HCHO was prepd. by oxidn. of MeOH with air by passing the gaseous reaction mixt. through an Fe-Mo catalyst. In order to increase the yield and to reduce the costs, a 2.3-2.5:1 Mo-Fe catalyst of particle size 3-4 mm was placed in the 1st bed and a 1.7-1.8:1 Mo-Fe catalyst of particle size 1-2 mm was placed in the last bed.
