Catalytic Effects of Fe 3 O 4 /GLC Nanocomposites for Pyrolysis of Heavy Oil

The paper studied the effects of Fe 3 O 4 nanoparticles loaded biomass-derived carbon (Fe 3 O 4 /GLC) from ginkgo leaf on catalytic pyrolysis of heavy oil for the first time, and which was synthesized via green and low-cost ball milling method. The properties of Fe 3 O 4 /GLC were characterized by XRD, SEM, EDS, TEM, XPS. The experimental results showed that the viscosity of heavy oil may be decreased by 79.06% under optimal pyrolytic conditions of 350°C, 30 min and 0.05 wt % catalyst, and the viscosity reduction rate increased by 18.93% compared with pyrolysis alone. The property of the used catalyst was consistent with the new catalyst by XRD analysis. It was suggested that the catalyst had high activity and high stability for catalytic upgrading and viscosity reduction of heavy oil.
