Beschreibung
Technischer Bericht aus dem Jahr 2018 im Fachbereich Energiewissenschaften, , Veranstaltung: Erneuerbare Treibstoffe, Sprache: Deutsch, Abstract: Wood Pellets are well known and a part of the global trading. But the main problems are the high costs, the energy needed, the high quality of wood, leads to a product, without any industrial application. For industrial application we need larger pellets up to 25 mm diameter and higher, with a very low ash production, with low limits in pollution like metals and organic compounds. Those industrial pellets can substitute fossil coal, and fossil crude oil. Beside the application of industrial pellets we are now in the position to recycle municipal waste and to produce pellets as secondary fuel or pellets as refused fuel. The classical pellets can be used in combustion chambers with attached boilers, this technology is well known. The industrial pellets can be used in gasifiers to produce a weak gas and charcoal. secondary fuel and RDF pellets can be used in advanced gasifiers to generate weak gas and charcoal. Again we have to recycle and separate the wood and waste wood and municipal waste into metals, plastics and biogenic waste. The biogenic waste has to be separated into used natural wood, used coated wood, in biogenic waste and in biogenic waste with plastic foils. Metals and plastics will be recycled in the industrial processes. With the separation and recycling process we now in the position to qualify the wood waste and to generate weak gas and charcoal or to generate a strong syngas for dimethyl ether production.
