In one embodiment, the process includes providing a propylene-containing stream from an oxygenate to olefin reaction system, wherein the propylene-containing stream comprises propylene and an oxygenate. The ... 08/18/05 - 20050182282 - Production of higher olefins A method of making a higher olefin product from a C4+ fraction separated from the hydrocarbon product produced by an oxygenate to olefin reaction unit. The C4+ fraction primarily contains butenes which may be directed to a higher olefin reaction unit without removing isobutenes, butanes, and/or butadiene. The C4+ fraction ... ### FreshPatents.com Support |
