Kraft Lignin as an Additive in Pine and Eucalyptus Particle Composition for Briquette Production

Abstract: The objective of this study was to evaluate the properties of briquettes produced with different proportions of pine and eucalyptus wood, as well as to characterize the potential of kraft lignin as an additive in the composition of briquettes for energy generation. The treatments differed from one another in the pine and eucalyptus wood particle ratios (0, 25, 50, 75 and 100%), as well as for the kraft lignin content (0, 2, 4, 6, 8, 10, and 12%). The biomasses were characterized by their physical and chemical … Show more

“…Regarding to the kraft lignin composition, it is possible to verify that the studied lignin in this research has similar percentage of carbon (49.8% -61.8%), hydrogen (5.0% -6.5%), nitrogen (0.1% -1.3%), but lower oxygen content (29.2% -37.9%) and significantly higher content of sulfur (0.8% -2.5%) [29] [85] [86] [87]. This information and the higher ash content directly influence in the lignin purity and energy generation.…”

“…The purity is also related to the acid insoluble (Klason lignin) and soluble lignin presented in the binder material. Compared to Zhou and Lu [86] and Boschetti et al [29] the studied kraft lignin used in this research is more impure, presenting lower contents of total lignin on its composition. However, the carbohydrates content presented is lower than other studies [85] [86] [87].…”

“…Lignin is reported to be used as a binder in briquette application [ 1 , 2 , 19 , 20 , 21 , 22 ]. Previous research studies utilized lignin as a binder for anthracite-based briquette [ 23 ], organic municipal solid waste [ 24 ], and wood [ 4 , 25 ]. It was also reported that lignin can serve both as a binder and fuel, improving both the physical and heat properties of the briquette.…”
