ScienceDaily (Apr. 16, 2012) — Forest residues such as stumps, bark and twigs are now proving of great benefit in a new test facility for the production of high-quality synthesis gas intended for transport fuels. The results which are unique in Scandinavia, are based on close cooperation between Luleå University of Technology, the Energy Technology Centre (ETC) and industry.
By applying known gasification technology, valuable synthesis gas has been obtained from waste materials from the forest.
“We chose to take the shortest route and make use of, for example, tree stumps and the tops of trees from the forest and use them as they are in our facility.Primarily, we use make use of low-quality forest residues which the wood and paper industry cannot use.People often talk of the need to pre-treat these kinds of raw materials or to use it with charcoal to produce synthesis gas effectively.What we have done is to show how to use forest residues directly — and this is an important aspect of our success,” says CEO Magnus Marklund, at ETC in Piteå.
