A carrier that has pores predominantly of two sizes is prepd. by comminuting a silica gel of pore size 2000 to 10,000 Å, mixing it with SiH4 and an aq. soln. of K2SiO3 in the ratio of 85:10:5 and drying the mixt. The carrier is then impregnated with an aq.-soln. of VOSO4 and KHSO4, dried and calcined. The product exceeds by a factor of 1.5 to 2.5 the activity of known V catalysts and exhibits activity at a temp. as low as 360°.
