Oxidative Cracking of Propane in the Presence of Hydrogen

An effect of hydrogen additions to the initial mixture on the parameters of the oxidative cracking of propane at atmospheric pressure, temperatures of 500–750°C, reaction time of 2 s, and С 3 H 8 /О 2 initial ratio ~2 was experimentally investigated. It was shown that small amounts of hydrogen promote the process due to the formation of additional active radicals OH • and H • . Performance of the oxidative cracking of propane in a large excess of hydrogen results in an increase in the yield of methane and ethane, while the yield of ethylene, the target product of the process, decreases.
