Abstract
Description
Verfahren zum Aufarbeiten von Process for processing
zellulosehaltigen Biomassen bzw. cellulosic biomass or
Braunkohle und Lignit zu einem einheitlichen, stark reaktionsfähigen, staubförmigen Brennstoff. Brown coal and lignite to form a uniform, highly reactive, powdery fuel.
Die im folgenden beschriebene Erfindung hat zum Ziel.fossile geologisch jüngere Biomassen wie Torf, Braunkohle, Lignit etc., insbesondere aber nachwachsende, zellulosehaltige Biomassen wie Elefantengras, Strohs, Bagasse, Holz etc. zu einem einheitlichen staubförmigen stark reaktionsätign Brennstoff aufzuarbeiten.The invention described below aims to geologically fossil fuels younger biomasses such as peat, lignite, lignite etc., but especially renewable, cellulosic biomass such as elephant grass, straw, bagasse, wood etc. in one Working up uniform, powdery, highly reactive fuel.
Die oben genannten Materialien fallen in--vielfältigen Formen an. Hier ist einer der Gründe, weshalb sie bis heute als Energieträger kaum beachtet werden. Auch ihr Heizwert ist durch den hohen Gehalt von Ballaststoffen wie Feuchte, Sauerstoff etc. sehr gering.The above-mentioned materials come in a variety of forms. Here is one of the reasons why it is still neglected as an energy source to this day will. Their calorific value is also due to the high content of dietary fibers such as moisture, Oxygen etc. very little.
Bertinisieren ist ein altes Verfahren, was zur Kohleveredelung entwickelt wurde, aber nie praktische Bedeutung erlangte. Bei diesem Bertinisieren wird das Material unter Luftabschluß auf eine Temperatur von 250 bis 3000 C erhitzt, wobei zuerst die Feuchte dampfförmig ausgetrieben wird.Bertinizing is an old process that developed for coal refinement but never achieved practical importance. With this Bertinization that becomes Material heated to a temperature of 250 to 3000 C with the exclusion of air, wherein first the moisture is expelled in vapor form.
Im weiteren wird ein wesentlicher Teil des Sauerstoffes inform von Konstitutionswasser und Kohlensäure und wenn vorhanden, ein großer Teil des Schwefels als Schwefelwasserstoff und andere gasförmige Ballaststoffe abgeschieden.In the further a substantial part of the oxygen becomes inform of Constitutional water and carbonic acid and, if available, a large part of the sulfur deposited as hydrogen sulfide and other gaseous fiber.
Lufttrockenes Material mit ca. 15 % Restfeuchte verliert beim Bertinisieren fast die Hälfte seines Gewichtes.Air-dry material with approx. 15% residual moisture loses when bertinizing almost half of his weight.
Sein Heizwert steigt dafür im Mittel auf ca. 7000Kcal/Kg an. Bei der Bertinisierung von zellulosehaltigen Biomassen darf die Erhitzung nur bis kurz unterhalb der Temperatur kommen, bei welcher ihre Meilervorgänge anspringen un-d exotherm, selbstgehend weiter verlaufen.Its calorific value increases on average to approx. 7000Kcal / kg. In the Bertinization of cellulosic biomass may only be heated to just below come to the temperature at which their kiln processes start and are exothermic, continue to run independently.
Bei der anschließenden Mahlung wird eine Gleichförmigkeit aller Stoffe und bei Verbrennung eine hohe Energieausbeute erreicht. In manchen Entwicklungsländern wäre eine Mahlung mit viel Überkorn angebracht,çm aus dem Überkorn nach Absiebung eine Art Kunstbrennstoff (Brikett oder Preßlinge) herzustellen. In diesen Ländern ist meist ein großer Mangel an Primitivbrennstoffen.During the subsequent grinding process, all materials become uniform and achieves a high energy yield when burned. In some developing countries Milling with a lot of oversized grain would be appropriate, çm from the oversized grain after sieving to produce a kind of synthetic fuel (briquette or pellets). In these countries is usually a great lack of primitive fuels.
Durch die Bertinisierung und Mahlung wird eine starke Aufspaltung der Makromoleküle erreicht. Hierdurch ist eine Unzahl von ungesättigten Bindungen entstanden, welche die Sorption mit Luftsauerstoff aber auch Luftfeuchte geradezu herausfordert. Das eine bedingt erhöhte Explasionsgefahr und zusammen eine Minderung des Heizwertes. Aus diesem Grunde muß auch die Mahlung, Lagerung und der Transport unter Luftabschluß, also sauerstoffrei und trocken stattfinden.Through the Bertinization and grinding there is a strong splitting of macromolecules. This creates a myriad of unsaturated bonds originated, which the sorption with atmospheric oxygen but also air humidity downright challenges. That is a conditionally increased risk of explosion and together a reduction the calorific value. For this reason, the grinding, storage and transport take place in the absence of air, i.e. oxygen-free and dry.
