Patent number: 9844770Abstract: The application provides a catalyst for producing ethylene and propylene from methanol and/or dimethyl ether, and a preparation and application thereof. In the present application, a molecular sieve catalyst co-modified by rare earth metals and silanization is utilized.

Publication number: 20090062580Abstract: Disclosed is a method for producing a cyclic olefin compound having two or more cyclohexene rings per molecule via intramolecular dehydration of an alicyclic alcohol having two or more hydroxylated cyclohexane rings per molecule. The method includes the step (i) of heating the alicyclic alcohol at a temperature of 130° C. to 230° C. and a pressure greater than 20 Torr in an organic solvent in the presence of a dehydration catalyst, to carry out dehydration of the alicyclic alcohol while distilling off by-product water, which dehydration catalyst is liquid or soluble in a liquid reaction mixture under the reaction conditions; and the subsequent step (ii) of heating the resulting reaction mixture at a temperature of 50° C. to 220° C. and a pressure of 200 Torr or less to recover the cyclic olefin compound as a distillate.Type: ApplicationFiled: April 11, 2007Publication date: March 5, 2009Inventors: Hideyuki Takai, Kenji Oka, Kyuhei Kitao

Patent number: 7151199Abstract: Hydrocarbon or oxygenate conversion process in which a feedstock is contacted with a non zeolitic molecular sieve which has been treated to remove most, if not all, of the halogen contained in the catalyst. The halogen may be removed by one of several methods. One method includes heating the catalyst in a low moisture environment, followed by contacting the heated catalyst with air and/or steam. Another method includes steam-treating the catalyst at a temperature from 400° C. to 1000° C. The hydrocarbon or oxygenate conversion processes include the conversion of oxygenates to olefins, the conversion of oxygenates and ammonia to alkylamines, the conversion of oxygenates and aromatic compounds to alkylated aromatic compounds, cracking and dewaxing.Type: GrantFiled: June 10, 2002Date of Patent: December 19, 2006Assignee: ExxonMobil Chemical Patents Inc.Inventors: Luc Roger Marc Martens, Stephen N. Vaughn, Albert Edward Schweizer, John K. Pierce, Shun Chong Fung

Patent number: 6953873Abstract: Disclosed is a method of producing hydrocarbons from oxygenated hydrocarbon reactants, such as glycerol, glucose, or sorbitol. The method can take place in the vapor phase or in the condensed liquid phase (preferably in the condensed liquid phase). The method includes the steps of reacting water and a water-soluble oxygenated hydrocarbon having at least two carbon atoms, in the presence of a metal-containing catalyst. The catalyst contains a metal selected from the group consisting of Group VIIIB transitional metals, alloys thereof, and mixtures thereof. These metals are supported on supports that exhibit acidity or the reaction is conducted under liquid-phase conditions at acidic pHs. The disclosed method allows the production of hydrocarbon by the liquid-phase reaction of water with biomass-derived oxygenated compounds.Type: GrantFiled: May 9, 2003Date of Patent: October 11, 2005Assignee: Wisconsin Alumni Research FoundationInventors: Randy D. Cortright, James A. Dumesic
