Zusammenfassung:	Apparatus for the integrated oxidation and supercritical gasification of aqueous organic waste. The invention pertains to the technical field of the treatment of organic waste and to the field of energy recovery from waste with a high concentration of organic material by oxidation and supercritical water gasification. The invention allows aqueous waste with a high concentration of organic material to be purified in an oxidation reactor, and part of the heat generated by strongly exothermic reactions is transferred through the wall of the reactor to an outer casing in which another aqueous stream of organic waste under high-pressure is circulated and heated until endothermic gasification reactions are produced to generate fuel gases (mainly hydrogen). The reactor and the casing thereof form a device similar to a heat exchanger with concentric tubes in which the heating fluid is separate from the cooling fluid. Aparato para tratamiento integrado de oxidación y gasificación supercritica de residuos acuosos orgánicos. La invención se encuadra en e¡ sector técnico del tratamiento de residuos orgánicos y en el sector energético de valorización de residuos con elevada concentración de materia orgánica, mediante los procesos de oxidación en agua supercritica y gasificación en agua supercritica. Permite depurar un residuo acuoso con elevada concentración materia orgánica mediante un reactor de oxidación, y parte del calor debido a las reacciones fuertemente exotérmicas, se transmite a través de su pared hacia una carcasa exterior por donde circula otra corriente acuosa de residuos orgánicos a alta presión y se calientan hasta llevar a cabo reacciones endotérmicas de gasificación que generan gases combustibles (principalmente hidrógeno). El reactor y la carcasa forman un dispositivo similar a un intercambiador de calor de tubos concéntricos, en el que el fluido calefactor es independiente del fluido refrigerante.
