The effect of boron and magnesium additives on catalytic perform of Mo-0/Si02 in the partial oxidation of methane

The effect of boron or magnesium additive to the catalyst containing molybdenum oxide on the methane conversion and the selectivity of methane oxidation to the particular products have been investigated. It has been found that the boron used as an additive, elevated the selectivity of methane oxidation to formaldehyde. The highest methane conversion wasobtainet over the Mo-0/SiO2 catalyst. For the catalysts with additives, the conversion was low. Both boron and magnesium allow the elimination of the oxidation reaction of carbon monoxide to carbon dioxide.
