dc.description.abstractThe demand for new energy sources is growing and awakening interest in the use of forest residues. Charcoal was prepared at carbonization temperatures of 500 ºC, 600 °C and 700 °C in order to evaluate the potential use of Pinus sp needles for energy. The anatomical and chemical characteristics of the needles and the charcoal produced were also evaluated. The needles were found to have ash content of 2.32% and gross calorific value of 20.30 MJ/kg. The calorific value increased by 45%, reaching 29.64 MJ/kg, after carbonization carried out at 600 ºC. This value is higher than that for charcoal made from eucalyptus (19.25 MJ/ kg) and even coconut husks (23.55 MJ/kg), showing the high energy potential of these needles. 
dc.description.resumoA crescente demanda por novas fontes de energia vem aumentando o interesse em pesquisas para a utilização de resíduos florestais. Foram preparados carvões a temperaturas de 500 ºC, 600 °C e 700 °C com o objetivo de avaliar o potencial de uso de acículas de Pinus spp. para energia. Foram avaliadas as características anatômicas e químicas das acículas e do carvão produzido. O conteúdo de cinzas das acículas foi de 2,32% e o poder calorífico de 20,30 MJ/kg. O poder calorífico aumentou 45%, alcançando 29,64MJ/kg após a carbonização em temperatura de 600 ºC. Esse valor é superior ao carvão feito de eucalipto (19,25 MJ/kg) e coco (23,55 MJ/kg), mostrando o bom potencial de uso para energia.
