NOVELTY - Method for converting an organic material into hydrocarbon fuels, comprises pressurizing the organic material being in a fluid to a pressure above 225 bar, heating the organic material in the fluid at above 200degreesC in the presence of a homogeneous catalyst comprising a compound of an element(s) of group IA of the periodic table of elements; and contacting the organic material in the fluid with a heterogeneous catalyst comprising a compound of an element(s) of group IVB of the periodic table and/or alpha-alumina, assuring that the fluid has initially a pH of above 7.    USE - The method is useful to produce the product (I) useful: for driving a engine or generator, for power production in an oil fired power plant, for process heating or domestic heating, as a blending component in petrodiesel or gasoline, in a suspension fired system, in a process for molten mineral processing, for producing a fertilizer product and for producing clean water stream having drinking water quality (claimed).    ADVANTAGE - The process and the apparatus overcomes the difficulties of the conventional methods for treating the waste. The apparatus is cost effective.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for:    (1) a product (I) obtained by the method;    (2) an apparatus for converting an organic material into hydrocarbons, comprising: a pre-conversion system and a product recovery system (11), where pre-conversion system comprises a first heating unit (4) for heating a feed of fluid comprising organic material; a catalyst reactor (7) for contacting the feed of fluid comprising organic material, and an adjusting unit for adjusting the fluid to have a pH value of above 7, and the product recovery system comprises membrane-filter (13) for separating a first stream (L, H, O, P, E) of oils and water soluble salts in from a second stream (K, F, Q, G, R) of water and water soluble organics;    (3) a plant comprising the apparatus, for producing the product (I) by using the method; and    (4) a heterogeneous catalyst for use in a method for converting an organic material into hydrocarbons, comprising a compound of at least one element of group IVB of the periodic table and/or alpha-alumina.    DESCRIPTION OF DRAWING(S) - The figure represents the apparatus for converting an organic material into hydrocarbons:    First heating unit; (4)    Catalyst reactor; (7)    Product recovery system; (11)    Membrane-filter; (13)    First stream of oils and water soluble salts; (L, H, O, P, E)    Second stream of water and water soluble organics.
