Disclosed are shaped dehydrogenation catalysts, methods for making the catalysts, and methods for dehydrogenating a hydrocarbon using the catalyst. A method for making the shaped dehydrogenation catalyst can include combining a group 13 metal precursor and a group 1 metal precursor with a catalyst support precursor to form a shapeable material, shaping the shapeable material to form a wet shaped material, drying the wet shaped material to form a dry shaped material, and calcining the dry shaped material to form the shaped dehydrogenation catalyst.

The invention relates to a mixed oxide composed of zirconium, cerium, lanthanum and at least one rare earth oxide other than cerium and lanthanum, having a specific porosity and a high specific surface area; to the method for preparing same and to the use thereof in catalysis.

Described herein are novel and inventive dewaxing processes that employ dewaxing catalysts which are co-extrusions of two different zeolites, particularly two different 10MR zeolites or a co-extrusion of a 10MR zeolite and a 12MR zeolite in combination with a hydrogenation component. The hydrogenation component can be a mixture of non-noble metal components or a mixture of noble metal components. This novel and inventive process demonstrated a significant activity boost (as measured by increased cloud point reduction) and/or selectivity boost (as measured by reduced diesel loss) compared to either single zeolite component.
