Coprocessing of heavy shale oil with polyethylene waste

As the pyrolysis of heavy oil yields much coke and gas under the optimum temperature for PE destruction (450 °C), a two-stage pyrolysis is proposed. In the first stage the destruction of single PE is carried out at 450 °C. In the second stage the PE oil obtained is added to the heavy oil, and their copyrolysis is carried out with 5% of D as catalyst under the hydrogen atmosphere.
