Chemical Characterization of Eucalyptus sp. Residues from Short- Rotation Forests for Bioenergy Production

Abstract: Abstract:The use of biomass resources to generate energy has been growing as renewable alternative, foremost because of their promising properties. Nowadays, one of the newest alternative resources under study is the biomass from shortrotation forests. However, such process lacks development to be used in commercial scale in Brazil, despite its positive perspectives. The aim of the present study is to chemically characterize Eucalyptus sp. residues, in order to find their potential applicability as sustainable… Show more

“…100B presented the lowest value, at 66.16%. The contents obtained for 100T and 90T10B are in accordance with the literature [55,56,[58][59][60] for residues of different biomass, such as Eucalyptus sp. sawdust, Pinus sp.…”

“…In this research, the logs for thinned logs and log tops had higher percentages, followed by trimmings, edgings, deteriorated logs, and crowns. All averages of the biomass cited were similar to those found for teak 5 and 8 years old (Silva et al 2015) and were in line with those described in the study by Teixeira et al (2016) when evaluating Eucalyptus sp. It is possible to verify that the slabs presented lower VM and differed statistically from the group with a higher mean.…”

“…Para o uso energético, deve-se destacar o teor de lignina total e o teor de cinzas. O primeiro está diretamente ligado ao potencial energético da biomassa, já que é um componente rico em carbono e hidrogênio (Teixeira et al, 2016), e seu poder calorífico é superior ao da celulose, o que indica que espécies com elevados teores de lignina apresentam melhor desempenho energético (Couto, 2004). O segundo componente, além de contribuir negativamente para o aproveitamento energético, influencia a operação e a limpeza da caldeira, pois, biocombustíveis com maior teor de cinzas impõem condições abrasivas e podem fundir a elevadas temperaturas ao aderir aos elementos metálicos, o que é indicativo da necessidade de uma remoção mais eficiente e regular das cinzas (Carneiro, 2013;Liu et al, 2014).…”
