Flyash as Support for Ni Catalysts in Carbon Dioxide Reforming of Methane

A series of Ni catalysts supported on flyash treated by various chemical methods was tested for carbon dioxide reforming of methane. Ni catalyst on the flyash treated with CaO (Ni/Ash-CaO) shows high conversion and stability, being close to those of the well-reported Ni/A12O3 and Ni/SiO2 catalysts with conversions approaching thermodynamic equilibrium levels.
