More specifically, though not exclusively, the present invention relates to a novel method for preparing a tetrafluoropropene by dehydrohalogenating a starting or intermediate tetrafluorochloropropane and/or pentafluoropropane material in the presence of a caustic solution at a temperature range greater than 40° C. and less than or equal to 80° C.Type: GrantFiled: March 28, 2011Date of Patent: January 6, 2015Assignee: Honeywell International Inc.Inventors: Selma Bektesevic, Hsueh S. Tung, Haiyou Wang, Daniel C. Merkel, Robert C. Johnson

Patent number: 8927792Abstract: Processes for the production of chlorinated and/or fluonnated propenes provide good product yield with advantageous impurity profiles in the crude product. Advantageously, the processes may be conducted at lower temperatures than 600° C., or less than 500° C., so that energy savings are provided, and/or at higher pressures so that high throughputs may also be realized. The use of catalysts or initiators may provide additional enhancements to conversion rates and selectivity, as may adjustments to the molar ratio of the reactants.Type: GrantFiled: May 30, 2012Date of Patent: January 6, 2015Assignee: Dow AgroSciences, LLCInventors: Max M. Tirtowidjojo, William J. Kruper, Jr., Kurt F. Hirsekorn, Debashis Chakraborty

Patent number: 8927793Abstract: Processes for producing reduced acid lignocellulosic-derived pyrolysis oil are provided. In a process, lignocellulosic material is fed to a heating zone. A basic solid catalyst is delivered to the heating zone. The lignocellulosic material is pyrolyzed in the presence of the basic solid catalyst in the heating zone to create pyrolysis gases. The oxygen in the pyrolysis gases is catalytically converted to separable species in the heating zone. The pyrolysis gases are removed from the heating zone and are liquefied to form the reduced acid lignocellulosic-derived pyrolysis oil.Type: GrantFiled: July 29, 2011Date of Patent: January 6, 2015Assignee: UOP LLCInventors: Joseph Anthony Kocal, Timothy A. Brandvold

Patent number: 8927794Abstract: A process for regenerating a coked catalytic cracking catalyst which the carbon-containing deposits on the catalyst contains at least 1 wt % bio-carbon, based on the total weight of carbon present in the carbon-containing deposits is provided. Such coked catalytic cracking catalyst is contacted with an oxygen containing gas at a temperature of equal to or more than 550° C. in a regenerator to produce a regenerated catalytic cracking catalyst, heat and carbon dioxide.Type: GrantFiled: April 23, 2012Date of Patent: January 6, 2015Assignee: Shell Oil CompanyInventors: Andries Quirin Maria Boon, Johan Willem Gosselink, John William Harris, Andries Hendrik Janssen, Colin John Schaverien, Nicolaas Wilhelmus Joseph Way

Patent number: 8927795Abstract: A process for controlling the simultaneous production of hydrocarbons with boiling points in both the diesel fuel range and the aviation fuel range from renewable feedstocks originating from plants or animals other than petroleum feedstocks is described. The hydrocarbon product can be adjusted by changing the feedstocks without requiring different process equipment.Type: GrantFiled: May 18, 2012Date of Patent: January 6, 2015Assignee: UOP LLCInventors: Michael J. McCall, Timothy A. Brandvold

Patent number: 8927796Abstract: This invention discloses a process for making high viscosity index lubricating base oils having a viscosity index of at least 110 by co-feeding a ketone or a beta-keto-ester feedstock with a lubricant oil feedstock directly to a hydrocracking unit to produce a hydrocracked stream. Then at least a portion of the hydrocracked stream is treated under hydroisomerization conditions to produce a high viscosity index lubricating base oil. The process may involve bypassing a hydrotreating or hydrofinishing step, which may result in improved efficiency and economics in producing high viscosity index lubricating base oils.Type: GrantFiled: September 13, 2012Date of Patent: January 6, 2015Assignee: Chevron U.S.A. Inc.Inventors: Stephan Joseph Miller, Sven Ivar Hommeltoft, Saleh Ali Elomari

Patent number: 8927797Abstract: The method produces a hydrocarbonaceous fluid (a liquid mixture of hydrocarbons, or in other words a mixture of hydrocarbons which is liquid at ambient room temperature and atmospheric pressure), which functionally is a liquid hydrocarbon fuel, from a feed of waste plastic. The method can comprise the steps of: (step 1) melting a feed of substantially solid waste plastic in an aerobic atmosphere (for instance, air) whereby a waste-plastic melt is produced; (step 2) distilling at least a portion of the waste-plastic melt whereby a hydrocarbonaceous distillate is produced; and (step 3) collecting the hydrocarbonaceous distillate. That distillate is generally referred to above as a condensate. The method can include the step of comminuting the feed of substantially solid waste plastic into pieces substantially no greater than about 1.5 cm2 prior to step 1. The method can also include the step of adding an effective amount of a cracking catalyst to the waste plastic prior to step 2.Type: GrantFiled: February 2, 2011Date of Patent: January 6, 2015Assignee: Natural State Research, Inc.Inventor: Moinuddin Sarker

Patent number: 8927798Abstract: A new family of coherently grown composites of TUN and IMF zeotypes has been synthesized and shown to be effective catalysts for aromatic transformation reactions. These zeolites are represented by the empirical formula: NanMmk+TtAll-xExSiyOz where “n” is the mole ratio of Na to (Al+E), M represents at least one meta, “m” is the mole ratio of M to (Al+E), “k” is the average charge of the metal or metals M, T is the organic structure directing agent or agents, “t” is the mole ratio of N from the organic structure directing agent or agents to (Al+E), and E is a framework element such as gallium. The process involves contacting at least a first aromatic with the coherently grown composites of TUN and IMF zeotypes to produce at least a second aromatic.Type: GrantFiled: December 9, 2013Date of Patent: January 6, 2015Assignee: UOP LLCInventors: Christopher P.
