FIELD: chemistry.
SUBSTANCE: invention relates to device, which includes recuperative heat exchanger, heater, at least, two isothermal catalytic reactors, which work alternately in mode of processing and regeneration of catalyst, as well as heat-carrier heater, lines of raw material supply, catalyst output and intra-device technological lines. In the process of devices operation light hydrocarbon raw material is heated in recuperative heat exchanger and processed in isothermal catalytic reactor, heated by heat-carrier, obtained catalysate is cooled in recuperative heat-exchanger and put out of device. Heat-carrier is obtained in heater by air oxidation of fuel and regeneration gas, waste gas is discharged from device. Oxidative catalyst regeneration is realised by blowing catalyst in reactor, which is in mode of regeneration, with oxygen-containing gas, at temperature of regeneration, obtained regeneration gas is supplied into heater.
EFFECT: continuity of device operation and reduction of its fire-explosion hazard.
