 Abstract

The potential contribution of bioenergy in the global energy system is 17 – 36% of primary energy consumption. To avoid a warming higher than 2 Â °C by 2050, it is estimated that biomass should provide 60% of total renewable energy consumption. This requires amplification in efficient alternatives of energy production from renewable sources. In Mexico there is a great potential of biomass resources to produce biofuels, in which the wood is 54% with low contribution of forest plantations. The need to give greater value to forest plantations with native species is urgent in elaborating prospects for bioenergy development. In this sense, was determined the production and quality of charcoal of five native species of Tamaulipan thorn scrub, Acacia berlandieri, Havardia pallens, Helietta parvifolia, Ebenopsis ebano and Acacia wrightii. Analyzes conducted to define the quality of charcoal sampled referred to their yield, percentages of moisture content, ash, volatile material and fixed carbon of each species, based on international standards. It was found that the yield of charcoal was from 20 to 30%, corresponding to branches of A. berlandieri and trunk of A. wrightii, respectively. The percentages of moisture content, volatile material, ash and fixed carbon presented ranges of 4.25 to 4.9%, 12.29 to 22.28%, 1.68 to 6.49% and 68.26 to 81.34%. The average calorific value was 30 000 kJ kg-1, consistent with the requirement for use for energy purposes.
