Publication number: 20110152062Abstract: Catalysts for experimentation are produced having a controlled matrix pore structure. The manufacturing process utilizes tape casting in the drying procedure in which a catalyst slurry is cast on a substrate and dried at a temperature of between about 50° C. to 200° C. for a period of time of about 0.1 to 1.0 hour. The dried catalyst particles can be removed from the substrate by several techniques, including scraping, burning, and deforming the substrate material, The resulting catalytic particles can be produced in an amount of about ca. 3 g to 300 g from slurries with volumes between 5 cc to 500 cc, which are suitable for small scale FCC reactors and for high throughput experimentation.Type: ApplicationFiled: December 1, 2010Publication date: June 23, 2011Applicant: EXXONMOBIL RESEARCH AND ENGINEERING COMPANYInventors: William A.

Patent number: 7799210Abstract: A three-step process of removing sulfur from naphtha feeds. The steps include a first hydrotreating step, a mercaptan removal agent and an adsorbent containing a reactive metal on an inorganic support. Step one removes at least 95 wt. % of the sulfur compounds while preserving at least 50 wt. % of the olefins. Treatment with the mercaptan removal agent lowers the sulfur content to 30 wppm total sulfur and final naphtha product contains leas than 10 wppm total sulfur.Type: GrantFiled: April 6, 2005Date of Patent: September 21, 2010Assignee: ExxonMobil Research and Engineering CompanyInventors: Jeffrey M.

Patent number: 7435335Abstract: A process for hydroprocessing a distillate stream to produce a stream exceptionally low in sulfur, with total aromatics and polynuclear aromatics being moderately reduced. A distillate stream is hydrodesulfurized in a first hydrodesulfurization stage. The product stream thereof is passed to a first separation stage wherein a vapor phase product stream and a liquid product stream are produced. The liquid phase product stream is passed to a second hydrodesulfurization stage and the product stream thereof is passed to a second separation stage wherein a vapor phase product stream and a liquid product stream low in sulfur are produced. At least a portion of the vapor product stream from said second separation stage can be cascaded to the first hydrodesulfurization stage.Type: GrantFiled: April 20, 2000Date of Patent: October 14, 2008Assignee: ExxonMobil Research and Engineering CompanyInventors: Edward S.

Patent number: 6824673Abstract: A process for producing distillate boiling range streams that are low in both sulfur and aromatics. A distillate feedstock is treated in a first hydrodesulfurization stage in the presence of a hydrogen-containing treat gas and a hydrodesulfurization catalyst, thereby resulting in partial desufurization of the stream. The partially desulfurized distillate stream is then treated in a second hydrodesulfurization stage, also in the presence of a hydrogen-containing treat gas and a hydrodesulfurization catalyst. The hydrogen-containing treat gas is cascaded from the next downstream reaction stage, which is an aromatics hydrogenation stage.Type: GrantFiled: April 20, 2000Date of Patent: November 30, 2004Assignee: ExxonMobil Research and Engineering CompanyInventors: Edward S.
