CANTOS-MACIAS, Manuel Angel et al. Kinetic of ecuadorian wood residues pyrolysis. Rev Cub Quim [online]. 2018, vol.30, n.3, pp. 400-422. ISSN 2224-5421.

The use of food as a source of energy has been questioned and agroforestry waste shows potential for these purposes. The objective of the work is to realize the chemical and energetic characterization of waste from Ecuador and study the kinetics of its pyrolysis, as an alternative for its use. Elemental, immediate analysis was carried out and thermal analysis techniques were applied. The higher carbon content and lower humidity and ash of Teak, favor its energétic use, with respect to Fernán Sánchez. In addition, its nitrogen and sulfur contents below 1 %, guarantee low NO_x and SO₂ emissions, reducing its environmental impact. The combined use of TGA, DTG and DSC allows to identify the three stages of pyrolytic cracking, the decomposition of hemicellulose, cellulose and lignin. His kinetic study showed that the first and third stages are determined by diffusive processes fundamentally and in the second, different kinetic models prevail.
