalyst compositions, use of the catalyst compositions for conducting such reactions, and the products of these reactions. The steps of the process for producing the catalyst comprise mixing together in solution (a) a compound, or salt of a Group VIII metal, e.g., Co(NO3)2; (b) a compound, or salt of magnesium, e.g., Mg(NO3)2; (c) a compound, salt, or powdered oxide of a Group IVB metal, e.g., zirconia; (d) a refractory inorganic oxide, e.g., kieselguhr; and (e) an ammonium or alkali metal salt precipitating agent, e.g., Na2CO3, to produce a precipitated solids mass, or catalyst precursor, and then reducing the precipitated solids mass, or catalyst precursor, to form a catalyst, e.g., (100 Co:6 MgO:10 ZrO2:200 kieselguhr). The precipitated solids mass, or catalyst precursor, is shaped and brought to a critical level of moisture, and reduced.
