Abstract:
In one embodiment, the invention is to a catalyst composition comprising vanadium, titanium; and at least one oxide additive. The at least one oxide additive is present in an amount of at least 0.1 wt % based on the total weight of the catalyst composition. The molar ratio of titanium to metal additive in an active phase of the catalyst composition is at least 0.05:1.
