Abstract:
A method and apparatus for producing sheets from the pseudostems of banana plants in the family Musaceae, each pseudostem having a longitudinal axis. The method includes the steps of feeding a pseudostem (14) into a workstation, supporting (62, 34) the pseudostem for rotation thereof about its longitudinal axis within the workstation, and contacting the rotating pseudostem along substantially its entire length with a fibre-separating device (38), whereby a continuous sheet of fibre (60) is removed from the pseudostem by the fibre-separating device during rotation. Raw paper may also be made by laminating two or more of these sheets together such that the direction of the generally parallel fibres in at least two adjacent sheets is not aligned and then curing the sheets to form raw paper.
Abstract:
The present invention relates to a method for pre-treating biomasses, more particularly for pre-treating biomasses intended for a biorefinery or similar facility for producing biofuels. The method for pre-treating biomasses according to the invention comprises a shredding step (40) and, upstream of said shredding step, a soaking step (30), in particular by immersion in corresponding soaking vessels, and simultaneous removal of foreign bodies from said biomasses (30'). The present invention further relates to a plant for pre-treating biomasses (100) capable of implementing the above-described method and comprising to this aim a shredding station (140) for shredding the biomasses and, upstream of said shredding station, a soaking station (130), in particular comprising one or more soaking vessels (132).
Abstract:
The present invention relates to a soaking vessel for soaking biomasses, more particularly for soaking biomasses intended for a biorefinery or similar facility for producing biofuels. Thanks to the provision of specific measures for advancing the biomasses through the basin and a specific extracting device (11) for extracting them from said basin, the soaking vessel (1) according to the invention allows to soak high flow rates, in the range of 20 - 50 t/h, of biomasses and extract them for transferring them to the subsequent processing steps. In a preferred embodiment of the invention, the soaking vessel (1) is further provided with means for removing foreign bodies (15, 17, 19), whereby simultaneously with soaking of the biomass a removal of foreign bodies that are initially contained inside said biomass and separate therefrom during its advance movement through the soaking vessel (1) can be effected.
Abstract:
A process for producing polyols from a low viscosity slurry comprising a thermally treated ligno-cellulosic biomass which has been subjected to a fiber shives reduction step is provided. Specifically, a continuous process for catalyzing the formation of polyol products, such as ethylene glycol and propylene glycol, from the low viscosity slurry is provided.
Abstract:
Die Biomasse wird mindestens einem Zerkleinerungsschritt unterworfen, der mittels eines Wasserschneiders erfolgt. Die Schneidflüssigkeit kann außer Frisch- und/oder Brauchwasser eine mit Substraten beaufschlagte, gärfördernde, chemische Elemente auswaschende, gegebenenfalls auch bindende, gegebenenfalls temperierte Prozessflüssigkeit, gegebenenfalls auch Gülle sein. Sie kann im Kreislauf geführt werden. Das Verfahren und die Vorrichtung werden durch eine dosierte Zuführung der Biomasse zum Wasserschneider bestimmt. Die anschließende Weiterverarbeitung kann einen Waschvorgang oder eine mechanische Abscheidung von Flüssigkeit beinhalten.
Abstract:
Examples to process print media (105) are defined herein. At least one marked cell from a plurality of cells (305) extending throughout a processed image of the print media (105) is detected. The processed image of the print media (105) may include marked portions (110) and unmarked portions (115). Further, the marked cell overlays a marked portion of the processed image. Once the marked cell is detected, the marked portions (110) of the print media (105) corresponding to the marked portions (110) of the processed image may be determined and separated from the print media (105) to provide a processed media (130) comprising the unmarked portions (115).

Abstract:
In order for a method for preparing fibres for producing paper from a fibre-containing material, in particular from waste paper, to be improved such that shortening of the fibres separated from the fibre material is reduced to a minimum, it is proposed that the fibre-containing material is supplied in a moist state for pulping and is pulped to a dry state by continuous impact action.
Abstract:
A composite board is manufactured from hydrophobic coconut coir fibers which have been treated to remove at least a portion of coconut pith therefrom; and a hydrophobic vinyl polymer, such as a polyolefin. The composite board is manufactured without any step of chemically modifying coconut coir fibers. The composite board is manufactured by removing at least a portion of coconut pith from coconut coir fibers using a cyclonic separator; combining coconut coir fibers with a hydrophobic polymer to form a mixture; and extruding the mixture to form a composite board.
