    Abstract: Disclosed are hybrid Fischer-Tropsch catalysts containing cobalt and ZSM-48 zeolite. The hybrid Fischer-Tropsch catalysts can contain cobalt deposited on ZSM-48 extrudate supports. Alternatively, the Fischer-Tropsch catalysts can contain cobalt deposited on supports mixed with ZSM-48 particles. It has surprisingly been found that the use of hybrid Fischer-Tropsch catalysts containing ZSM-48 zeolite in synthesis gas conversion reactions results in improved C5+ productivity and catalyst activity, as well as a desirable product distribution including low formation of methane and C21+.

    Abstract: An amorphous support, methods for making the same and methods of using, particularly in hydrocracking. A method of making may comprise mixing a first amorphous material and a second amorphous material of different acidities to form a mixture, and treating by either separately treating the first and second amorphous materials before mixing or treating the mixture, so as to form an amorphous catalyst support. Treating preferably includes calcining. The acidity of the amorphous support may be modified by the different acidities of the precursor amorphous materials, their proportions in the mixture, and/or the order of the mixing and treating steps. A method of use may comprise reacting a hydrocarbon fraction with hydrogen over a hydrocracking catalyst comprising the amorphous catalyst support to form a hydrocracked product. Further embodiments include the first and second amorphous materials comprising silica-alumina, and/or differing in Brönsted acidity, Lewis acidity, or acidity index.

    Abstract: A method is provided for forming a highly active Fischer-Tropsch catalyst using boehmite having a particular crystallite size. In this method, a support material comprising boehmite is contacted with a catalytic metal-containing compound to form a catalyst precursor. The boehmite is selected to have an average crystallite size in the range of from about 6 nanometers (nm) to about 30 nm. An alternate embodiment uses a mixture of boehmites with various average crystallite sizes in the range of from about 4 nm to about 30 nm, differing by at least by 1 nm. Subsequently, the catalyst precursor is calcined to convert the boehmite to a stabilized aluminum oxide structure, thereby forming a catalyst support having a good attrition resistance and a relatively high hydrothermal stability.
