ABSTRACT:
A combination of an etherification process and a process for the isomerization of linear alkenes to isoalkenes uses an adsorptive separation zone that receives an effluent fraction from the etherification reaction zone and separates the fraction at low efficiency to produce an isomerization feed stream comprising normal butenes and butanes, and a butane stream that is rejected from the process. The rejection of butanes at low efficiency reduces or eliminates the loss of butenes with the rejection of butane. A low efficiency adsorptive separation to reject butanes also benefits the isomerization process by inhibiting coking.
