FIELD: heat exchange.
SUBSTANCE: invention relates to a device for catalytic processing of light hydrocarbon fractions, which includes a recovery heat exchanger, a heater and isothermal catalytic reactors, equipped with each heating unit. At that, the heater is the first "raw material / circulating heat carrier" heat exchanger, the oxidation unit is installed as the heating unit, separated by a heat-conducting partition from a catalyst arranged in the catalysis unit, and equipped with a system for leveling the concentration of the oxidised substrate along the surface of the partition wall, wherein catalytic assembly is located on line of raw material after second heat exchanger "raw material / circulating heat carrier", recuperative heat exchanger and first heat exchanger "raw material / circulating heat carrier" and is equipped with catalyst outlet line through recuperative heat exchanger, and the oxidation unit is located on the circulating heat carrier line, on which the first heat exchanger "raw material / circulating heat carrier" is successively located, heat recovery heat exchanger, second heat exchanger "raw material / circulating heat carrier" and gas blower, additionally to oxidation unit adjoins line of oxidised substrate supply, and line of circulating heat carrier is adjoined to lines of air inlet and outlet of balance heat carrier.
EFFECT: proposed device allows to increase raw material conversion and reduce heat losses.
