Estudio térmico e infrarrojo de cinco tipos de madera comercializadas en Norte de Santander en tres etapas diferentes del proceso secado, para su posible uso como fuente de energía.

Abstract

In this work, we determined the thermal properties of five types of wood sold in Norte de Santander, Colombia: cedar (Cedrela Montana), pine (Cupressus lusitánica mil), eucalyptus (Eucalyptus globulos labill), guadua (Guadua angustifolia) and pardillo (XXX). The analysis was made on three drying stages (fresh, intermediate and dry), using combustion calorimetry and simultaneous thermogravimetric analysis (TGA) / differential scanning calorimetry (DSC). The results showed the presence two loss of weight and three thermal events (2 endothermic and 1 exothermic), this events are due to the moisture and the degradation of chemical composition of the samples. Additionally, we analyzed the different samples using Fourier transform Infrared spectroscopy (FTIR) that showed the presence of cellulose, lignin, hemicellulose, aliphatic and aromatic hydrocarbons, alcohols, phenols, aldehydes, ketones and aliphatic acids.
