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 С₃H₈/О₂ 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.

丙烷在氢气存在下的氧化裂解

摘要

在大气压、500-750°C 的温度、2 秒的反应时间和С ₃ H ₈ /О ₂初始比率~2下，向初始混合物中添加氢气对丙烷氧化裂解参数的影响是实验性的调查。结果表明，由于形成额外的活性自由基 OH ^•和 H ^•，少量的氢会促进该过程。在大量过量氢气中进行丙烷氧化裂化导致甲烷和乙烷的产率增加，而该过程的目标产物乙烯的产率降低。
