METHOD FOR PRODUCTION OF HYDROGEN PEROXIDE Russian patent published in 2017 - IPC C01B15/23 

FIELD: chemistry.

SUBSTANCE: invention relates to method and device for production of hydrogen peroxide. Method for production of hydrogen peroxide using an anthraquinone autooxidation AO process includes two alternating main stages (a) hydrogenation of working solution in a hydrogenation unit in presence of a catalyst, wherein said working solution contains at least one alkylanthraquinone, dissolved in at least one organic solvent, in order to obtain at least one corresponding alkylanthrahydroquinone compound; and (b) oxidation of said at least one alkylanthrahydroquinone compound in order to obtain hydrogen peroxide in oxidation unit; and, additionally involving stage (c) for extraction of hydrogen peroxide formed during oxidation, in an extraction unit. Stages of hydrogenation, oxidation and extraction are performed in a reactor system, which is designed as a compact modular system, consisting of a hydrogenation unit, an oxidation unit and an extraction unit, wherein said reactor system is intended for operation without a recovery (regeneration) unit, intended for continuous recovery of working solution, as low- or medium-sized AO process with hydrogen peroxide output of up to 20 kilotons a year, preferably, hydrogen peroxide output of up to 15 kilotons a year, more preferably, hydrogen peroxide output of up to 10 kilotons a year, preferably, wherein working solution and/or catalyst is replaced and/or treated for regeneration or reactivation only periodically or from time to time, for example, with low frequency.

EFFECT: technical result is production of aqueous solutions of hydrogen peroxide in concentrations, intended for use in industry, simplification and reduction of scale of process.
