NOVELTY - The method for converting organic material into hydrocarbon fuels, pressurizing the organic material in a water to a pressure of 225 bar, heating the organic material in the water to a temperature above 200degreesC in the presence of a homogeneous catalyst comprising a compound of group IA element of the periodic table of elements, contacting the organic material in the water with a heterogeneous catalyst comprising a compound of group IVB element of the periodic table and/or alpha-alumina, and/or zeolite, and assuring the water having initially a pH value of 7-9.5.    USE - Useful for converting organic material into hydrocarbon fuels by microwave excitation.    ADVANTAGE - The method effectively converts organic material and consumes less time, and is cost effective.    DETAILED DESCRIPTION - The method for converting organic material into hydrocarbon fuels, pressurizing the organic material in a water to a pressure of 225 bar, heating the organic material in the water to a temperature above 200degreesC in the presence of a homogeneous catalyst comprising a compound of group IA element of the periodic table of elements, contacting the organic material in the water with a heterogeneous catalyst comprising a compound of group IVB element of the periodic table and/or alpha-alumina, and/or zeolite, and assuring the water having initially a pH value of 7-9.5, pre-treating the organic material at a pressure of 4-15 at 100-150degreesC for a period of 0.5-2 hours, separating particles from the water having the organic material, cooling the water after contacting with the heterogeneous catalyst, separating fuel gas from the water, a second step of heating the water, filtrating the water, separating the water and water soluble organics from oil and water soluble salts in membrane-filters, recycling carbonates and/or hydrogen carbonates, alcohol and water containing hydrogen, aldehyde and/or ketone, and recirculating carboxylic acid. The heating is performed at partly by microwave heating. The conversion temperature of the organic material is heated by microwave heating, which is substantially the same in the pretreatment step (100-150degreesC). The maximum temperature of the organic material during its contact with the heterogeneous catalyst is below 175degreesC. The assuring step comprises adding a base to the water, mixing several feedstock water alkaline, adding a chemical reactant to the water, which consumes acid during pre-treatment, and raising the pH value above 7. The first step of cooling is performed by heat exchanging with a first step of heating and/or a step of pre-heating the water in the pre-treating step. The water is heated in the second step by microwave heating and/or gas phase. The water soluble organic product is recirculated to the pre-treating step. The step of contacting the organic material in the water with a heterogeneous catalyst is performed while the temperature (275-350degreesC) is kept substantially constant. The pressure for the conversion is 240-300 bar. The step of contacting is 1-5 minutes. The heterogeneous catalyst is in the form of suspended particles, tablets, pellets, rings, cylinders, a honey comb structure, and/or a fibrous structure. The heterogeneous catalyst is partly contained in a reactor. A stream of the recirculation is mixed in a ratio with a feed stream of the fluid comprising homogeneous catalyst and organic material to convert before entering the catalytic reactor. The heterogeneous catalyst is subjected to a treatment with hot pressurized water at pre-selected intervals and the treatment with hot pressurized water has duration of less than 1 hour. The organic material has subjected to a mechanical dewatering. The concentration of the carbonates and/or hydrogen carbonates is/are at 5 wt.%. The carboxylic acid comprises formic acid and/or acetic acid. The carbonate and/or hydrogen carbonate and/or alcohol and/or carboxylic acid and/or aldehyde and/or ketone is produced by the conversion of the organic material, which is re-circulated after the step of contacting the water with the heterogeneous catalyst. INDEPENDENT CLAIMS are included for:    (1) a product obtained by the method; and    (2) an apparatus for converting an organic material into hydrocarbons.
