【 摘 要 】

Environmental issues related to greenhouse gases (GHG) emissions have pushed the development of new technologies that will allow the economic production of low-carbon energy vectors, such as hydrogen (H₂), methane (CH₄) and liquid fuels. Dry reforming of methane (DRM) has gained increased attention since it uses CH₄ and carbon dioxide (CO₂), which are two main greenhouse gases (GHG), as feedstock for the production of syngas, which is a mixture of H₂ and carbon monoxide (CO) and can be used as a building block for the production of fuels. Since H₂ has been identified as a key enabler of the energy transition, a lot of studies have aimed to benefit from the environmental advantages of DRM and to use it as a pathway for a sustainable H₂ production. However, there are several challenges related to this process and to its use for H₂ production, such as catalyst deactivation and the low H₂/CO ratio of the syngas produced, which is usually below 1.0. This paper presents the recent advances in the catalyst development for H₂ production via DRM, the processes that could be combined with DRM to overcome these challenges and the current industrial processes using DRM. The objective is to assess in which conditions DRM could be used for H₂ production and the gaps in literature data preventing better evaluation of the environmental and economic potential of this process.
