Abstract
Favorable isomerization conditions for producing normal paraffins can produce olefins. The process for separating normal paraffins from non-normal paraffins by adsorption has a limit on olefin concentration, so the olefins must be removed. We propose to remove olefins from the isomerization effluent stream that is recycled to the adsorption separation process.
