Fe-0/Graphene Nanocomposite as a Catalyst for the Viscosity Reduction of Heavy Crude Oil

摘要

Fe-0/graphene nanocomposites were prepared via a thermal polymerization method and used as a catalyst to reduce the viscosity of heavy crude oil. The nanocomposites were characterized by X-ray diffraction, transmission electron microscopy, N-2 adsorption-desorption isotherms and thermal analysis. Their performance on the aquathermolysis of heavy crude oil was assessed in an autoclave. Under the reaction conditions of 200 degrees C and 24 h, the viscosity of the oil was remarkably reduced when the catalysts were added.
