The influence of the composition of Fe and Mo oxide catalysts on their activity and selectivity in oxidation of MeOH to CH2O was investigated. The catalysts were prepared from Fe(NO3)3 and NH4 paramolybdate at pH 2 and at 70° by mixing their solutions and precipitation (or evaporation). The samples were washed, dried, heated at 110, 250, or 400° for 6 hrs., and granulated (the size 0.5-1 mm. was used in experiments). The activity and selectivity of different samples was detected in a flow-app., the concentration of MeOH in its mixture with air was 3.7%. The kinetics of the oxidation was 1st order with respect to MeOH and non-additivity of the catalytic properties of individual Fe2O3 and MoO3 in comparison with the Fe and Mo oxide catalyst was established. The highest sp. activity for the oxidation of MeOH to CH2O was found for the catalyst with the at. ratio Mo-Fe = 1.7 and an assumption was made that the active component of the catalyst was a chemical compound between Fe and Mo oxides containing about 60 at.-% Mo (1st order rate const. ksp = 3.0 cc./m.2sec.).
