摘要：

Catalytic partial oxidation of methane with oxygen on several oxide supports has been studied by using a batch reactor. The reactivity of various commercial SiO2 samples at 520-degrees-C ("precipitated", "extruded", "gel" and "fumed"), expressed in terms of space time yield to HCHO, has been particularly ascertained with reference to their preparation method and sodium content. The "highest" activity of the "precipitated" SiO2 sample is further enhanced by heat-treatment at 1000-degrees-C.
