The kinetics of the water-gas shift (WGS) reaction over a novel La0.7Ce0.2FeO3 perovskite-like catalyst is investigated using simulated coal-derived syngas at temperatures of 550 degrees C and 600 degrees C which are higher than the maximum operating temperature limit for conventional high temperature WGS catalysts. The influences of CO, CO2, H2O and H-2 concentration on WGS reaction rate are determined using selected gas compositions that might be encountered in a coal-based gasification system. An empirical power-law rate model used in this study is found to correlate well with experimental data with good accuracy. Kinetics parameters over La0.7Ce0.2FeO3 obtained in this study are mostly in agreement with those previously measured using Fe-Cr based commercial catalysts in a range of relatively lower temperatures (300-500 degrees C).
