  • Publication number: 20160039855
    Abstract: A method of recovering oleagineous compounds from hydrothermally treated biomass, including providing a biomass feedstock as an aqueous biomass suspension and processing the biomass suspension at a reaction temperature and a reaction pressure for a reaction time in a reactor to produce a product mixture is provided. In a separation step, die product mixture is contacted with an extraction fluid comprising at least one extraction, agent selected from the group consisting of mono-aromatic hydrocarbons, monoaromatic alcohols and monoaromatic ethers to obtain an organic liquid phase that contains at least a part of the oleagineous compounds. Use of at least one corresponding extraction agent in a method of recovering oleagineous compounds from hydrothermally treated biomass is also subject of the invention.

  • Patent number: 8623624
    Abstract: The invention relates to a method for biotechnological production of a hydrogen carrier. It is proposed to culture ammonium-producing cyanobacteria in which, by increasing the nitrogenase activity and/or blocking the utilization of ammonium in the cell metabolism and/or providing an exit mechanism for ammonium via the cell membrane, the ammonium yield is increased. The ammonia generated by the cyanobacteria is made available as a hydrogen carrier.

  • Patent number: 4343633
    Abstract: In the purification of a hydrogen stream contaminated with at least methane and ethane, e.g. a hydrogen cycle gas from a coal hydrogenation process, where the hydrogen stream is subjected to multistage partial condensation and separation of the respectively formed condensates, the improvement of subjecting the hydrogen stream under a pressure of above about 100 bar to the multistage partial condensation and separation of having in the final condensate 5-40 molar percent of ethane, thereby favorably altering the K-value of methane and its ease of removal from the hydrogen which is only altered in the manner desired when the process is conducted under pressures in excess of about 100 bar.
