Upgrading Scrap Tire Derived Oils Using Activated Carbon Supported Metal Catalysts

Abstract

Scrap tire derived oils were upgraded over metal-loaded activated carbon catalysts and commercial catalyst at different operating conditions. Activated carbon support was prepared from the pyrolytic carbon black from pyrolysis of scrap tires. Activated carbon catalysts contained the metal pairs of Co-Ni, Co-Mo, and Ni-Mo. All metal-loaded activated carbon catalysts showed similar catalytic activity for upgrading process at 350°C under hydrogen pressure of 7 MPa. However, Ni-Mo/Ac showed good catalytic activity. Liquid fuels from upgrading oils over Ni-Mo/Ac and commercial catalyst containing 45–55% of naphtha fraction, 20–25% of kerosene fraction was obtained 350°C under hydrogen pressure of 7 MPa.
