Abstract: Catalysts for the hydrogenation of aromatic containing polymers are described. Such a catalyst can include, based on the total weight of the catalyst, 99.1 wt. % to 99.95 wt. % of a metal oxide support, and 0.05 wt. % to 0.9 wt. % of catalytic metal nanoparticles comprising platinum (Pt), palladium (Pd), ruthenium (Ru), any combination thereof, or alloy thereof. The catalyst can have a specific surface area of 5 m2/g to 80 m2/g, a pore volume of 0.01 cm3/g to 0.35 cm3/g, and a catalyst median particle size of less than 300 microns. Processes to produce the catalyst and methods of hydrogenating aromatic containing polymers are also described.

Abstract: The invention relates to a composition containing a catalyst having high catalytic stability for conducting oxidative coupling of methane (OCM) at high carbon efficiency, while improving both methane and oxygen conversion. Particularly, the inventive catalyst is a metal oxide supported catalyst, which contains an alkali metal promoter and a mixed metal oxide component having at least one alkali earth metal and at least one rare earth metal. The metal oxide support is selected in a manner, such that at least a portion of the metal oxide support is capable of reacting with at least a part or whole of the alkali metal promoter under conditions of calcination during catalyst preparation. The invention further provides a method for preparing such a metal oxide supported catalyst composition, using a calcination process. Additionally, the invention further describes a process for producing C2+ hydrocarbons, using such a catalyst composition.
