摘要: This research details the characterisation of four Irish-grown lignocellulosic biomasses for pyrolysis by biomass composition analysis, TGA, and Py-GC/MS-FID. Ash content (mf) increased in order spruce (0.26 wt.%) < salix (1.16 miscanthus (3.43 wheat straw (3.76 wt.%). Analysis hydrolysis-derived sugar monomers showed that xylose concentrations (4.69–26.76 ranged significantly compared to glucose (40.98–49.82 Higher hemicellulose ash contents probably non-volatile matter, decreased temperature maximum degradation TGA as well yields GC-detectable compounds Differences were reflected pyrolysate lower quantities sugars (principally levoglucosan), pyrans, furans salix, miscanthus, spruce, cyclopentenones acids.
