| 英文摘要 | To systematically examine the effects of anaerobic digestion (AD) pretreatment on product distribution and kinetics of distillers' grains (DG) and its digestates collected at different AD durations, Py-GC/MS and TG ana-lyses were conducted. Py-GC/MS analysis revealed a reduction in the proportion of oxygenated and nitrogenous compounds in all digestates and increase the share of hydrocarbons: 46.72% (SD-2), 65.53% (SD-4), 43.20% (SD -6) and 50.05% (SD-8) than DG (38.61%). To assess activation energy, Friedman, Kissinger-Akahira-Sunose and Flynn-Wall-Ozawa models were employed with average values ranging from 159.54 to 170.96 kJ mol-1 for DG, 156.59-165.42 kJ mol-1 for SD-2, 15.67-166.47 kJ mol-1 for SD-4, 153.28-159-45 kJ mol-1 for SD-6, and 156.02-167.37 kJ mol-1 for SD-8, which were lowered than DG. Thermodynamic studies showed positive Delta H and Delta G values, suggesting that the pyrolysis of DG and digestates is non-spontaneous. The negative Delta S values implied that the degree of disorder in products resulting from bond dissociation was lower than initial reactants. These findings provide valuable insight into the potential of AD as a pretreatment method and offer an under-standing of the pyrolysis behavior of digestates. This study not only offers practical guidance but also contributes to the theoretical framework for utilizing AD as a pretreatment method for pyrolysis. |
