Abstract
1440149 V-P-O catalytic compound MONSANTO CO 6 Feb 1974 [7 Feb 1973] 05447/74 Heading C1A [Also in Divisions B1 and C2] A catalyst composition comprises phosphorus and vanadium in combination with oxygen, wherein the P/V atomic ratio is 1 : 2 to 2 : 1, more than 50% atom of the vanadium is in the tetravalent state and the composition is in the form of structures of a porosity of at least 35%. The composition may be formed by contacting vanadium and phosphorus compounds under conditions giving more than 50 atom per cent of vanadium in the tetravalent state; recovering a catalyst precursor and forming it into structures; calcining to give a precatalyst containing not more than 80% atom of the vanadium in the pentavalent state and then passing a saturated hydrocarbon admixed with a free oxygencontaining gas through the precatalyst at elevated temperature. In an example 2% of graphite is added to the prepared catalyst before tabletting.
