The degradation behaviors of coke which reacts with CO2 and H2O were explored in self-made gas -solid reacting apparatus. It was observed that the temperature loss of coke with H2O in initial and violent solution were about 37 degrees C and 125 degrees C lower than that with CO2 respectively. The gasification rate of coke with H2O was about 1.27-3.16 times faster than that with CO2. But the difference of gasification rate will reduce with the lower temperature. The coke strength after reaction (CSR) with H2O was lower than with CO2 at 950 degrees C-1 100 degrees C, but higher at 1 200 degrees C. The coke's apparent porosity and changing rate after reacting were both smaller with H2O than with CO2. It is mainly due to the reaction that occurred closer to the coke particle surface with H2O than with CO2.
