Abstract

The selective oxidation of 1,3-butadiene and furan to maleic anhydride over NiMoO4 catalysts containing excess MoO3 was investigated. Activity and selectivity measurements were performed using a fixed-bed, integral reactor system. The results were compared with those obtained for 1-butene oxidation which indicated the most selective component of the catalyst for maleic anhydride formation was a MoO3 phase having a surface covering of NiMoO4; similar results were found to be applicable for 1,3-butadiene and furan oxidation. NiMoO44 was determined to be the catalyst component responsible for oxidative dehydrogenation of 1-butene; this phase also selectively blocked complete oxidation sites on MoO3, thereby changing the selectivity in favor of maleic anhydride.
