Abstract
A method for isomerizing at least a portion of a butane stream using a hydrogen stream containing more than 0.1 ppmv of carbon monoxide, carbon dioxide or a mixture thereof, the method comprising: charging the hydrogen stream containing at least 0.1 ppmv of at least one carbon oxide to a aromatics saturation zone to produce a reduced carbon oxide content hydrogen stream; recovering the reduced carbon oxide content hydrogen stream; drying at least a portion of the reduced carbon oxide content hydrogen stream to produce a dried reduced carbon oxide content hydrogen stream; charging at least a portion of the dried reduced carbon oxide content hydrogen stream to a butane isomerization zone; charging the butane stream to the butane isomerization zone; and, isomerizing at least a portion of the butane to produce an isobutane stream.
