摘要
分别对甲烷与二氧化碳重整(DRM)、甲烷与水蒸气重整(SRM)、甲烷部分氧化反应(POM)和甲烷自热重整反应(ATR)四种反应中的催化剂特性、催化反应积炭问题及其挑战进行了总结,重点回顾了针对催化剂失活和积炭问题所提出的解决方案和研究进展。在不同重整反应中,催化剂的性能因具体反应条件和催化剂组成的差异而有所不同。据此,将现有解决方法归纳为三种途径:(1)使用碱性载体材料或双金属催化剂,以有效减少积炭形成并增强催化剂的稳定性;(2)采用贵金属催化剂能够显著提高催化剂的稳定性和抗积炭能力;而对于非贵金属催化剂则需要精准控制反应条件和催化剂配方以优化性能;(3)设计多相催化剂体系或具有抗烧结能力的催化剂有助于延长催化剂的使用寿命并提高反应的整体效率。
This review summarizes the catalytic properties and the challenges associated with carbon accumulation in four reforming reactions:dry reforming of methane(DRM),steam reforming of methane(SRM),partial oxidation of methane(POM),and autothermal reforming of methane(ATR).It emphasizes the research advancements aimed at mitigating catalyst deactivation and carbon accumulation.Catalyst performance varies among the different reforming reactions,influenced by specific reaction conditions and catalyst composition.The existing solutions are classified into three strategies:(1)utilizing alkaline carrier materials or bimetallic catalysts to minimize carbon deposition and enhance catalyst stability;(2)employing noble metal catalysts to improve stability and carbon resistance,while optimizing non-precious metal catalysts through precise control of reaction conditions and formulations;and(3)designing multi-phase catalyst systems or catalysts with anti-sintering properties to extend catalyst lifespan and enhance reaction efficiency.
