Ru-containing RUA and Ni-containing FCR-4 were tested as tar reforming catalysts. Toluene was used as the model tar at both standard and high concentrations. Both catalysts effected over 90% conversion at 800 °C for standard toluene loading. Conversion increased with steam content and decreased as space velocity increased. FCR-4 showed significantly greater coke deposition, accounting for deactivation.
