FIELD: chemistry.
SUBSTANCE: invention relates to chemistry and represents methods and devices for stimulating endothermic reactions in gas phase with high activation barriers by means of a pulsed nanosecond electric discharge. Plasma-chemical reactor with generation of a pulsed nanosecond electric discharge comprises one or more cylindrical channels having a gas inlet system and a gas outlet system; high voltage positive electrode and a high voltage negative electrode in each channel and a gas vortex system in each channel to increase the local tangential velocity of the gas near the ends of the electrodes; in which pulse electric discharge with frequency f is generated, and tangential gas velocity is more than f*5*10-4 m/s.
EFFECT: increasing energy efficiency of energy transfer from power supply unit to plasma and service life of electrode.
