ABSTRACT
It is known that the
increase in energy density of wood can also be obtained from the production of
briquettes from this biomass residue. Due to the high compaction of these
residues, the briquettes obtained from this have energy density values of two
to three times the value obtained for wood and up to seven times that of the
residue itself. The main objective of this work was to investigate, on an
exploratory basis, the combined effect of pressure and the addition of
carbonaceous solids to the wood structure, on the behavior of the energetic
properties, in particular, the energetic density of this material. Different
wood residues of unknown origin in the form of branches harvested on the UFR
campus were machined with dimensions close to those compacted at different
pressures. The powder residues obtained from turning these branches with a
particle size ≤ 0.85 mm were compacted at pressures of up to 300 MPa. The
machined samples and briquettes produced at different pressures were
characterized via immediate analysis, determination of calorific value and
measurements of bulk density and energy. The results showed that the combined
effect of pressure and the addition of carbonaceous solids to the wood
structure significantly influenced the behavior of the bulk and energetic
densities of this material. Comparing the results, it was possible to identify
in the samples under the aforementioned effect a percentage increase in energy
density of up to 49.4%.
