Pozdnyakov *Khristianovich’s Institute of Theoretical and Applied Mechanics SB RAS, Novosibirsk, 630090, Russia **Institute of Chemical Kinetics and Combustion SB RAS, Novosibirsk, 630090, Russia We studied the hitherto proposed method of hydrocarbons pyrolysis in a flow of a high- temperature heat carrier, wherein the pyrolyzed feedstock jets are injected by the normal to the reactor’s axis. The fundamental schematic of the process is presented. The experimental facility developed in accordance with the proposed concept is described. The experiments were performed with the propane as pyrolyzed feedstock, and products of hydrogen-air mixture combustion used as the heat carrier. The results of experiments and numerical simulation demonstrated the promising future of the developed method of pyrolysis. As the initial mixture temperature was increased up to 1400 R, the yield of ethylene increased essentially comparing to the traditional pyrolysis method. The required length of reactor reduced about one order. In [1, 2] the new model of the high-temperature pyrolysis of hydrocarbons in the high- temperature heat carrier flow is proposed. The heat accumulated in the heat carrier should be enough to enable
