Abstract: Methods for the hydrogenation of aromatic-containing polymers are described. A method includes hydrogenation of polymers by contacting a polymer solution that includes an aromatic-containing polymer and a mixture of a non-polar solvent and a polar solvent having a dielectric constant greater than 7.6 at 25° C. and a non-polar solvent having a dielectric constant of 5 or less at 25° C. with a hydrogenation catalyst to produce polymer composition that includes at least one hydrogenated and/or at least one partially hydrogenated aromatic ring. The polar to non-polar solvent volume ratio ranges from 10:90 to 80:20.

Abstract: A chemical reactor system includes: a feed; a methane oxychlorination catalyst, wherein a product of an oxychlorination reaction is dichloromethane; and a dichloromethane conversion catalyst, wherein the dichloromethane conversion catalyst provides a product stream having a dichloromethane selectivity less than 5%. The addition of the dichloromethane conversion catalyst to the reactor bed can decrease the amount of dichloromethane produced and increase the amount of monochloromethane produced. Accordingly, dichloromethane does not have to be separated from the product stream and the monochloromethane can then be used to produce other products, such as olefins.

Abstract: A polymer, methods of making the polymer, methods of recycling the polymer and compositions including the polymer are described. The polymer can contain repeating units of Formula (I), where n is 1 and denotes number of repeat units, X is an aliphatic group, and Z is an aliphatic hydro-carbon group having at least 45 carbon atoms, preferably 45 to 1,000 carbon atoms, and has a degree of saturation 98 to 100%. The polymer contains 0.01 to 40 ester groups per 1000 backbone carbon units and has a melt temperature (Tm) of 40° C. to 180° C. as measured by DSC at a heating rate of 10° C. per min.

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.
