Chemical composition and thermal properties of tropical wood from the Yucatán dry forests

Six different species of dry forest trees were collected, and their chemical compositions and thermal properties were determined. Three of the six species (Senegalia gaumeri, Havardia albicans, and Lysiloma latisiliquum) were chosen due to their high preference as firewood in local communities, whil...

Descrição
Resumo:Six different species of dry forest trees were collected, and their chemical compositions and thermal properties were determined. Three of the six species (Senegalia gaumeri, Havardia albicans, and Lysiloma latisiliquum) were chosen due to their high preference as firewood in local communities, while the remaining three species (Croton glabellus, Lonchocarpus yucatanensis, and Neomillspaughia emarginata) were chosen because of their abundance at the sampling site. The chemical compositions were consistent with the composition of tropical woods reported in previous literature, with an ash content of 4.8% to 6.8% and total extractible content in the range of 15.4% to 28.5%. The lignin content was in the range of 17.6% to 24.0%, while the range of holocellulose was 53.9% to 63.0%. The calculation of the calorific values was performed using the elemental analyses, and values ranging between 16.2 and 18.5 MJ/kg were obtained. The fuel value index (FVI) values for the samples indicated that S. gaumeri and L. yucatanensis were the best species for fuelwood given their high densities and relatively high calorific values. The kinetics of pyrolysis showed a higher level of reactivity for H. albicans and L. yucatanensis compared to the other species studied.
