| Abstract: | The gasification of Yining long flame coal char,with CO2 serving as the gasifying agent,had been studied by TG under the catalysts,such as K2CO3,Na2CO3,KOH and CaO.The results showed that:(1) with the adding of 10% K2CO3,the gasification time was shortened by 9.2min,and the corresponding gasification temperature was decreased by 184℃;(2) The optimum of Na2CO3 was 5%;(3) the catalytic activity order of these catalysts were K2CO3>KOH > Na2CO3>CaO. |
