Cracking of propane is expected to yield
WebAug 9, 2024 · Abstract. 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 … WebSep 1, 1986 · Thus, propane undergoes cracking into methane and ethylene by its interaction with acidic hydroxyl groups at low conversion levels, while, at higher conversion levels, it undergoes hydride abstraction by its interaction with carbenium ions.
