Abstract

One promising application of supercritical water as reaction medium is the selective oxidation from methane to methanol. Methanol is one of the most important intermediates in the chemical industry with a world-wide production capacity of about 29 million tons per year (1996). A direct conversion of methane to methanol is not practicable in the gaseous phase, since the formed methanol is oxidized faster than methane. For this reason methanol is produced on the technical scale via synthesis gas route.
