Abstract
This invention relates to a process for the production of an isomerate gasoline blending component where the octane value of the isomerate is increased relative to the overall cost of the process. After isomerization, the separatory sieve of this invention selectively adsorbs unreacted normal paraffins and mono-methyl-branched paraffins but not di-methyl-branched paraffins. The preferred separatory sieve is ferrierite. This process is an improvement over prior Total Isomerization Processes (using a calcium-5A separatory sieve) to recycle only n-paraffins to the isomerization zone.
