The present invention relates to a bio oils and molybdenum carbide catalyst, and a manufacturing method used for the process for producing the hydrocarbons, particularly diesel range hydrocarbons from the reaction can cheomtal oxygen from the fatty acid free standing thereto. Molybdenum carbide supported catalyst according to the present invention can make easy access to the molybdenum carbide nanoparticles in high dispersion by the supercritical fluid can be obtained, a hydrocarbon group of high yield than from organic oxygen compounds, In addition, the catalysts as described above without the use of a sulfur compound, such as the conventional catalyst for the activation process and the performance of maintenance, and therefore, can cheomtal do not discharge the sulfur components in the oxygen reaction detected, and environmentally friendly, typically caused by the intense part reactivity of the conventional noble metal catalyst it is possible to reduce the consumption of hydrogen by the water gas shift reaction or a methanation reaction as it is economical effect. Furthermore, by making the renewable fuel does not contain oxygen, in addition to the conventional gasoline or diesel engine, it is possible to solve the problem caused by the conventional use of FAME current biodiesel.
