Progress about thermodynamic analysis of carbon deposition in methane reforming with C-H-O triangular diagrams

Abstract

Abstract: From the perspective of thermodynamics, the carbon deposition phenomenon in methane reforming process were reviewed.The three-element composition of C-H-O triangular diagrams were analyzed, as well as various reforming forms of non-carbon deposition region, including the SMR, CDR, POM, TRM, and methane reforming process in the anode of fuel cell.Finally, the mitigate carbon deposition measures were proposed at thermodynamic perspective: the combined reforming forms can minimizes carbon deposition, while the use of anodic oxygen injection, the carbon deposition of methane reforming in fuel cells can be improved.

Key words: methane, reforming, carbon deposition, thermodynamics, fuel cell

摘要： 从热力学的角度对甲烷重整过程中的积炭现象进行了综述研究,分析了C-H-O三元素组分的积炭三角图以及不同甲烷重整形式的非积炭区域,包括了SMR、CDR、POM、TRM以及甲烷在燃料电池电化学阳极室中的重整过程。最后提出了热力学视角下缓解积炭的措施是联合重整能有效地减少积炭,而采用阳极注氧能够改善甲烷燃料电池的积炭现象。
