    Abstract: A method of continually heat-treating a biogenic material in the production of fuels such as ethanol or biogas includes pressurizing the biogenic material with a first pump so as to provide a pressurized suspension. The pressurized suspension is continuously heat-treated at a heat-treatment temperature of from 100° C. to 180° C. in a hydrolysis reactor so as to provide a heat-treated suspension. A temperature of the heat-treated suspension is lowered to below 100° C. The heat-treated suspension is depressurized with a second pump. The first and second pumps are configured to maintain at least one of the pressurized suspension and the heat-treated suspension at a pressure of above 5 bar.

    Abstract: A light olefin feed for an olefin utilization process is subjected to a water wash to remove water-soluble contaminants after which the water is separated from the olefin by coalescence separation at a low temperature, typically below 40° C. The coalescence separation technique is effective for separating the olefins from the water with its dissolved contaminants. If desired, a supplemental washing may be carried out by adding additional water to the feed/water mix after the initial wash step but before the coalescer in order to remove provide additional contaminant removal.

  • Publication number: 20100228067
    Abstract: The present invention generally relates to the conversion of sugars and/or other biomass to produce hydrocarbons, hydrogen, and/or other related compounds. In one aspect, the invention includes fermenting biomass to produce one or more organic intermediates, for example, a carboxylic acid, and optionally, hydrogen. The carboxylic acid may then be decarboxylated to produce CO2 and one or more hydrocarbon compounds, for example, an alkane or an alkene, such as propane or ethylene. Such reactions can occur, in some cases, under hydrothermal conditions, and in some instances, without the use of or need for electrolysis of the reactants. In some cases, for example, if the carboxylic acid (or other organic intermediate) includes a hydroxide moiety, the carboxylic acid may be dehydrated, i.e., reacted such that the hydroxide moiety is removed from the molecule as H2O.

  • Publication number: 20100087695
    Abstract: Surface-active solid-phase catalyst activity may be substantially improved by creating deliberate repetitive surface-to-surface contact between portions of the active surfaces of catalyst objects. While they are immersed in reactant material such contact between portions of the active surfaces of catalyst objects can substantially activate the surfaces of many heterogeneous catalysts. Examples are given of such action employing a multitude of predetermined shapes, supported catalyst structures, etc. agitated or otherwise brought into contact to produce numerous surface collisions. One embodiment employs a gear pump mechanism with catalytically active-surfaced gear teeth to create the repetitive transient contacting action during pumping of a flow of reactant. The invention is applicable to many other forms for creating transient catalytic surface contacting action. Optionally catalytic output of such systems may be significantly further improved by employing radiant energy or vibration.

  • Publication number: 20030045765
    Abstract: The present invention relates to a process for manufacturing alkanes. comprising, as main stage, a reaction resulting from bringing methane into contact with at least one other starting alkane (A) in the presence of a catalyst based on a metal M capable of catalysing a metathesis of alkanes. The reaction results in the formation of at least one or two final alkanes (B) having a number of carbon atoms less than or equal to that of the starting alkane (A) and at least equal to 2. Preferably the catalyst comprises a hydride of a metal M grafted to and dispersed over a solid support. The metal M may be chosen from transition metals, lanthanides and actinides. The present invention also relates to the use of a catalyst capable of catalysing a metathesis of alkanes in a reaction resulting from bringing methane into contact with at least one other starting alkane (A).

  • Patent number: 6469225
    Abstract: A process for the manufacture of alkanes comprising a cross-metathesis reaction between at least one starting alkane (A) and one organometallic compound (B) fixed to an inorganic support and comprising a metal bonded to at least one hydrocarbon-comprising radical. The reaction leads to the formation of at least one other alkane (C) which is a higher or lower homologue of the starting alkane (A), by cleavage of the hydrocarbon-comprising radical with the metal of the organometallic compound (B) and recombination of the radical with at least one other radical originating from a cleavage of the starting alkane (A). The metal of the compound (B) preferably is selected from transition metals, lanthanides and actinides, and the hydrocarbon-comprising radical of the compound (B) preferably is selected from alkyl, alkylidene and alkylidyne radicals.

  • Patent number: 6410814
    Abstract: A process for synthesis of lower isoparaffins from synthesis gas that is a mixture of hydrogen and carbon monoxide, wherein straight chain hydrocarbons are synthesized while isoparaffins and isoolefins are also produced through decomposition of hydrocarbons having a higher carbon number by use of a solid acid catalyst in the first stage, and isoparaffins are synthesized in the second stage. The straight chain hydrocarbons are produced by contacting the synthesis gas with a Fischer-Tropsch synthesis catalyst that is mixed with a solid acid catalyst for mainly hydrocracking long chain hydrocarbons. The isoparaffins are produced by contacting the straight chain hydrocarbons synthesized in the first stage, with a mixture of a hydrogenation catalyst for hydrogenating olefins and a solid acid catalyst for hydrocracking and isomerizing the straight chain hydrocarbons.

    Abstract: Disclosed is a process for opening naphthenic rings of naphthenic ring-containing compounds, along with catalysts which can be used in that process. The ring opening is accomplished using a ring opening catalyst system which combines an Ir ring opening catalyst with a Pt and Pd catalyst. The combination of the Pt and Pd-containing catalyst with an Ir-containing catalyst incorporates desirable isomerization activity and also results in substantial ring opening activity that enables Ir to be loaded at a level that is substantially below that of Ir-only ring opening processes.
