Abstract
A method for reducing the benzene content and isomerizing at least a portion of a C.sub.5 /C.sub.6 paraffinic stream using a hydrogen stream containing more than 0.1 ppmv of carbon monoxide, carbon dioxide or a mixture thereof, the method comprising: charging a C.sub.5 /C.sub.6 paraffin stream containing benzene to a benzene saturation zone; charging a hydrogen stream containing at least 0.1 ppmv of at least one carbon oxide to the benzene saturation zone; saturating at least a major portion of the benzene and methanating at least a major portion of the carbon oxide present in the benzene saturation zone to produce a reduced benzene content C.sub.5 and C.sub.6 paraffinic stream and a reduced carbon oxide content hydrogen stream; recovering the reduced benzene content C.sub.5 and C.sub.6 paraffinic stream and 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 C.sub.5 /C.sub.6 isomerization zone; charging at least a portion of the reduced benzene content …
