Patent number: 7381853Abstract: 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 is particularly well suited for the production of higher olefins because of its high olefin content, low branching number, and low contaminent levels. The invention is also directed to an olefin product composition that is produced by contacting the C4+ fraction with an oligomerization catalyst. The olefin composition is characterized by a relatively high octene content, and octene with a branching number less than 1.4.Type: GrantFiled: February 22, 2005Date of Patent: June 3, 2008Assignee: ExxonMobil Chemical Patents Inc.Inventors: Luc R. M. Martens, John Stephen Godsmark, Marcel J. Janssen, Georges M. K. Mathys, Raphael F. Caers, Hubertus J. Beckers, J. Richard Shutt, Eddy Van Driessche

Patent number: 7358410Abstract: The present invention provides various processes for producing polypropylene from an oxygenate-contaminated propylene-containing feedstock, preferably derived from an oxygenate to olefin reaction system. 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 propylene in the propylene-containing stream contacts a polymerization catalyst in a polymerization zone under conditions effective to polymerize the propylene to form the polypropylene.Type: GrantFiled: March 25, 2005Date of Patent: April 15, 2008Assignee: ExxonMobil Chemical Patents Inc.Inventors: John Richard Shutt, Jeffrey L.
