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: 8993821Abstract: A new family of crystalline aluminosilicate zeolites has been synthesized that has been designated UZM-43. These zeolites are similar to previously known ERS-10, SSZ-47 and RUB-35 zeolites but are characterized by unique x-ray diffraction patterns and compositions and have catalytic properties for carrying out various hydrocarbon conversion processes. Catalysts made from these zeolites are useful in hydrocarbon conversion reactions.Type: GrantFiled: December 18, 2012Date of Patent: March 31, 2015Assignee: UOP LLCInventors: Deng-Yang Jan, Jaime G. Moscoso, Paula L. Bogdan

Patent number: 8993823Abstract: A process for the metathesis of olefins has been developed. The process comprises contacting a hydrocarbon feedstock with a catalyst at metathesis conditions. The catalyst comprises a tungsten compound, which contains at least one tungsten-fluoro bond, dispersed or grafted onto a support. A specific example of the catalyst is the compound WOF(CH2CMe3)3 grafted onto a silica support. The feedstock comprises a first and a second olefin wherein the second olefin has a carbon number of at least two greater than the first olefin and the product is an olefin with a carbon number intermediate between the first and second olefin. Specifically the process produces propylene from ethylene and butylene.Type: GrantFiled: June 25, 2014Date of Patent: March 31, 2015Assignee: UOP LLCInventors: Mostafa Taoufik, Etienne Mazoyer, Christopher P. Nicholas, Jean-Marie Basset

Patent number: 8993824Abstract: One exemplary embodiment can be a process for fluid catalytic cracking. The process may include providing a first feed having a boiling point of about 180-about 800° C. to a first riser reactor, and providing a second feed having first and second parts to a second reactor. Typically, the first part includes one or more C5-C12 hydrocarbons and a second part includes one or more C4-C5 hydrocarbons. Generally, an effective amount of the second part is combined with the first part to maximize production of propene.Type: GrantFiled: September 28, 2011Date of Patent: March 31, 2015Assignee: UOP LLCInventor: Robert L. Mehlberg

Patent number: 8993825Abstract: An aromatics complex producing one or more xylene isomers offers a large number of opportunities to conserve energy by heat exchange within the complex. One previously unrecognized opportunity is through providing two parallel distillation columns operating at different pressures to separate C8 aromatics from C9+ aromatics. The parallel columns offer additional opportunities to conserve energy within the complex through heat exchange in associated xylene recovery facilities.Type: GrantFiled: May 21, 2014Date of Patent: March 31, 2015Assignee: UOP LLCInventors: Gregory R. Werba, Jason T. Corradi, Xin X. Zhu, David W. Ablin, Saadet Ulas Acikgoz, Phillip F. Daly

Patent number: 8993826Abstract: Methods for converting toxic waste, including nuclear waste, to quasi-natural or artificial feldspar minerals are disclosed. The disclosed methods may include converting, chemically binding, sequestering and incorporating the toxic waste into quasi-natural or artificial Feldspar minerals. The quasi-natural or artificial feldspar minerals may be configured to match naturally occurring materials at a selected disposal site. Methods for the immediate, long term, quasi-permanent disposal or storage of quasi natural or artificial feldspar materials are also disclosed.Type: GrantFiled: October 5, 2012Date of Patent: March 31, 2015Inventor: Dimitre S. Assenov

Patent number: 8993827Abstract: A method and apparatus for the stabilization and safe removal of buried waste that is tested and classified as being transuranic or not transuranic waste and disposed accordingly. The buried waste (usually in vertical pipe units) is enclosed in a casing and ground and mixed with the surrounding soil. This process allows for chemical reactions to occur that stabilizes the mixture. The entire process is contained within the casing to avoid contamination. In situ or external testing is done for radio isotopes to classify the waste. If it is classified as transuranic the waste is removed in a controlled way into a retrieval enclosure and disposed off in drums. If the waste is not transuranic then grout is introduced into the mixture, allowed to set and the resulting monolith is removed and buried in trenches.Type: GrantFiled: November 16, 2012Date of Patent: March 31, 2015Assignee: VJ TechnologiesInventors: Boris Soyfer, Steve Halliwell, Keith Stone
