摘要： 为了实现减缓气候变化的全球性目标，人类在减少CO2的净排放方面做出了重要努力。一方面，以固体基材料吸附为例，二氧化碳捕集技术可以从焚烧炉、水泥制造厂、燃烧厂、发电厂等排放的废气中提取二氧化碳。另一方面，二氧化碳可以转化为有用的化学物质，例如，用适当的多相催化剂加氢制甲烷。目前，一项相对创新的方法是通过材料和工艺的合理设计来耦合以上两种技术，并通过在捕集和甲烷化两种模式之间的循环切换来实现二氧化碳的减排和资源化利用。这种方法可以实现复杂组分废气中二氧化碳的选择性循环捕集，和适当条件下二氧化碳的催化加氢转化。本文简要的介绍了近年来文献中报道的这种二氧化碳捕获耦合甲烷化(CCCM)工艺的主要技术方案。我们讨论了不同类型的反应器配置，并介绍了在此背景下作为吸附剂、甲烷化催化剂和“双功能材料”使用的配方。

Abstract: Considering the global objective to mitigate climate change, import efforts are made on decreasing the net emission of CO2 from gas effluents. On the one hand CO2 capture—for example by adsorption onto solid basic materials—allows to withdraw CO2 from the waste gas streams emitted by incinerators, cement manufacture plants, combustion plants, power plants, etc. On the second hand, CO2 can be converted to useful chemicals—e.g. hydrogenation to methane—using appropriate heterogeneous catalysts. A relatively innovative strategy consists in combining both technologies by designing materials and processes which can switch between capture and methanation modes cyclically. This allows treating complex waste gas effluents by selectively and reversibly capturing CO2, and to perform the catalytic hydrogenation in appropriate reaction conditions. This short review presents the main strategies recently reported in the literature for such combined CO2 capture and methanation (CCCM) processes. We discuss the different types of reactor configurations and we present the formulations used in this context as adsorbent, as methanation catalysts, and as “dual functional materials”.
