Abstract
Carbon-supported Mo2C nanoparticles were synthesized and used as catalysts for the deoxygenation of oleic acid and soybean oil to produce diesel-range hydrocarbons. Various carbon materials, such as reduced graphene oxide (RGO), glassy spherical carbon (SC), activated carbon (AC), and mesoporous carbon (MC), were used as supports to determine the effects of RGO in the deoxygenation reactions. The effects of the flow rate, Mo content of the catalyst, and the structure of the carbon support on the conversion and product selectivity were investigated. The morphology analysis revealed that Mo2C nanoparticles were well-dispersed onto the RGO (Mo2C/RGO). Under moderate reaction condition (T = 350 °C, P = 5.0 MPa, H2/oil ratio = 4.5, LHSV = 2 h–1), oleic acid was efficiently deoxygenated using the Mo2C/RGO catalyst, which produced hydrocarbons with ≥85% yield and ≥90% hydrocarbon selectivity. This value was much higher than those obtained using the Mo2C/SC, Mo2C/AC, and Mo2C/MC catalysts (yields = 18.5–50.3%) un...
