Selective methane oxidation over promoted oxide catalyst. Quarterly report, September--November 1993
Dispersed metal oxide catalysts have been prepared and tested for selective oxidation of methane. The catalysts were based on multivalent cations impregnated into a number of different oxide supports: MoO{sub 3}/SiO{sub 2}, V{sub 2}O{sub 5}/SiO{sub 2}, V{sub 2}O{sub 5}/MoO{sub 3}/SiO{sub 2}, V{sub 2}O{sub 5}/TiO{sub 2}, SnO{sub 2}/SiO{sub 2}, and V{sub 2}O{sub 5}/SnO{sub 2}. Among the dispersed metal oxide catalysts studied this quarter, the most active catalyst was clearly the V{sub 2}O{sub 5}/SiO{sub 2} catalyst. High surface area silica samples impregnated with 1--5 wt% V{sub 2}O{sub 5} were found to be active catalysts with low selectivity toward CO{sub 2}. Although CO was the major product, appreciable selectivities toward formaldehyde were also observed. Indeed, with the V{sub 2}O{sub 5}/SiO{sub 2} catalysts, very high space time yields of formaldehyde of > 1 kg CH{sub 2}O/kg catal/h could be obtained even though conventional single pass %yields were <2%. These results were obtained at relatively high GHSV (70,000--280,000 {ell}/kg catal/h) but moderate temperatures (530--630C).
