The main goal of this study was to investigate the effect of chemical parameters on the reaction of methane oxidation. Partial oxidation of methane on silica suported molybdena catalyst has been studied. The chances of an increase of oxygenates yield in partial oxidation of methane to the economically efficient level were investigated. Two kinds of tests were performed: methane oxidation on MoO3/SiO2 catalyst with an addition of hydrogen and water vapour to the reaction mixture. The most profound promoting effect was exhibited by water vapour addition. The optimum selectivity toward methanol formation was found at the reaction temperature around 575 - 650°C. The physico - chemical properties of the catalyst were determined using different techniques: N2 adsorption, SEM and FT-IR.
