Publication number: 20120125814Abstract: A process for reforming a feed composed of one or more hydrocarbon cuts containing 9 to 22 carbon atoms comprises: at least one first step for reforming the feed in at least one reforming unit, during which a stream of hydrogen is produced; at least one first step for distillation of the effluent from the reforming unit in the presence of a reforming catalyst in order to obtain 4 cuts: a liquefied petroleum gas cut (LPG) (A); a C5-C8 cut: naphtha (B); a C9-C15 cut: densified kerosene (C); a C16-C22 cut: densified gas oil cut (D). The invention also concerns the device for carrying out this process. FIG. 1 to be published.Type: ApplicationFiled: October 26, 2011Publication date: May 24, 2012Applicant: IFP ENERGIES NOUVELLESInventors: Eric SANCHEZ, Jacques RAULT, Pierre Yves LE GOFF, Christophe PIERRE, Joana FERNANDES

Patent number: 8148288Abstract: The invention relates to a catalyst that comprises a metal M from the group of platinum, at least one promoter X1 that is selected from the group that consists of tin, germanium, and lead, and optionally at least one promoter X2 that is selected from the group that consists of gallium, indium and thallium, a halogenated compound and a porous substrate, in which the atomic ratio X1/M and optionally X2/M is between 0.3 and 8, the Hir/M ratio that is measured by hydrogen adsorption is greater than 0.40, and the bimetallicity index BMI that is measured by hydrogen/oxygen titration is greater than 108. The invention also relates to the process for the preparation of this catalyst and a reforming process using said catalyst.Type: GrantFiled: December 7, 2007Date of Patent: April 3, 2012Assignee: IFP Energies NouvellesInventors: Pierre-Yves Le Goff, Fabienne Le Peltier, Jean Giraud, Sylvie Lacombe, Christophe Chau

Publication number: 20120067774Abstract: Processes for increasing overall aromatics and xylenes yield in an aromatics complex are provided. A C8+ aromatics stream from an aromatics-rich reformate is separated into a C8 aromatics fraction and a C9+ aromatics fraction comprising higher alkyl group-substituted C9 and C10 aromatics. The C9+ aromatics fraction is separated into a lighter boiling, higher alkyl group-substituted C9 or C9/C10 aromatics fraction and a heavier boiling, C10+ or C11+ aromatics fraction. The lighter boiling, higher alkyl group-substituted C9 or C9/C10 aromatics fraction is isomerized to convert a portion of the higher alkyl group-substituted C9 or C9/C10 aromatics therein into methyl-enriched C9 aromatics or methyl-enriched C9/C10 aromatics. The methyl-enriched C9+ aromatics stream comprising the methyl-enriched C9+ aromatics stream or the methyl-enriched C9/C10 aromatics is transalkylated with a toluene-containing stream.Type: ApplicationFiled: September 16, 2010Publication date: March 22, 2012Applicant: UOP LLCInventors: Stanley J. Frey, Jason T. Corradi, Gregory Werba

Publication number: 20120024754Abstract: The present invention relates to a multistage reforming process to produce a high octane product. A naphtha boiling range feedstock is processed in a multi-stage reforming process, in which said process involves at least 1) a penultimate stage for reforming the naphtha feedstock to produce a penultimate effluent 2) a final stage for further reforming at least a portion of the penultimate effluent 3) a regeneration step for the final stage catalyst. The severity of the penultimate stage can be increased during final stage catalyst regeneration in order to maintain the target RON of the reformate product and avoid reactor downtime.Type: ApplicationFiled: July 28, 2010Publication date: February 2, 2012Inventors: Cong-Yan Chen, Stephen J. Miller, James N. Ziemer, Ann J. Liang
