文摘A kinetic study of CH4 partial oxidation was performed using Chemkin Ⅱ simulation package with the GRI, NIST, Alexander and Leeds CH4 oxidation mechanisms. Comparing kinetic simulation results with thermodynamic analysis indicates that GRIl .2-3.0, NIST and Alexander--0. l-0.3 mechanisms give a reasonable performance in describing CH4 partial oxidation while Alexander0.4 and the Leeds mechanisms fail to do so. Two distinct reaction zones are observed in the simulation results, which is different from the two-stage concept reported in the literature.
