Development of Monolithic Catalyst System with Co-Ru-Zr for CO2 (dry) Reforming of Methane : Enhanced Coke Tolerance

Abstract

To verify the viability of Co, Ru and Zr-based catalyst for CO2 (dry) reforming reaction, catalysts were fabricated using cordierite, silicon carbide and rota monolithic substrates, and they were compared with the conventional Co-Ru-Zr/SiO2 catalyst in terms of performance and durability. Cordierite monolith was showed high activity with the least amount of active component. In addition, when Cordierite monolith was coated with Co-Ru-Zr in various ways, most excellent performance was showed at a precursor solution coating method. In particular, when 0.9 wt% Co-Ru-Zr/Cordierite was used for reaction, it was observed that 95% CO2 conversion was maintained for 300 h at 900 ℃.
