Patent number: 8993818Abstract: Technologies to convert biomass to liquid hydrocarbon fuels are currently being developed to decrease our carbon footprint and increase use of renewable fuels. Since sugars/sugar derivatives from biomass have high oxygen content and low hydrogen content, coke becomes an issue during zeolite upgrading to liquid hydrocarbon fuels. A self-sustainable process was designed to reduce the coke by co-feeding sugars/sugar derivatives with the paraffin products from hydrogenation of sugars/sugar derivatives. Paraffins without complete conversion result in products with less aromatics and relatively low density compared with the products directly from zeolite upgrading. Thus, the process is more economically favorable.Type: GrantFiled: August 22, 2011Date of Patent: March 31, 2015Assignee: Phillips 66 CompanyInventors: Yun Bao, Edward L.

Patent number: 8962905Abstract: Process for the continuous hydrogenation of triglyceride containing raw materials in a fixed bed reactor system having several catalyst beds arranged in series and comprising at least one hydrogenation catalyst comprising an active phase constituted by a nickel and molybdenum element. The raw material feed, hydrogen containing gas and diluting agent are passed together through the catalyst beds at hydrogenation conditions. The raw material feed stream as well as the stream of hydrogen containing gas are divided into an equal number of different partial streams. These are each passed to one catalyst bed in such a manner that the weight ratio of diluting agent to raw material feed is essentially the same at the entrance of all catalyst beds and does not exceed 4:1. The claimed process is preferably conducted at low temperatures and allows the utilization of existing units due to the low recycle ratio.Type: GrantFiled: September 7, 2011Date of Patent: February 24, 2015Assignee: IFP Energies NouvellesInventors: Thierry Chapus, Nathalie Dupassieux, Antoine Daudin

Patent number: 8664459Abstract: A process for hydrogenating olefins is disclosed. The olefins are present in a feed gas which includes H2 and one or more sulfur compounds. The sulfur compounds may include H2S and organic sulfur compounds. The feed gas is passed through a reactor at an inlet temperature from 100° C. to 250° C. The reactor contains a catalyst which is active at the inlet temperature. The reactor may be adiabatic. Saturated hydrocarbons are formed from the olefins. A temperature gradient may be formed in the reactor due to the exothermic nature of the hydrogenation reaction, causing the temperature to increase downstream in the reactor. At temperatures higher than the inlet temperature, H2S may be formed from organic sulfur compounds. A gas mixture including saturated hydrocarbons, H2S and H2 exits the reactor and may be brought into contact with a chemical adsorbent which removes the H2S. The gas stream may then be passed to a steam methane reformer.Type: GrantFiled: November 4, 2008Date of Patent: March 4, 2014Assignees: Air Products and Chemicals, Inc., Johnson Matthey PLCInventors: Ruth A.

Publication number: 20090048473Abstract: ITQ-34 (INSTITUTO DE TECNOLOGÍA QUÍMICA number 34) is a new crystalline microporous material with a framework of tetrahedral atoms connected by atoms capable of bridging the tetrahedral atoms, the tetrahedral atom framework being defined by the interconnections between the tetrahedrally coordinated atoms in its framework. ITQ-34 can be prepared in silicate compositions with an organic structure directing agent. It has a unique X-ray diffraction pattern, which identifies it as a new material. ITQ-34 is stable to calcination in air, absorbs hydrocarbons, and is catalytically active for hydrocarbon conversion.Type: ApplicationFiled: December 4, 2007Publication date: February 19, 2009Inventors: Avelino Corma, Maria Jose Diaz, Fernando Rey, Jose Luis Jorda Moret

Publication number: 20090018374Abstract: A hydrogenation catalyst particularly suitable for hydrogenating oxygenates in a hydrogenation unit of a Fischer-Tropsch plant is disclosed. A preferred embodiment comprises more than 5% and less than 20% nickel based on a wide pore alumina support. The catalyst successfully hydrogenates oxygenates which otherwise tend to poison a catalyst in a hydroconversion unit downstream. Moreover, the temperature at which the unwanted hydrogenolysis of long chain paraffins to methane occurs is higher for one catalyst disclosed herein than a comparable known catalyst. This allows the hydrogenation plant to operate at a higher temperature.Type: ApplicationFiled: January 23, 2006Publication date: January 15, 2009Inventors: Focco Cornelis Bijlsma, Jan Lodewijk Maria Dierickx, Arend Hoek, Frans Joris Antonius Kellendonk, Anna Elisabeth Maria Oud

Publication number: 20080275145Abstract: A catalyst including cobalt, zinc oxide and aluminium is described, having a total cobalt content of 15-75% by weight (on reduced catalyst), an aluminium content ?10% by weight (based on ZnO) and which when reduced at 425° C., has a cobalt surface area as measured by hydrogen chemisorption at 150° C. of at least 20 m2/g cobalt. A method for preparing the catalyst is also described including combining a solution of cobalt, zinc and aluminium with an alkaline solution to effect co-precipitation of a cobalt-zinc-aluminium composition from the combined solutions, separating of the co-precipitated composition form the combined solutions, heating the composition to form an oxide composition, and optionally reducing at least a portion of the cobalt to cobalt metal. The catalysts may be used for hydrogenation reactions and for the Fischer-Tropsch synthesis of hydrocarbons.Type: ApplicationFiled: April 15, 2005Publication date: November 6, 2008Inventors: John Leonello Casci, Carl Leonard Huitson, Cornelis Martinus Lok
