CATALYTIC REACTOR AND METHOD OF REALIZATION OF HIGHLY EXOTHERMIC REACTIONS Russian patent published in 1999 - IPC

FIELD: chemical technology associated with conduction of highly exothermic reactions with adiabatic heating up to 500-2500 C, for instance, hydrogenation and oxidation; applicable also in power engineering for production of hot water and steam. SUBSTANCE: tubular reactor for conduction of highly exothermic reactions combines heat-liberating and heat exchange surfaces without their separation. It has body, tube sheets, devices for introduction and withdrawal of reagents and cooling agents, catalytically active heat-exchanged tubes connected with tube sheets. Catalytically active heat-exchange tubes are metal impermeable tubes whose external surfaces are coated with layer of catalytically active reinforced porous metallic material formed by flat and corrugated bands forming bidispersed structure of layer applied to tube surface. Reacting mixture of stoichiometric or close to it compound is supplied to sheet side formed by catalytically active heat-exchange tubes, and cooling agent is supplied to inside of said tubes. The claimed invention provides for conduction of highly exothermic reactions with stoichiometric ratios of mixture and without overheating of catalytic layer. EFFECT: higher efficiency. 4 cl, 3 dwg
