Abstract
A combination of an etherification process and a process for the isomerization of linear alkenes to isoalkenes uses an adsorptive separation zone for olefin and paraffin separation upstream of the MTBE unit to reduce olefin losses associated with the rejection of butanes. The location of the MTBE unit downstream of the adsorptive separation zone facilitates the essentially complete removal of isobutane from the process. Supplemental rejection of isobutane downstream of the adsorptive separation permits the use of low purity adsorptive separation zone and also allows the recovery of a high purity butene-1 product.
