  • Patent number: 9844770
    Abstract: 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. First, the material containing methanol and/or dimethyl ether reacts on the catalyst to generate hydrocarbons. The hydrocarbons are separated into a C1-C5 component and a C6+ component. Then the C6+ component is recycled to the feeding port and fed into the reactor after mixing with methanol and/or dimethyl ether. The above steps are repeated, to finally generate C1-C5 products, in which the selectivity for ethylene and propylene can reach more than 90 wt % in the C1-C5 component, so that the maximal yield can be achieved in the production of ethylene and propylene from methanol and/or dimethyl ether.

A process for conversion of a lignin material to bio-fuels can include subjecting the lignin material to a base catalyzed depolymerization reaction to produce a partially depolymerized lignin. The partially depolymerized lignin can then be subjected to a stabilization/partial hydrodeoxygenation reaction to form a partially hydrodeoxygenated product. Following partial hydrodeoxygenation, the partially hydrodeoxygenated product can be reacted in a hydroprocessing step to form a bio-fuel. Each of these reaction steps can be performed in single or multiple steps, depending on the design of the process. The production of an intermediate partially hydrodeoxygenation product and subsequent reaction thereof can significantly reduce or eliminate reactor plugging and catalyst coking.

  • Patent number: 7772450
    Abstract: In a process for converting methane to syngas and aromatic hydrocarbons, a feed containing methane is contacted with a dehydrocyclization catalyst under conditions effective to convert said methane to aromatic hydrocarbons and produce a first effluent comprising aromatic hydrocarbons and H2, wherein said first effluent comprises at least 5 wt % more aromatic hydrocarbons than said feed. At least part of the H2 from said first effluent is then reacted with an oxygen-containing species, such as carbon dioxide, to produce a second effluent having an increased H2 and CO content compared with said first effluent.

  • Patent number: 7759535
    Abstract: In a process for converting methane to higher hydrocarbons including aromatic hydrocarbons, a feed containing methane is contacted with a dehydrocyclization catalyst under conditions effective to convert said methane to aromatic hydrocarbons and produce a first effluent stream comprising aromatic hydrocarbons and hydrogen, wherein said first effluent stream comprises at least 5 wt % more aromatic hydrocarbons than said feed. At least part of the hydrogen from said first effluent stream is then reacted with an oxygen-containing species, such as carbon dioxide, to produce a second effluent stream having a reduced hydrogen content compared with said first effluent stream.

  • Publication number: 20090062580
    Abstract: 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.

  • Patent number: 7151199
    Abstract: 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.

  • Patent number: 6953873
    Abstract: 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.
