摘要:
A digital video recorder employing standard hard disk arrays employs a caching system to enable continuous video data to be supplied to and provided from the standard disk drives which may not be adapted for continuous data stream operation. The system is implemented as an array of disk drives and includes cache management functions for governing disk read and write operations. A predictor enables the cache to predict disk reads and disk writes and to maintain the cache based on the predictions. Redundancy enables playback in the event of failure of a drive in the array and also provides improved playback data retrieval time.
摘要:
A method for the making of a plurality of LCD screens starting with an oversize panel. The panels laid out on the mother glass include a plurality of screen layouts with trace lead-outs around all four sides of a rectangular panel layout. A panel is then made which has conductor traces around the periphery of the panel. The conductor traces may conductor pads on the panel. The panels are then able to be cut into up to four separate final screen panels depending upon the size requirements of the application. Each of the cut final screen panels will have trace contacts along adjacent edges to allow for coupling to flex connectors. As some panels will be left-right images of each other with regard to pixel colors, drivers for the panels will be adapted for RBG to GBR conversion to drive mirror image panels with the same images.
摘要:
A process is described for reducing the oxygen content of a high-oxygen feedstock. The process is particularly suitable for biomass-based feedstocks. The process comprises contacting the feedstock with carbon monoxide and/or coke in the presence of a catalyst. Conveniently, the coke may be present in the form of a deposit on the catalyst. Carbon monoxide may be generated in a regeneration step of the catalyst. The process may be carried out in conventional refinery equipment.

Disclosed is a process for storing solar energy in organic compounds. The process comprises providing a water source and a carbon source. Water present in the water source is activated using solar energy. Activated water is reacted with the carbon source to form an organic compound comprising hydrogen and carbon. The organic compound has higher energy content than the carbon source.In a specific embodiment the organic compound is used as a fuel in an electricity-generating device, such as a fuel cell. In this embodiment the preferred organic compound is methanol.
摘要:
A method for reducing the mechanical strength of solid biomass material, in particular lignocellulosic biomass, comprises mixing the solid biomass material with an inorganic material and heating the solid biomass material mixture to a toasting temperature in the range of 105° C. to 140° C. during an exposure time of from 1 minute to 12 hours. Before or after the heat treatment, which is referred to as “toasting”, the biomass material mixture is subject to flash heating. The treatment significantly reduces the mechanical energy required for reducing the particle size of the solid biomass material and is suitable as a pretreatment prior to a conversion reaction of the solid biomass material.
摘要:
Disclosed is a new composition of matter comprising a polymeric material of photosynthetic origin having embedded therein small particles of an inorganic material. The composition of matter is particularly suitable for use in processes whereby the polymeric material is converted to fuels in liquid or gas form, and/or to the valuable specialty chemicals. The polymeric material comprises biomass. More specifically, the polymeric material comprises cellulose and at least one of hemicellulose and lignin.
摘要:
A process is disclosed for converting a particulate solid biomass material to a high quality bio-oil in high yield. The process comprises a pretreatment step and a pyrolysis step. The pretreatment comprises a step of at least partially demineralizing the solid biomass, and improving the accessibility of the solid biomass by opening the texture of the particles of the solid biomass. In a preferred embodiment the liquid pyrolysis product is separated into the bio-oil and an aqueous phase, and the aqueous phase is used as a solvent in the demineralization step and/or in the step of improving the accessibility of the solid biomass by opening the texture of the particles of the solid biomass.
摘要:
A method for converting solid biomass into hydrocarbons includes contacting the solid biomass with a catalyst in a first riser operated at a temperature in the range of from about 50° C. to about 200° C. to thereby produce a first biomass-catalyst mixture and a first product comprising hydrocarbons; a) separating the first product from the first biomass-catalyst mixture; c) charging the first biomass-catalyst mixture to a second riser operated at a temperature in the range of from about 200° C. to about 400° C. to thereby produce a second biomass-catalyst mixture and a second product comprising hydrocarbons; d) separating the second product from the second biomass-catalyst mixture; e) charging the second biomass-catalyst mixture to a third riser operated at a temperature greater than about 450° C. to thereby produce a spent catalyst and a third product comprising hydrocarbons; and f) separating the third effluent from the spent catalyst.
摘要:
A process is disclosed for pretreating lignocellulosic biomass. The process comprises swelling the lignocellulosic biomass with an aqueous liquid. The pretreated lignocellulosic biomass may be used as a feedstock for the enzymatic conversion to ethanol, or in a thermal conversion process to produce bio-oil. The pretreatment results in a greater yield and, in the case of a thermal conversion process, a better quality of the bio-oil.The pretreatment process may be used to adjust the composition and amount of inorganic material present in the lignocellulosic biomass material.
摘要:
A modular biomass treatment unit includes a first module having a pretreater and a first frame for transportation to and operation at a site adjacent to a solid biomass growth source. The pretreater is operable to process solid biomass to produce a plurality of solid biomass particles for conversion into a fuel or specialty chemical. The first frame supports the pretreater during transportation to and operation at the site adjacent to the solid biomass growth source. The modular biomass treatment unit can also include additional modules each comprising a reactor, a separator, and a frame for transportation to and operation at a site such as the site adjacent to the solid biomass growth source.
