【摘要】 本文在管式炉上研究了煤中氯对多环芳烃生成的影响,测定了煤中氯含量不同时多环芳烃生成量的变化,并分析了在不同气氛下不同含氯量的煤燃烧时多环芳烃与二(?)英生成的相互关系.实验结果表明,在空气中燃烧及氮气气氛热解条件下,随着氯含量的增加,多环芳烃呈减少趋势;氯代反应是导致多环芳烃生成量减少的一个主要原因.更多还原

【Abstract】 The influence of coals with different chloride content to polycyclic aromatic hydrocarbons (PAHs) formation is investigated in a tube furnace. The production of PAHs is measured from different chloride content of coal combustion process, and the relation between the PAHs and dioxin is analyzed. The results show that the formation of PAHs decreases with the increasing of chloride content in coal during coal combustion in air and pyrolysis in N2. The chloridization is the main reason for the decrease of PAHs.更多还原
