摘要

摘要: 二氧化碳甲烷化（Sabatier反应）是载人航天再生式环控生保系统中空气质量管理的关键技术，也是焦炉气甲烷化和煤制天然气甲烷化流程中最后一级反应器主要进行的化学反应.化工行业中的二氧化碳甲烷化，尤其是针对高纯度二氧化碳的甲烷化技术，与载人航天用Sabatier技术既有共同点又存在差异.通过对Sabatier技术工艺、催化剂和关键设计的总结，对比分析应用于两个不同领域的二氧化碳甲烷化技术在工艺流程、催化剂和反应器方面的差异，借鉴工业二氧化碳甲烷化技术经验，提出载人航天用Sabatier技术可能的优化方向.

Abstract: Carbon dioxide (CO₂) methanation (Sabatier reaction) is one of the key techniques of air quality management in the manned space Environmental Control and Life Support System (ECLSS). Meanwhile, the same carbon dioxide methanation technology is also used in coal chemical industry. The carbon dioxide methanation reaction mainly occurs at the last stage of coke oven gas methanation process and coal-to-substitute natural gas methanation process, using carbon dioxide methanation catalyst. Great progress has been made in China's industrial methanation technology in recent years. The technology for industrial high purity carbon dioxide maybe helpful for the research of Sabatier technology used in spacecraft. In view of the latest development of industrial methanation technology, the Sabatier reaction and the industrial carbon dioxide methanation technology are summarized and compared, from three aspects including CO₂ methanation process, catalyst and reactor, and suggestions for the research of Sabatier technology in manned spacecraft are given.
