Resumen: | El presente trabajo consiste en aprovechar las hojas de palma de aceite provenientes del cultivo Camelios de Esperanza ubicado en el municipio de Granada en el departamento del Meta (Colombia) para la obtención de matrices carbonadas vegetales activadas (MACAVEA). Para ello se llevó a cabo una matriz de selección basada en el método de Monte Carlo con la que se eligió el tratamiento termoquímico de pirolisis lenta para ser aplicado a las hojas de palma de aceite, posterior a ello se realizó un diseño experimental 22 variando la temperatura y tiempo de residencia para analizar la influencia de ambas variables en el rendimiento de la carbonilla, con lo cual se comprobó que la temperatura es el factor que presenta mayor influencia en el proceso pirolítico, donde el mayor rendimiento del carbón fue del 35,86% en las condiciones de operación de 550°C y 4 horas. Posterior a su obtención, el carbón fue activado químicamente a partir de H3PO4 al 85% a 450°C y 15 horas para ser sometido a pruebas de adsorción de yodo y azul de metileno en soluciones acuosas, donde se estimó la presencia de microporos y mesoporos a través de la adsorción de moléculas de pequeño y gran tamaño. |
Abstract: | The present work consists of taking advantage of palm leaves of oil from the Camelios de Esperanza crop located in the municipality of Granada in the department of Meta (Colombia) to obtain activated vegetable carbon matrices (MACAVEA). For this, a selection matrix based on the Monte Carlo method was chosen, with which the thermochemical treatment of slow pyrolysis was chosen to be applied to oil palm leaves, after which an experimental design 22 was made, varying the temperature and time of residence to analyze the influence of both variables on the performance of the char, which was found that temperature is the factor that has greater influence on the pyrolytic process, where the highest yield of coal was 35.86 % in operating conditions of 550 ° C and 4 hours. After obtaining it, the coal was chemically activated from 85% H3PO4 at 450 ° C and 15 hours to be subjected to iodine and methylene blue adsorption tests in aqueous solutions, where the presence of micropores and mesopores was estimated. |
