dc.description.abstractIn this study, a novel method of hydrothermal electrolysis of microcrystalline cellulose (MCC) under sub-critical water conditions (200 degrees C) was investigated by applying direct current at constant voltage with the presence of acid catalyst of 5mMH(2)SO(4). Direct current at constant voltage of 2.5V, 4.0V and 8.0V was applied between cylindrical anode (titanium) and cathode (reactor wall). Hydrothermal electrolysis reactions were carried out in a batch reactor (450mL-T316) for the reaction time of 240min. Decomposition products of MCC were analyzed by GC-MS and the decomposition pathway of cellulose under applied voltage was postulated. Levoglucosan and levoglucosenone formations were detected as the first hydrolysis products of MCC and further hydrolysis yielded to formation of glucose and fructose. The major decomposition products of cellulose were detected as levulinic acid (LA), 5-HMF and furfural. Further reactions of LA such as electrochemical decarboxylation, dehydration, hydrogenation, resulted in the formation of 2-butanone, 2-butanone-3-hydroxy, gamma-valerolactone, respectively. Most dramatic results on the product distribution were obtained at applied 2.5V voltage in which LVA and 5-HMF were selectively produced. [GRAPHICS] .en_US
