Patent number: 9399603Abstract: A process is presented for increasing the conversion efficiency of oxygenates to olefins. The conversion of oxygenates recycles unconverted oxygenates and oxygenate by-products to a second reactor unit. The present of oxygenate by-products decreases the efficiency of the methanol to olefins reaction, and passing recycled oxygenates to a second reactor unit maintains the methanol to olefins conversion efficiency while converting the by-products in a secondary zone.Type: GrantFiled: November 25, 2013Date of Patent: July 26, 2016Assignee: UOP LLCInventors: John J.

Patent number: 7914673Abstract: Disclosed is a mixer-distributor-collector apparatus for use between beds of solid particles in a fluid-solid contacting vessel. The apparatus includes a solids retaining screen, fluid deflector, passageway, fluid distributor, and flow manipulator. The flow manipulator is a device such as a honeycomb, porous solid, perforated plate, screen, or grid having an open area greater than the open area of the fluid distributor and is located below and spaced apart from the fluid distributor. The apparatus improves the fluid flow characteristics by minimizing or eliminating fluid velocity jets and/or other turbulence which can disturb the downstream particle bed. In an exemplary application, the invention finds use in simulated moving bed (SMB) adsorptive separation processes.Type: GrantFiled: October 25, 2007Date of Patent: March 29, 2011Assignee: UOP LLCInventors: Stanley J. Frey, Paul A. Sechrist, Daniel A. Kauff

Publication number: 20110004037Abstract: Methods are disclosed for the dehydrogenation of feed streams, such as in the manufacture of styrene from ethylbenzene, using a catalyst bed having catalyst with differing activities. In particular, the use of upstream and downstream catalyst beds of relatively low and high activities, respectively, can reduce the production of unwanted byproducts, especially in styrene production processes employing an oxidative reheat step (oxidation zone) prior to ethylbenzene dehydrogenation. The methods allow the maximum temperature in the oxidation zone to be decreased, thereby reducing the formation of unwanted oxygenated byproducts (e.g., phenol).Type: ApplicationFiled: June 29, 2010Publication date: January 6, 2011Applicants: UOP LLC, SUD-CHEMIE, INCORPORATEDInventors: Michael A.

Patent number: 7128829Abstract: A novel process effective for the removal of organic sulfur compounds, organic nitrogen compounds and light olefins from liquid hydrocarbons is disclosed. The process more specifically addresses the removal of these contaminants from aromatic compounds including benzene and toluene and from naphtha. The liquid hydrocarbons are contacted with a blend of at least one metal oxide and an acidic zeolite. Preferably, the metal oxide comprises nickel oxide and molybdenum oxide and the acidic zeolite is acidic stabilized zeolite Y. This blend has a significant capacity for adsorption of impurities and can be regenerated by oxidative treatment.Type: GrantFiled: May 29, 2003Date of Patent: October 31, 2006Assignee: UOP LLCInventors: Santi Kulprathipanja, Suheil F.
