摘要：
In this study, the physicochemical properties, the thermal degradation behavior and the products generated from pyrolysis of brewer's spent grain (BSG) were investigated to evaluate the potential of this agro-industrial residue for bio-oil production via pyrolysis. Thermogravimetric analyses were performed in a nitrogen atmosphere. The kinetic parameters were estimated by isoconversional methods and by independent parallel reactions model (IPR). The results showed that the BSG has a good potential for bio-oil production owing to its high volatile matter content and the high heating value. The kinetic behavior was successfully modeled by the IPR model. High added-value compounds were identified from analytical pyrolysis, which indicates that BSG can be a source of important raw materials for the chemical industry.
