Ash Free Pyrolysis Liquidl from Softwood Forestry Residue

K. Toven, J. Celaya, M. Lenes & A.V. Bridgwater
In Scandinavia, the wood processing industry leaves large amounts of forest residue that could be used for producing a renewable liquid fuel through fast pyrolysis. A bottleneck for pyrolysis liquids produced from ash¬containing feedstock is that the presence of solids (char, ash) in pyrolysis liquids makes the pyrolysis liquid unsuitable for direct combustion in conventional boilers and turbine operations due to problems with fouling, corrosion, erosion and plugging. The aim of this study is to...
