| 摘 要： | 研究了两种燃烧方式煤燃烧过程中金属铜的添加对多环芳烃生成的影响。结果表明:随着铜煤质量比的增加,管式炉煤燃烧多环芳烃生成浓度是减少的;流化床煤燃烧多环芳烃生成浓度是增加的,但要小于管式炉条件下两个数量级。多环芳烃生成毒性分布类似于多环芳烃生成浓度分布。而单个多环芳烃生成有着较大区别,同燃烧方式、存在状态、铜的含量等有较大关系。在燃烧温度下,铜的添加主要对高环物质的催化作用较为明显。

| Abstract: | The influence of copper on PAHs formation from coal combustion under two different combustion condition was studied. The results show that: PAHs formation during fixed bed coal combustion decreases with increasing (Cu/Coal)m, while it has a reverse trend during fluidized bed coal combustion. Quantitatively, PAHs formation during fluidized bed coal combustion is two-order less than that of fixed bed coal combustion. The toxicity of PAHs has a similar distribution with PAHs formation. But the formation of individual PAH has a great difference and be correlate with combustion condition, forms in existence and copper content. Copper has a positive influence as catalyst on high-ring PAHs. |
