Abstract
A process for the production motor fuel components from isoparaffins by dehydrogenation, oligomerization and saturation uses a combination of low severity dehydrogenation, first and second feed input locations and a primary separation column that receives feed and effluent components to deliver a dehydrogenation zone feed and a motor fuel products. A separation column receives the an isobutane input stream and a product containing effluent stream to distill a dehydrogenation zone input steam. The dehydrogenation zone operates at low severity conditions to produce the effluent stream that compliments the operation of an oligomerization zone by delivering an effluent stream that is higher in pressure and contains inert paraffinic diluent materials. The oligomerization effluent passes to a saturation reaction zone that provides a saturated effluent stream. The saturation zone effluent is divided to provide quench to both the oligomerization reaction zone and the saturation zone and saturated motor fuel components to the separation column.
