Dry reforming of methane (DRM) is an important technology that utilizes CO2 to convert methane to a mixture of H2 and CO (syngas). Commercial applicability of DRM has been challenged by the high energy requirement, susceptibility to coke formation, and low-quality syngas (syngas ratio, H2/CO ∼ 1). On the other hand, DRM provides an attractive pathway to the cost-effective sequestration of CO2 via transformation to value-added chemicals and fuels. DRM may be used in conjunction with other reforming technologies to produce the needed quality of syngas and to exploit synergism in energy release and demand. In this work, an optimization-based approach is used to compare the carbon footprint of conventional reforming technologies with other processes involving DRM to produce syngas of different H2/CO ratios. Technical, economic, and environmental metrics are used to assess the various options. Additionally, the model accounts for the carbon footprint associated with the reforming process, catalyst regeneration...
