Process and Reactor Consideration for Syngas Production From Natural Gas Dry Reforming

Valorization of carbon dioxide via the dry reforming of methane (DRM) reaction offers dual benefits, mitigating environmental issues and generating syngas as a valuable feedstock for the production of methanol. This chapter relates the advantages and drawbacks of the different technologies used in the dry reforming of methane, including thermally-driven, plasma-assisted, electro- and photo-assisted, membrane, and solar-driven DRM. Some technological challenges are furthermore addressed. All these processes show a promising future, but further investigations are required to overcome the major issues linked to carbon poisoning, catalyst deactivation, and energy efficiency.
