The humins were obtained by treatment of aqueous solutions of d-glucose and d-fructose at 180 C in the presence of sulphuric acid (0.1 M) and isolated as brown solids in 20-30% yield. The products were characterised with various techniques (SEM, elemental analysis, solid state CP-NMR, FTIR). Pyrolysis GC-MS showed the presence of furanics and organic acids, though the individual components were present in minor amounts (<1 wt%). Micro-pyrolysis yielded 30 wt% gaseous and liquid products, the remainder being a solid char. Gas-liquid yields are lower than obtained for a typical lignin sample (kraft lignin) under similar conditions. © 2013 Elsevier B.V.
