摘    要：积碳是影响甲烷转化制合成气的催化剂性能的重要因素。在阐述甲烷催化部分氧化过程反应机理和催化剂体系的基础上，重点论述了甲烷催化部分氧化的催化剂失活与积碳的关系及影响催化剂的积碳因素.认为提高催化剂抗积碳性能的关键在于活性组分和负载量的改变、助剂的添加、载体的调控和制备方法的改进和储氧材料的使用，并对晶格氧催化甲烷部分氧化制合成气技术提出了展望，认为该技术具有良好的工业化应用前景。

Abstract:

Carbon deposition is an important factor affecting the performance of catalyst during methane conversion to synthesis gas. This paper studies the relationship between catalyst inactivation and carbon deposition, and the factors which affect carbon deposition based on the reaction mechanism of catalytic partial oxidation of methane and catalyst system. Changing the active components and loading volume, adding addictives, regulating carrier, improving preparing method and applying oxygen storage materials are the key factors improving the ability of catalyst to resist carbon deposition. The technology of lattice oxygen catalytic by partial methane oxidation to synthesis gas has promising industry application.
