摘要
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。
It deals with low temperature combustion (oxidation) of soots from diesel engine provided by (Citrn) PSA at the presence of water vapor in this paper.Numerical calculation and mathematical imitation were carried out upon experimental results.Kinetics,like pre-exponential factor(k_0) and apparent activation energy(E) were concluded.It indicates that k_0 for CO formation reaction is between (1.55×10^(4)～(3.40×10^(7))) s^(-1),and E is between (127.86～188.23) kJ·mol^(-1).Meanwhile,k_(0 ) for formation of CO_(2) is between (1.68×10^(3)～4.18×10^(5)) s^(-1),E is between (89.38～181.46) kJ·mol^(-1).These facts will probably be found application in fixation of control measures for abatement of soots from diesel engine.
