| dc.description.abstract | El bagazo de la palma africana es un material lignocelulósico, obtenido en las plantas de tratamiento de aceite como subproducto de desecho, representando aproximadamente el 45% del total de la palma africana procesada. El uso y aplicación de estos materiales ha mantenido la atención de las autoridades ambientales y al sector privado empresarial ya que en los últimos años se han incrementado las exportaciones de palma africana, siendo los cultivos colombianos los primeros en Latinoamérica. Sin embargo de esta agroindustria solo se aprovecha alrededor del 10% quedando una gran cantidad de residuos, que van en aumento. Debido a la forma de procesar la palma, estos desechos causan un impacto ambiental negativo considerable en las regiones, ya que el bagazo no se utiliza directamente como abono orgánico, por que debe pretratarse para un compost. En este trabajo, se estudió la preparación de carbones activados empleando como precursor residuos fibrosos de la industria aceitera (ráquis de palma africana), mediante activación “física” en dos etapas usando dióxido de carbono, y vapor de agua como agentes activantes a diferentes temperaturas (89 – 400°C) y variando los tiempos de activación (hasta 240 min.). El acondicionamiento de las muestras se hizo mediante astillado, molido, tamizado y secado al aire, con el fin de unificar su contenido de humedad, y el tamaño de partícula en un diámetro que vario entre 1mm y 2 mm. | |
| dc.description.abstractenglish | The African palm tree stalk is a ligniferous cellulose material, obtained in oil treatments plants as waste sub-product; such stalk represents approximately 45% of the processed palm tree. The use and application of those materials has kept the attention of environmental authorities and private business field for the reason that, in the last few years, importation of African palm tree has augmented, reaching one of the top places in Latin-American market. Nevertheless, only an insufficient 10 % from the total industry is being profitable, and the residual wastes from the processing increases. Those residual wastes from the palm tree processing cause a considerably negative environmental impact in the nearby regions due to the fact that the stalk is not properly used as organic manure because such stalk must be pre treated for compost. In the following paper, the preparation of activated carbons was studied, using fibrous residual waste from oil industry as precursor (African palm tree stalk). This process was performed through physical activation in two stages: employing carbon dioxide and water vapor as activating agents at different temperatures (89 – 400 Celsius degrees) , and varying activation times ( up to 240 minutes). The sample conditioning was carried out by means of chipping, grinding, sifting and air drying, so that it would be possible to unify its moisture content and particle size to a diameter that oscillated between 1 and 2 millimeters | |
