Abstract: Disclosed is a catalyst comprising a zeolite comprising a framework, the framework comprising silicon and aluminum, and a noble metal. The zeolite has undergone at least a first exchange with a Group I or II cation or ammonium and thereafter is contacted with a second Group I or II cation. The step of contacting comprises an exchange, incipient wetness, or dry impregnation. The noble metal is deposited at the zeolite.

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: Thermoplastic compositions having reduced odor are described. A thermoplastic composition can include a thermoplastic polymer and a dual active functionalized silica (e.g., an amine-functionalized silica having a specific surface area of less than 450 m2/g and a nitrogen content of at least 1.2 wt. %). Such a thermoplastic composition has decreased odor-active volatile organic compounds (VOCs) emissions when compared with the same thermoplastic composition that does not include the dual active functionalized silica.
