摘要: “温室效应”已经成为人类面临的重要挑战之一。在许多造成“温室效应”的气体中,CO2占总效应的60%–70%,因其热力学性质稳定且化学惰性强而难以转化,会长期影响气候环境。CH4占温室气体总效应的20%。尽管CH4浓度低,但单个CH4分子对“温室效应”的贡献值是CO2的25倍左右。人们一直在寻找降低大气中CO2和CH4浓度的方法,其中CO2-CH4重整反应不仅能够实现该目标,应对气候问题,同时还获得高附加值产品,因而具有重要的理论意义和实用价值。

Abstract: The greenhouse effect poses one of the significant challenges to humanity. Among the various greenhouse gases, CO2 accounts for 60% to 70% of the total contribution. Importantly, CO2 is thermodynamically stable and chemically inert, making its conversion a difficult task. Moreover, CO2 emissions will have a long-term impact on the environment. On the other hand, CH4 contributes approximately 20% to the overall greenhouse effect. Despite its relatively low concentration, a signal CH4 molecule has a global warming potential 25 times greater than that of a CO2 molecule. To mitigate the increasing concentrations of CO2 and CH4, many efforts have been developed. Among these, the reforming of CH4 and CO2 to syngas is a promising approach. This process not only helps in addressing climate change but also enables the production of value-added chemicals. In this respect, this reaction holds important theoretical significance and practical value.
