NOVELTY - Manufacturing hydrocarbon fuels and oxygenated hydrocarbon fuels comprises: forming a mixture of reactants comprising a carbonaceous material of hexoses, pentoses, polysaccharides, and/or lignocelluloses, water, a metal catalyst and an acid, and reacting the mixture in the presence of hydrogen at 25-200 degrees C for a time sufficient to produce a furan type hydrocarbon fuel.    USE - The methods are useful for: manufacturing hydrocarbon fuels and oxygenated hydrocarbon fuels; manufacturing furan derivative liquid fuel; and conversion of a lignocellulose to a furan type fuel (all claimed).    ADVANTAGE - The method is carried out in a single step    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for:    (1) manufacturing furan derivative liquid fuel from biomass derived carbohydrate comprising: forming a mixture of reactants comprising a carbonaceous material of fructose, glucose, inulin, sucrose, cellulose, xylose, a metal catalyst, an acid, and/or an organic solvent; and reacting the mixture under hydrogen at an elevated temperature for 4-20 hours to produce a furan derivative fuel;    (2) a method of conversion of a lignocellulose to a furan type fuel comprising, forming a mixture comprising a lignocellulose, metal catalyst, water, acid, alkali halide salt and aromatic solvent, reacting the mixture in hydrogen at a pressure of 30-500 psi at 80-200 degrees C to produce a furan fuel; and    (3) a method of continuous manufacture of a furan type fuel comprising: (a) forming a reaction mixture of a carbonaceous material, acid, water and metal catalyst; (b) reacting the mixture under hydrogen at elevated temperature for a time sufficient to generate a reaction product comprising a furan type fuel, acid, water and metal catalyst; (c) combining the reaction product with an aromatic solvent to form a solvent blend having the fuel on it; (d) removing the solvent layer having the fuel on it from the reaction product; (e) adding additional amount of carbonaceous material to form a second reaction mixture; and (f) repeating steps (a)-(e).
