Resumen:
Detailed studies about energy content and chemical characterization of
biomass alternatives are necessary to determine their main features as
solid fuels. The aim of this study was to analyze and compare the
properties of five types of residual biomass pellets produced throughout
Mexico: sawmill pine waste (SPW), spent ground coffee (SGC), pecan
nutshell (PN), oil palm waste (OPW), and mango waste (MW). Conventional
characterization analyses revealed significant differences in HHV
(21.44-17.37 MJ/kg), elemental composition showed a lower carbon content
in SPW and MW (around 46%), OPW (close to 47%), and higher carbon
content in PN and SGC (around 51%). The concentration of the main
structural polymers showed notable significant differences (p < 0.05)
too: 49-17% for cellulose, for hemicellulose 21-5% and for lignin
26-4%. High-throughput instrumental techniques were also used: FTIR
provided additional information on chemical composition in pellets on
which lignocellulosic biomass was not predominant, presence of pectins
and starch in MW, and high content of fatty acids in SGC and OPW; TGA
showed different thermal stability of pellets in the combustion process,
where OPW and SPW presented the lowest and highest thermal stability,
respectively, while XPS showed different types of bonds between C and O
in the surface of materials with a relevant presence of bonds associated
to lignin covering PN and SPW. Based on results of this investigation, a
possible rank for the energy use of these five biomasses is suggested:
PN, SPW, SGC, OPW, and MW, but future deep research is necessary that
incorporate other relevant attributes, mechanical properties, emission
profiles, corrosion, and slagging effects.
