Abstract: A process for the double-bond isomerization of olefins is disclosed. The process may include contacting a hydrocarbon stream including olefins with a γ-alumina-titania isomerization catalyst to convert at least a portion of the olefin to its positional isomer. The γ-alumina-titania isomerization catalysts disclosed herein may also have the activity to convert alcohol into additional olefins, while having increased resistance to oxygenate poisons.
