  • Publication number: 20160251279
    Abstract: A process for the aromatization of alkanes in an alkane-containing gas stream comprising: contacting the alkane-containing gas stream in a reactor with a fluidized bed comprising an aromatization catalyst and a hydrogen acceptor under alkane aromatization conditions to produce a product stream comprising aromatics and hydrogen wherein the hydrogen is, at least in part, bound by the hydrogen acceptor in the reaction zone and removed from the product and the reaction zone.

  • Publication number: 20160251280
    Abstract: A process for the aromatization of alkanes in an alkane-containing gas stream, which alkane-containing gas stream contains at least one alkane selected from the group consisting of ethane, propane or butane and contains essentially no methane, comprising contacting the alkane-containing gas stream in a reaction zone with a moving bed comprising an aromatization catalyst and a hydrogen acceptor under alkane aromatization conditions to produce a product stream comprising aromatics and hydrogen wherein at least a portion of the hydrogen is bound by the hydrogen acceptor in the reaction zone and removed from the product and the reaction zone.

  • Patent number: 8927610
    Abstract: A process for the production of methane comprising reacting at least part of a feed gas containing carbon monoxide and hydrogen in an internally cooled methanation reactor containing a nickel comprising methanation catalyst to produce a product gas containing methane, cooling the internally cooled methanation reactor with water, wherein the water enters the internally cooled methanation reactor at a temperature in the range from 20-120° C. below its boiling temperature.

  • Patent number: 8470059
    Abstract: A process for producing a methane-rich gas comprising the steps of: a) mixing a feed gas, comprising carbon monoxide and hydrogen, and a recycled methane-rich gas, comprising methane, to produce a gas mixture, comprising carbon monoxide, hydrogen and methane; b) reacting at least part of the carbon monoxide and hydrogen in the gas mixture in the presence of a methanation catalyst to produce a methane-rich product gas comprising methane, carbon dioxide and water; c) treating at least part of the methane-rich product gas to remove carbon dioxide to produce a methane-rich carbon dioxide-lean gas; and d) recycling at least part of the methane-rich carbon dioxide-lean gas to mixing step a) as recycled methane-rich gas.

  • Patent number: 8461216
    Abstract: A process for the co-production of superheated steam and methane includes reacting a gas containing carbon monoxide and hydrogen in a series of methanation regions to produce a product gas containing methane The gas containing carbon monoxide and hydrogen flows, in passing through the series of methanation regions, successively through at least a first internally cooled methanation region and a second internally cooled methanation region, cooling the first and second internally cooled methanation region with water, which water is vaporized in the first internally cooled methanation region to produce steam and which steam is subsequently superheated in the second internally cooled methanation region to produce superheated steam The internally cooled methanation regions include tubes filled with a methanation catalyst and a space surrounding the tubes The gas containing carbon monoxide and hydrogen and/or product gas flows through the tubes and the water flows through the space surrounding the tubes.
