| Summary: | [Display omitted]
•Brewer's spent grain (BSG) was evaluated for its potential to produce biofuels.•A chemical characterization was performed considering a pyrolysis process.•A kinetic study of the pyrolysis process was performed.•Important chemicals were identified from pyrolysis products.
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. |
