A skeletal isomerization process for isomerizing olefins is described. The process utilizes added hydrogen as a diluent to extend the isomerization catalyst's lifetime and increase the yield of skeletal isomer products compared to process that utilize inert gas diluents. The methods of this disclosure can be applied to feeds containing iso-olefins (for the production of linear olefins) or linear olefins (for the production of iso-olefins).
