Abstract
The effects of sulfation on iron oxides prepared from goethite and ferrihyd rite for methane oxidation have been investigated. Reaction performance has been shown to be influenced by the iron oxide precursor. Sulfation produce s a number of general effects, in addition to enhancing catalyst surface ar ea, it suppresses the oxidation activity of Fe2O3 observed at 400 degrees C and below, whilst enhancing that at higher temperatures. Selective partial oxidation products - CH3OH and C2H6 - are also observed in some instances with sulfated systems.
