Abstract: PROBLEM TO BE SOLVED: To provide a method of double bond isomerization for olefine that can maintain a higher activity over the entire lifecycle of catalyst.SOLUTION: A method of double bond isomerization for olefine is disclosed. The method may comprise contacting a fluid flow comprising olefine with a fixed bed that comprises an activated basic metal oxide isomerization catalyst having an effective diameter in the range of 0.25 mm to 4.0 mm, in order to convert at least a part of the olefin into its isomer. The isomerization catalyst disclosed in the present specification may reduce the deactivation between cycles as compared with conventional catalysts and therefore maintains a high activity over the entire lifecycle of catalyst.

Abstract: A process for the double-bond isomerization of olefins is disclosed. The process may include contacting a fluid stream comprising olefins with a fixed bed comprising an activated basic metal oxide isomerization catalyst to convert at least a portion of the olefin to its isomer. The isomerization catalysts disclosed herein may have a reduced cycle to cycle deactivation as compared to conventional catalysts, thus maintaining higher activity over the complete catalyst life cycle.
