| 摘 要： | 利用热天平研究了Ca-Fe-Ce系催化剂对无烟煤燃烧特性的影响。结果表明,复合催化剂中各个组分之间具有一定的协同作用，其催化效果优于单一催化剂。升温速率、分散程度、燃烧气氛等因素对催化无烟煤燃烧特性具有明显的影响：升温速率越快，催化燃烧时燃点降低得越多；催化效果随着催化剂在煤粉分散程度的增加而增加；氧气浓度越大，催化剂使煤的燃点降低越明显。

| Abstract: | 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 incre... |
