US Patent 10000715 Catalytic depolymerisation of polymeric materials

A process for converting a molten polymeric material is provided. The process includes effecting disposition of a molten polymeric material, having at least one carbon-carbon double bond, in sufficient proximity to a catalyst material within a reaction zone, to effect a reactive process that effects generation of a reaction product. The reactive process effects cleaving of at least one carbon-carbon double bond. The catalyst material includes [Fe—Cu—Mo—P]/Al2O3 prepared by binding a ferrous-copper complex to an alumina support to generate an intermediate material, and reacting the intermediate material with a heteropolyacid.
