Catalytic Conversion of Biogas to Syngas via Dry Reforming Process

Abstract

Abstract Biogas generated from anaerobic digestion of waste biomass, primarily, contains methane and CO2, which is as an ideal renewable source for the production of syngas that is the feed stock of Fischer–Tropsch synthesis to produce fuels. Dry reforming of biogas can take full advantage of both CH4 and CO2 in biogas. Ni-based catalysts are commercially attractive due to the low cost and wide availability of Ni source. The contaminants posing and carbon formation can be delayed and suppressed by adding promoter, adopting bimetallic strategy, choosing basic support, and using appropriate catalyst preparation method, activation procedure, metal loading, and metal precursor. This chapter provides a comprehensive review of major research progress on catalytic conversion of biogas/methane into syngas and discusses the principles, catalysts, catalyst deactivation, and kinetics, with emphasis on the development of high activity and long-term stability Ni-based catalysts.
