  • Publication number: 20090305355
    Abstract: The present invention relates to methods for syngas-production from biomass enabling the conversion of pre-treated biomasses having a high dry-matter content into electricity or oil-based products such as petrol, diesel, chemicals and plastics through the formation of syngas. The biomasses are converted into a biomass slurry having a suitable particle size and dry-matter content for optimal feeding and gasification in a pressurised gasifier.

  • Patent number: 7598069
    Abstract: Disclosed are processes for liquefaction and saccharification of polysacharide containing biomasses having high dry matter content (>20%) and preferably possessing large average particle size. The polysaccharide containing biomasses are subject to enzymatic hydrolysis in a mixer that utilizes “free fall” mixing. “Free fall” mixing provides mechanical degradation of the biomass during hydrolysis and, in the case of lignocellulosic biomass, promotes movement of cellulase enzymes along cellulose chains, which improves enzymatic hydrolysis at high dry matter.

  • Publication number: 20090004714
    Abstract: The present invention relates to a process for production of fermentation products, including bioethanol by non-pressurised pre-treatment, enzymatic hydrolysis and fermentation of waste fractions containing mono- and/or polysaccharides, having a relatively high dry matter content. The process in its entirety, i.e. from non-pressurised pre-treatment over enzymatic hydrolysis and fermentation to sorting of fermentable and non-fermentable solids can be processed at a relatively high dry matter content in a single vessel or similar device using free fall mixing for the mechanical processing of the waste fraction.

  • Publication number: 20080138862
    Abstract: The present invention relates to a process for liquefaction and saccharification of polysaccharide containing biomasses, having a relatively high dry matter content. The present invention combines enzymatic hydrolysis with a type of mixing relying on the principle of gravity ensuring that the biomasses are subjected to mechanical forces, primarily shear and tear forces. Furthermore, the present invention relates to the further utilisation of such processed biomasses, e.g. for subsequent fermentation into bio-ethanol, bio-gas, specialty carbohydrates for food and fees as well as carbon feedstock for processing into plastics and chemicals.

  • Publication number: 20070016653
    Abstract: Methods, and associated systems and apparatus, relate to controlling one or more target devices with a controller that has an event table that associates simple (non-command formatted) event identifiers with command-formatted commands that can be triggered by network messages containing one of the event identifiers. In some embodiments, event identifiers may be included in the payload of network messages generated in response to a hyperlink command. In an illustrative example, selecting a hyperlink in an application program may cause a simple event identifier, such as event “3”, to be sent in a network message to a controller. In response, the controller may perform operations to execute commands associated with event “3” in the event table. The operations may be performed in the controller and/or transmitted to the target device.

  • Publication number: 20070003602
    Abstract: The present invention provides a process for imparting improved functional properties to a single-cell protein material, said process comprising the step of homogenizing an aqueous slurry of the single-cell protein, e.g, a single-cell protein material derived from fermentation on natural gas. The resulting homogenized protein material has excellent functional properties and finds particular use in the preparation of food products, for example as a gelling agent or emulsifier.

  • Patent number: 4884262
    Abstract: In a stereo pick-up having movable coils (14) and an SmCo magnet (22) with a high energy content, with the coil system (14, 15, 18) arranged in front of one pole face of said magnet, a yoke plate (23) of a magnetic soft material is arranged in front of said system to increase the magnetic induction in the coils. The great coercive force of the magnet is utilized for simplifying and reducing the costs of the mechanical structure in that the yoke plate is formed with two legs (26) which extend rearwardly, engage and are secured to two opposite sides of the magnet. The short-circuit of the magnet established by these legs has no noticeable impact on the induction in the air gap because of the high coercive force of the magnet.
