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 |
