铜锰负载型堇青石整体催化剂表面低浓度甲烷催化燃烧本征动力学研究

摘要

Intrinsic kinetic studies of the catalytic combustion of lean methane over a Cu-Mn/cordierite catalyst have been carried out in an integral reactor under the following conditions; p = 0. 1 MPa, t = 600 - 700 ℃ and feed composition y( CH4 ) =0. 1% -1%. The kinetic model parameters were estimated by means of the Simplex optimal method. Statistical tests and residual distribution results showed that the kinetic model derived is acceptable and reliable.%采用等温积分反应器,在常压、600～700℃和甲烷体积分数0.1％～1％的条件下,对国产铜锰负载型堇青石整体催化剂上低浓度甲烷催化燃烧本征动力学特性进行了系统的实验研究.以单纯形法对动力学实验数据进行最优化参数估计,建立了低浓度甲烷催化燃烧双曲型本征动力学模型,数理统计和残差分布检验结果表明,所建模型与实验结果良好相容,是适宜和可信的.
