The important task of gas chemistry is processing of refinery gases of composition which can vary significantly at various oil refineries. The work is devoted to the development of scientific foundations for a new method of refinery gas processing, the first stage of which is the oxidative cracking of hydrocarbons that are the part of refinery gases into valuable products with a high added value. Experimental studies of oxidative cracking of ethane and its mixtures with ethylene were carried out in a flowing quartz reactor. Experiments were made at pressures of 1 to 3 atm, temperatures from 500 to 750 °C, reaction time of 2 s, and initial C/O ratio in the range of 2.3 to 2.5 (α = 0,115–0,124) using mixtures diluted with nitrogen. Differences in the reactivity of ethane and ethylene at the oxidative stages of the process for these conditions are identified.
