自放热条件下甲烷部分氧化制合成气

Partial Oxidation of Methane to Syngas by Self exothermic Reaction

天然气组成的９０％以上是甲烷．目前由天然气制合成气的主要方法是水蒸汽重整法，这种方法投资大、设备复杂、能耗高、生产的合成气不适于直接用来合成甲醇和烃类等．甲烷部分氧化可直接制得Ｈ２与ＣＯ摩尔比为２的合成气，这是一个温和的放热过程、具有大空速和低温等优...

The partial oxidation of methane to syngas by self exothermic reaction has been studied over Ni/ZrO 2 catalyst. It is found that the Ni content in catalyst had little effect on the activity and selectivity of the catalyst and increase of space velocity and reaction temperature improved the methane conversion and the selectivity of CO and H 2.
