摘要：

We have studied partial oxidation of methane on V2O 5/SiO2 (0.8 mass % V) in a flow-through catalytic fixed-bed reactor. We found that the methane/air ratio in the starting reaction mixture has practically no effect on the selectivity of the process. The dependence of the selectivity on the methane conversion can be described by a model with such reaction parameters as the initial selectivity and the relative reactivity (with respect to methane) of the reaction products. ©2002 Plenum Publishing Corporation.
