- Abstract
- Catalytic hydroprocessing of oxygen-containing plastic waste: polyethylene terephthalate and polycarbonate were carried out. A catalyst based on nickel phosphide containing crystalline phases of Ni2P and Ni(PO3)2 was obtained in situ during the co-processing of these plastics. The catalyst was studied using powder X-ray diffraction and X-ray photoelectron spectroscopy. As a result of quantitative processing of plastics over the catalyst, aromatic C6–C10 hydrocarbons were obtained with a selectivity up to 89% at 400°C, an initial hydrogen pressure of 9 MPa, and a reaction time of 6 hours.
