CATALYST USED FOR HYDROGEN PEROXIDE SYNTHESIS Russian patent published in 2006 - IPC C01B15/29 B01J23/42 B01J23/44 B01J31/06 

FIELD: textile, paper and chemical industries; protection of environment in production of bleachers, biocides and components of oxidizing processes.

SUBSTANCE: proposed catalyst contains one or more metals of platinum group used as active component, one or more polyolefines and activated carbon carrier. It is preferably, that polyolefines have molecular mass above 400 and are selected from ethylene homopolymers and ethylene copolymers with alpha-olefines, propylene homopolymers and propylene copolymers with alpha olefines, butadiene homopolymers and copolymers with styrene and other olefines, isoprene homopolymers and copolymers with other olefines, ethylene-propylene copolymers, ethylene-propylene diolefine three-component copolymers, thermoplastic elastomers obtained from butadiene and/or isoprene and styrene block-copolymers, both hydrogenized and non-hydrogenized. Hydrogen peroxide is produced in presence of said catalyst from hydrogen and oxygen in reaction solvent containing halogenated and/or acid promoter. Proposed catalyst makes it possible to increase degree of conversion and selectivity of process, to obtain aqueous H₂O₂ solutions at content of acids and/or salts at level of trace amount.

EFFECT: enhanced efficiency.
