FIELD: chemistry.
SUBSTANCE: invention relates to an ethylene synthesis method through catalytic oxidative dehydrogenation in the presence of a heterogeneous oxide catalyst containing transition metal oxides or their mixture, selected from a group containing Mo, V, Te, Nb, having oxygen retention capacity not below 0.3-0.5 mmol/g, where pure ethane is fed into a flow reactor in periodic mode through a layer of heterogeneous oxide catalyst at pressure of 1 atm, temperature of 380-500°C and volume rate of 500-30000 h-1. The reactor is then blown with carrier gas (nitrogen, argon) in short pulses for less than 20 seconds, after which air is then fed in.
EFFECT: use of the method enables to obtain ethylene via oxidative dehydrogenation of ethane with high output and safety.
