N2 - SYNOPSIS: Catalytic steam gasification of petcoke has been studied with a pressurized fixed bed reactor. Only about 15 wt% of the coke can be gasified without any catalysts under the conditions of 750 °C, 1.0 MPa and 2 h, whereas potassium-based binary catalysts added by the impregnation method show drastic synergistic effects on coke conversion and realize the almost complete gasification accompanied by the major products of H2 and CO2. The use of these catalysts thus leads to the lowering of more than 150 °C in the gasification temperature.
