Caracterización físico-química de pellets producidos a partir de mezclas 50/50 carbón bituminoso/madera residual

Biofuels demand characterization and reliable processes to ensure proper manufacturing process for end users in order to use them safely. About 4.42 % of biofuels that are marketed globally are presented as agglomerates or pellets. Considering that Colombia is a country with high coal reserves and, as an agricultural country, produces large amounts of organic waste, our results show that the mixture of these two products has benefits in terms of energy and combustion, facilitating burning and decreasing the emissions of both particulate material and sulfur-containing gases. This article presents the results of the characterization as international pellets produced in the Laboratory for Renewable Energy of the National University of Colombia for 50/50 % mixture of wood and anthracite. The physicochemical parameters evaluation was made using the standard Austrian ONORM M7135, in order to evaluate each of the items established. Also test results and analysis of the characterization of these mixtures and their calorific value according to ASTM D5865 11a and the impact resistance according to ASTM D440-86 are shown. Additionally the advantages and disadvantages are discussed from an environmental point of view related to the use of biofuels agglomerates.
