Promotion of V-P Oxide Catalyst for Butane Oxidation by Metal Additives

Article abstract of DOI:10.1246/cl.1992.13

Mixed oxide catalyst V-P-O for the butane oxidation to maleic anhydride was significantly promoted by the addition of some metal cations.In paricular, the addition of a small amount of Bi (Bi/V = 0.02) was the most effective.Over the Bi-added catalyst, the MA selectiviy exceeded 70 molpercent up to the butane conversion level of 88 molpercent, attaining the maximum MA yield of 62 molpercent at 395 deg C.
