PROBLEM TO BE SOLVED: To provide an improved method and an improved apparatus for converting organic materials, such as waste, sludge, and biomass etc., into recyclable products, such as hydrocarbon fuels.SOLUTION: A method for converting an organic material into hydrocarbon fuels is disclosed. The method comprises the steps of pressurizing the organic material being in a fluid to a pressure above 225 bar, and heating the organic material in the fluid to a temperature above 200°C in the presence of a homogeneous catalyst comprising a compound of at least one element of group IA of the periodic table of elements. The disclosed method further comprises the steps of bringing the organic material in the fluid into contact with a heterogeneous catalyst comprising a compound of at least one element of group IVB of the periodic table and/or α-alumina after assuring that the fluid has initially a pH value of above 7. |
