Abstract: 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 affect 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.

Abstract: An apparatus for mixing two or more substances, the apparatus comprising: (a) a first surface, the first surface having a first profile, (b) a second surface spaced apart from the first surface, the second surface having a second profile, (c) a mixing gap formed between the first and second profiles of the first surface and the second surface, and (d) at least one input channel in liquid communication with the mixing gap, to feed the mixing gap with the two or more substances to be mixed.

Abstract: In a process for converting mixed polyethylene waste to make waxes and grease base stocks through catalytic depolymerization, the mixed polyethylene waste is preheated to form a molten mixed polyethylene waste. Then, depolymerization reaction of the molten mixed polyethylene waste is started. The depolymerization reaction uses a catalyst in a high pressure reactor at a desired temperature using heaters in the high pressure reactor. The catalyst is disposed on a stirring blade. Progression of depolymerization reaction of the molten mixed polyethylene waste is allowed to continue until a pressure in the high pressure reactor reaches a desired value. The heaters are turned off and depolymerization reaction of the molten mixed polyethylene waste is stopped upon the pressure in the reactor reaching desired value. The mixed polyethylene waste is converted to wax or grease base stock.
