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.
