Anthracite combustion catalyzed by Ca-Fe-Ce series catalyst

The effect of Ca-Fe-Ce series catalyst on the characteristics of anthracite combustion was investigated by thermo-gravimetric analysis. The results showed that there may be a synergetic effect among the components in the composite catalyst and the composite catalyst exhibits better performance than the single one for the anthracite combustion. The combustion characteristics of anthracite are affected by the dispersion of catalyst, heating rate and combustion atmosphere. The catalytic effect is enhanced by increasing the catalyst dispersion. The reduction degree of ignition temperature increases with the increase of heating rate. The ignition temperature decreases significantly with the increase of O₂ concentration.
