钼酸盐对卷烟燃烧氧化反应的催化作用

Study on the Catalysis of Molybdate on Oxygenolysis of Cigarettes Combustion

用自动吸烟机、气相色谱、高效液相色谱和电子自旋波谱分别检测钼酸盐处理的卷烟和对照卷烟的燃烧速度、烟气焦油量、焦油中BaP和自由基的浓度 ,用差热分析和热失重分析探讨反应机理。结果表明 :钼酸盐添加剂对降低卷烟燃烧反应的活化能、提高卷烟的燃烧速度、降低烟气焦油量。

Determination of the combustion rate, tar in smoking gas, BaP in tar and the free radicals consistency of tobacco cut sample (one has added molybdate and the contrast has not) by auto smoking mechanism, gas chromatography, high performance liquid chromatography and electron spin resonance spectroscopy. The combustion reaction by differential thermal analysis and thermogravimetry analysis. The result shows that molybdate addition has effect on reducing the activation energy of cigarettes combustion, accelerating the combustion rate, reducing the tar in smoking gas, BaP in tar and free radicals.
