A reactor for hydrothermal oxidation treatment of an organic material in a reaction medium, comprising: a confinement member housed in a chamber and defining a confinement zone and a peripheral zone; at least one inlet for an oxidising fluid into the peripheral zone; a first cooling system, with an external circulation cold loop having a fluid inlet and outlet, opening into a first portion of the peripheral zone; a heating system, with an external circulation hot loop having a fluid inlet and outlet opening into a second portion of the peripheral zone; a channel with a mouth, a channel stirring system; a second cooling system for creating a temperature gradient along the channel between a cold temperature and the reaction temperature; each circulation loop being equipped with a circulator and with a heat exchanger.

Reactor for the hydrothermal oxidation treatment of an organic material in a reaction medium

A reactor for treating an organic material in a reaction medium by hydrothermal oxidation, comprising: a longitudinal body provided with a cold interface flange; an inner tube, positioned in the body to form an annular area and comprising a cold end and a hot end, the inner tube delimiting an internal reaction area in fluid communication with the annular area via an opening provided in the hot end of the inner tube; blades for stirring the reaction medium situated in the internal reaction area and mounted rotating about the longitudinal axis of the body; a sleeve for injecting organic material to be treated into the inner tube. The inner tube is mounted rotating on the cold flange, so as to be rotated about the longitudinal axis; the sleeve being positioned inside the inner tube, having a bore that defines a passage for the organic material to be treated to pass.
