Procedure

A fresh sample of niobium promoted VPO catalyst (prepared similarly to the other VPO catalyst used herein but with niobium added during the catalyst preparation) was tested in a 1.5″ diameter steel fluidized bed reactor to determine maleic anhydride yield. The sample was tested at the conditions. Butane conversion and maleic anhydride yield was as listed in Table 1. Note that the yield is higher than for the catalysts in Comparative Examples 2-5.
