1. A process for isomerizing isoparaffins to normal paraffins comprising:
isomerizing a butane stream comprising at least about 5 mol % butanes and in which butanes comprise predominantly isobutane over an isomerization catalyst at isomerization conditions in the presence of hydrogen to increase the concentration of normal butanes at a hydrogen to hydrocarbon mole ratio at the outlet of no more than about 0.5.
