Abstract

10 wt% K2CO3 supported perovskites were examined to discover their role of catalysts for effective coal gasification under 800°C. Several perovskite type supports with different amounts of Mn were synthesized by both sol-gel and modified reverse homogeneous precipitation methods. Mn effect on the coal gasification was studied. Coal catalytic gasification, its combustion as well as its activation energy were investigated by thermo-gravimetric analysis. The gasification behavior was checked and drawn out to profiles using self-designed fluidized bed reactor at 773K□1073K. Catalytic effect of Mn containing perovskite was investigated by varying the metal's contents from x=0.2 to x=1 in LaMnxCu(1-x)O3. Through the research, the optimal Mn contents for the condition were suggested. In addition, the activities of 10wt%K2CO3 supported perovskite catalysts were compared with several kinds of 10wt%K2CO3 supported Al2O3.
