Investigation of reaction mechanism in the partial oxidation of methane to synthesis gas

甲烷部分氧化制合成气的反应机理探索姜玄珍（化学系）近年来，甲烷部分氧化制合成气（ＣＯ＋Ｈ２）成为十分吸引人的课题［１－３］。因为它（ＣＨ４＋１／２Ｏ２→ＣＯ＋２Ｈ２……（１），△Ｈ＝－８．５ｋｏａｌ．ｍｏｌ－１）是温和放热反应，所制合成气之比Ｈ２／Ｃ...

he previously proposed reaction mechanism in the partial oxidation of methane to syntesis gas have been examined in the present study.It was more complex than previous thought. Both carbon dioxide and carbon monoxide were able to be formed directly from methane as primary product.It depends on the nature of the support of catalyst. The behaviour of reaction was associated with the occurence of a chain reaction which was initiallied by free radicals. The activation of methane,rather than oxygen activation,was found to be arate controlling step in overall reaction.
