Process and catalyst for production of formaldehyde from dimethyl ether
Dimethyl ether is converted to formaldehyde using a supported catalyst comprising molybdenum and/or vanadium oxides. The surface density of the oxide(s) ranges from greater than that for the isolated monomeric oxides upwards, so long as there is a substantial absence of bulk crystalline molybdenum and/or vanadium oxide(s). Conversion and selectivity to formaldehyde are improved as compared to data reported for known catalysts. Also disclosed is a supported catalyst comprising molybdenum and/or vanadium oxides wherein the support comprises one or more reducible metal oxides, preferably a layer or layers of one or more reducible metal oxides disposed on the surface of a particulate alumina or zirconia support.
