OXIDATION PROCESS IN THE PREPARATION OF HYDROGEN PEROXIDE BY THE ANTHRAQUINONE METHOD

摘要

In order to carry out an oxidation enclosed circuit for the production of hydrogen peroxyde by using the anthraquinone process, according to which an oxidant gas is passed on a hydrogenated solution in a parallel-flow reactor at a temperature below 100oC, at a pressure lower than 15 bar and by increasing the reaction speed in the oxidation step, the hydrogenated solution is intensively mixed after the hydrogenation step with an oxidant gas under formation of a system inhibing the coalescence and the mixture obtained is introduced in the lower part of an essentially obstacle-free reactor wherein an almost complete reaction takes place between the oxygen and the hydroquinone present in the hydrogenated solution. The device for implementing said method comprises a mixer (1), a reactor (6) with a cleared bottom part and, if required, a distributor (7).
