Large volume of gases that have reacted is cooled and recirculated with fresh gas mixture to repress heat development. It may be 100 times the fresh gas. A small fraction of the reacted gas is strongly cooled to obtain reaction products. Thus 700 m.³ per hr. at 20 atm. was introduced and 70,000 m.³ recirculated. Temperature was 320° at the entrance and 330° at the outlet. 96 kg. solid, liquid, and gaseous products were obtained: 17 kg. CH₄ and ethane, 20 kg. ethene and C₃-C₄ alkenes, 42 kg. gasoline b. 200° , 10 kg. middle oil, 1 kg. solid paraffin, 6 kg. ethanol.
