利用固定床反应器,对标致 雪铁龙汽车公司提供的两种碳烟,在水蒸汽存在的情况下进行了低 中温燃烧(氧化)反应。进而经过数值计算和数学模拟,得出了燃烧反应的动力学参数。对于形成CO的反应,指前因子k0介于(1 55×104～3 40×107)s-1之间,活化能E介于(127 86～188 23)kJ·mol-1之间;对于形成CO2的反应,k0介于(1 68×103～4 18×105)s-1之间,活化能E介于(89 38～181 46)kJ·mol-1之间。这一结果可能为碳烟治理提供可资借鉴的基础数据。
Using fixed bed reactors, two types of soot supplied by PSA Peugeot Citroën were subjected to low and medium temperature combustion (oxidation) reactions in the presence of water vapor. Then through the numerical calculation and mathematical simulation, the kinetic parameters of the combustion reaction are obtained. For the formation of CO, the pre-exponential factor k0 is between (1 55 × 104 ~ 3 40 × 107) s-1 and the activation energy E is between (127 86 ~ 188 23) kJ · mol- The formation of CO2 reaction k0 between (1 68 × 103 ~ 4 18 × 105) s-1, activation energy E between (89 38 ~ 181 46) kJ · mol-1. This result may provide basic data for soot management.
