Intrinsic kinetics of lean methane catalytic combustion on coated noble HPA(KMK) catalyst

The experimental investigation of methane catalytic combustion on coated noble catalyst was carried out,using an integral micoreactor under the condition free of external and internal diffusion limitations.Forty-five groups of experimental data for methane conversion were obtained under different space velocities and temperatures.The partial least-square(PLS)and The Nelder-Mead simplex search methods were employed to estimate the parameters of the intrinsic model.The intrinsic model of lean methane catalytic combustion on the HPA(KMK) catalyst is rA=7.32×109 exp(-64 550RT)CA.The parameters obtained are consistent with the Physical-Chemical rules and statistically reasonable.
