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.
