Chapter 8 - Dry reforming of methane and biogas to produce syngas: a review of catalysts and process conditions

Abstract

Dry reforming reactions produce syngas, which is the main feed to produce value-added chemicals and fuels via Fischer-Tropsch synthesis. Along with SOx and NOx, CO2 and methane are parts of the greenhouse gases that have a significant impact on the ecosystem. Therefore, proper mitigation and utilization of CO2 and methane in dry reforming would reduce greenhouse gas emissions. Dry reforming of methane and biogas has gained huge attention because of the abundance of natural gas. Several studies have focused on designing catalysts with higher catalytic activity and stability toward coke deposition, which is the main challenge in dry reforming reactions. In this chapter, various heterogeneous catalysts are evaluated for dry reforming. Furthermore, the effects of catalyst components, catalyst preparation methods, and the impact of reforming process conditions on the catalytic activity and coke deposition are discussed.
