The presence of ash, ranging from 0.26 wt.% for spruce to 3.76 wt.% for wheat straw (moisture free basis) favoured decomposition of cell-wall constituents to char (spruce [11.4 wt.%] < Salix [16.2 wt.%] < Miscanthus [21.8 wt.%] < wheat straw [21.5 wt.%]) with a reduction of liquid organic product (spruce [53.8 wt.%] > Salix [45.4 wt.%] > Miscanthus [37.3 wt.%] > wheat straw [37.2 wt.%]). Bio-oils from Miscanthus and wheat straw were inhomogeneous. Differences between absolute masses of compounds determined by GC/MS-FID of the bio-oils compared with Py-GC/MS-FID suggested a greater role of secondary reactions at the fluidised bed scale, with reduced concentrations of certain lignin-derived, furan and pyran compounds.||Funding Details:||Science Foundation Ireland||Type of material:||Journal Article||Publisher:||Elsevier||Journal:||Journal of Analytical and Applied Pyrolysis||Volume:||103||Issue:||September 2013||Start page:||96||End page:||101||Copyright (published version):||2012 Elsevier||Keywords:||Fluidised bed; Biomass; Pyrolysis; Biofuel; Secondary reactions; Ash||DOI:||10.1016/j.jaap.2012.10.017||Language:||en||Status of Item:||Peer reviewed|
