Abstract
Die Vergasung erfolgt im Druckbereich von 5 bis 150 bar mit Sauerstoff, Wasserdampf und/oder Kohlendioxid als Vergasungsmittel, wobei die Pellets im Reaktor auf ein Festbett gegeben werden, das sich langsam nach unten be wegt, in das man die Vergasungsmittel von unten einleitet und unter dem die mineralischen Bestandteile als feste Asche oder flüssige Schlacke abgezogen werden. Zum Her stellen der Pellets erzeugt man zunächst eine Mischung, deren Anteil an feinkörniger Hartbraunkohle mindestens 80 Gew.-% beträgt, wobei die Hartbraunkohle eine Kör nung von höchstens 1 mm aufweist. Die zu pelletierende Mischung besitzt einen Wasser- und Feuchtegehalt von 10 bis 25 Gew.-% und einen Gehalt an Betonit von 4 bis 10 Gew.-%. Aus der Mischung formt man unter Zugabe von Wasser als Pelletierflüssigkeit feuchte Pellets, die einen Wasser- und Feuchtegehalt von 25 bis 35 Gew.-% aufwei sen. Die feuchten Pellets werden in einer wasserdampfrei chen Atmosphäre getrocknet, dabei wird der Kern der Pel lets auf mindestens 90 °C aufgeheizt, bevor die Pellets ein Zehntel oder mehr ihres Wassergehaltes verlieren. Die ge trockneten Pellets weisen einen Wasser- und Feuchtegehalt von hcöhstens 4 Gew.-% auf. Die feuchten Pellets können z.B. in einem Sandbett getrocknet werden. Gasification takes place in the pressure range from 5 to 150 bar with oxygen, water vapor and / or carbon dioxide as Gasifying agent, the pellets in the reactor to one Fixed bed are given, which is slowly down into which the gasifying agents are introduced from below and under which the mineral components as solid Ash or liquid slag are removed. To Her the pellets are first made into a mixture, their share of fine-grained hard lignite at least Is 80 wt .-%, the hard lignite a Kör a maximum of 1 mm. The one to be pelletized Mixture has a water and moisture content of 10 up to 25% by weight and a concreteite content of 4 to 10% by weight. The mixture is formed with the addition of Water as a pelletizing liquid moist pellets, one Water and moisture content from 25 to 35% by weight sen. The moist pellets are steam free Chen atmosphere dried, thereby the core of the Pel lets be heated to at least 90 ° C before the pellets enter Lose tenths or more of their water content. The ge Dried pellets have a water and moisture content from at most 4% by weight. The moist pellets can e.g. be dried in a sand bed.
