Torrefaction of cellulose, hemicelluloses and lignin extracted from woody and agricultural biomass in TGA-GC/MS: Linking production profiles of volatile species to biomass type and macromolecular composition

The production of volatile species in torrefaction cellulose, hemicellulose and lignin extracted from woody agricultural biomass was quantified as a function temperature. novel coupling TGA to GC/MS through heated storage loop system allowed sampling released at 11 different temperatures single experiment between 200 300 °C, 3 °C.min?1. results showed that the use fractions obtained samples led detection higher number (23) than previous studies with commercial compounds, obtaining degree detail characterization torrefaction. Volatile were generally this study lower those previously reported for compounds. This may be due better preservation properties thanks optimized extraction procedure. profiles assessed based on formation mechanisms proposed literature polysaccharide-based shown correlated their sugar composition. Finally, allow identifying temperature range enhance given
