Publication number: 20080262282Abstract: A process for producing para-xylene from a hydrocarbon feed is described in which an adsorption column operating as a simulated moving bed with at least five zones delivers an extract, a 2-raffinate and an intermediate raffinate. The extract is distilled and the distillate is optionally re-crystallized to recover para-xylene with a purity of at least 99.7%. The 2-raffmate is distilled then isomerized in a reactor preferably operating in the liquid phase and at a low temperature. The intermediate raffinate with an enriched ethylbenzene content is distilled then isomerized in the vapour phase.Type: ApplicationFiled: November 23, 2004Publication date: October 23, 2008Inventors: Philibert Leflaive, Luc Wolff, Gerard Hotier

Patent number: 6140547Abstract: An isomerization process for converting an isomerization feed stream containing alkanes having about 4 carbon atoms to about 10 carbon atoms per molecule and cycloalkanes having about 5 carbon atoms to about 10 carbon atoms per molecule to at least one product hydrocarbon isomer. The isomerization feed stream, which contains at least one feed hydrocarbon and hydrogen, is contacted in an isomerization zone at effective isomerization conditions with a catalyst where deactivation of such catalyst occurs in the isomerization zone. The isomerization process includes the presence of an additive in the isomerization feed stream. The concentration of the additive is sufficient to alleviate or diminish the deactivation of the catalyst and to maintain a substantially constant conversion of the at least one feed hydrocarbon to the at least one product hydrocarbon isomer at effective isomerization conditions.Type: GrantFiled: December 1, 1998Date of Patent: October 31, 2000Assignee: Phillips Petroleum CompanyInventors: Fan-Nan Lin, Edgar D.
