摘要：

The oxidation of CH4 with O-2 at low pressure was carried out over ZSM-5 catalysts. The H-ZSM-5 catalyst (S/A = 283) exhibited higher activities than other commercial silicas. The rate depends on the O-2 concentration, The selectivities to CH3OH are higher over Na-ZSM-5 while those to HCHO are higher over H-and Cs-ZSM-5 catalysts. The role of Si-rich ZSM-5 in the partial oxidation of CH4 was discussed. (C) 1997 Elsevier Science B.V.
