Abstract:
A process for producing unsaturated carboxylic acids or unsaturated nitriles by vapor phase oxidation reaction of their corresponding C3 to C5 alkanes, C3 to C5 alkenes, and mixtures thereof, as a hydrocarbon starting material, wherein the process performance is monitored and the path of gasses through catalyst beds is altered. Improved catalyst lifetimes may be achieved.
