| Resumen | Transcripción del resumen del autor. Hot water pretreatment was systematically studied to determine whether reaction selectivity of cellulose toward the production of anhydrosugars and furanics could be improved. Samples of wheat straw and a-cellulose were treated using hot compressed water at temperatures ranging between 150 and 260 °C. The effect of hot water pretreatment on pyrolysis selectivity was measured using pyrolysis gas chromatography mass spectrometry (Py-GC/MS). Various representative peak area ratios were compared and used as an index of pyrolysis selectivity. The chemical and Py-GC/MS analysis of solid residues resulting from hot water pretreatment suggest that, as the temperature increased, the hemicelluloses and amorphous cellulose were solubilized. The relative areas of the Py-GC/MS results associated with levoglucosan increased for both straw and a-cellulose with increasing treatment temperature. The results show that the selectivity of thermochemical reactions toward the production of sugars and furanics can be enhanced if the material is treated in hot water at temperatures between 220 and 260 °C, and the amount of acetic acid is reduced substantially. Thus, hot water pretreatment may be a viable method to modify the chemical composition of bio-oils produced via fast pyrolysis. |
