Abstract: Catalysts for replacing rhenium-containing multimetallic catalysts for the hydrogenolysis of organic compounds to desired polyols, including the conversion of glycerol to propylene glycol, are described. The catalysts are carried on carbon supports, as well as carbon supports impregnated with Zirconium Scandium (ZrSc), Zirconium Yttrium (ZrY), Titanium Scandium (TiSc), or Titanium Yttrium (TiY) to texture the carbon support and to create oxygen-ion vacancies that can be used during the desired reactions. Processes for the hydrogenolysis of organic compounds to desired polyols using the disclosed catalysts, including the conversion of glycerol to propylene glycol, are also described.

Abstract: Disclosed herein are zeolite compositions comprising structural units of the formulae: wherein “B” and “C” are spacer groups comprising C2 to C20 hydrocarbyl groups; and R1 and R2 independently of each other comprise alkali metal, hydrogen, or C1 to C20 alkyl groups. The zeolite compositions further comprise structural units derived from a heteropolyacid compound of the formula: (M3)3(M4)(M5)12O40; where M3 comprises hydrogen or an alkali metal; M4 comprises phosphorus or silicon, and M5 comprises tungsten or molybdenum. Methods for preparing these zeolite compositions are also disclosed. The zeolite compositions are useful as catalysts for producing bisphenols.
