Seclective methane oxidation to organic derivatives

Michalkiewicz B.

Polish Journal of Chemical Technology

2005

Vol. 7, nr 3

77-80

Three methods of methane conversion into oxidants, excluding the stage of obtaining the synthesis gas, are known: partial catalytic oxidation over the heterogeneous catalysts, non-catalytic process of oxidation under pressure and methane esterification combined with hydrolysis. When taking into consideration the results of the studies on methane partial oxidation which have been conducted over a number of years, the last method seems to be the most promising one. The obtained ratio of methane conversion into methanol as the final product, comprises nearly 100% when the process is run in oleum, and platinum chloride (IV) acts as the catalyst.

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

Kałucki K., Michalkiewicz B.

Polish Journal of Chemical Technology

2001

Vol. 3, nr 4

16-19

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.

Partial oxidation of methane to formaldehyde over a Mo-0/Si02 catalyst

Kałucki K., Michalkiewicz M.

Polish Journal of Chemical Technology

2000

Vol. 2, nr 2

17-20

Studies on the oxidation of methane by oxygen over a Mo-O/SiO2 catalyst were performed in a vertical tubular reactor. The process was carried out over a range of temperatures from 400 to 600°C at atmospheric pressure. Both the content of oxygen in the reaction mixture and the contact time were varied. The major products of the oxidation of methane over the Mo-O/SiO, catalyst have been formaldehyde, carbon oxides, and water. The effect of temperature, contact time and methane conversion on the selectivity of methane oxidation to the respective products was studied. The mechanism of the reactions proceeding during the oxidation of methane by oxygen over this catalyst has been proposed.
