Estimación de cantidad de carbono fijo almacenado en la madera de dos especies forestales comerciales en la comunidad Amulá Chico, cantón Colta, provincia de Chimborazo.

Abstract

The aim was to obtain the fixed carbon stored in the wood of two commercial forest species in the community of Amulá Chico, Canton Colta, Province of Chimborazo. The research was carried out in two important areas, at the herbarium level and at the laboratory level. At the herbarium level, the methodology established by the Escuela Superior Politécnica de Chimborazo (CHEP) herbarium, was used, where the forest species under study were identified dendrologically: Pinus radiata D. Don and Pinus patula Schiede ex Schltdl. & Cham. In the chemistry laboratory of the Facultad de Recursos Naturales, the methodology of the INEN and ASTM norms for charcoal or coke was used to determine the proximate analysis of wood and/or charcoal, with this analysis the percentages of humidity, volatile material, ash and fixed carbon were obtained, presentating the following results: 57.31% humidity in Pinus patula and 54.86% humidity content in Pinus radiata. In the case of the fixed carbon variable, 7.63% in Pinus radiata wood and 7.39% of fixed carbon in Pinus patula wood. Using these results it was concluded that the humidity variable in the Pinus patula species has a higher content compared to the Pinus radiata species, on the other hand, the Pinus radiata species has a higher content of fixed carbon stored in the wood compared to the Pinus patula species.
