Resumo: | Brazil has a privileged position as a leader in the integral use of vegetable biomass because it has the largest biodiversity on the planet. Adding value to a refinery is associated with the treatment and disaggregation of the biomass components. There are processes applied to biomass fractionation to remove or break the layers of lignin and hemicellulose, which allows enzymes to access cellulose more easily. In view of this a great diversity of technological routes can be used, and alternative techniques that have been developed such as the use of the natural deep eutectic solvent (NADES). Thus, the objective of the present work was to perform the fractionation of the bark biomass from E. urograndis species into two fractions: cellulose rich fraction (CRF) and lignin rich fraction (LRF) using NADES. In this process three conditions were applied for biomass fractionation: conventional heating at 100ºC, microwave radiation with power of 600W and 1000 W, and room temperature at 25ºC. The percentages obtained through conventional heating were 72,25% of CRF, 27,75% of LRF; 72,54% of CRF with microwave radiation at a power of 1000W, 27,46% of LRF. The techniques used for characterization of CRF were: Fourier transformed infrared (FTIR) spectroscopy and X-ray diffractometry (XRD) for crystallinity analysis and scanning electron microscopy (SEM). For characterization of LRF the techniques were used: UV-vis and FTIR spectroscopy. The use of NADES a low cost, sustainable organic solvent combined with microwave radiation proved to be efficient for biomass fractionation. |

El valor añadido de una refinería está asociado al tratamiento y la disgregación de los componentes de la biomasa. Existen procesos aplicados al fraccionamiento de la biomasa para eliminar o romper las capas de lignina y hemicelulosa, lo que permite que las enzimas accedan más fácilmente a la celulosa. Em vista de ello, se puede utilizar una amplia diversidad de rutas tecnológicas y técnicas alternativas que se han desarrollado, como el uso del disolvente eutéctico profundo natural (NADES). Así, el objetivo del presente trabajo fue realizar el fraccionamiento de la biomasa de la corteza de la especie de eucalipto E. urograndis en dos fracciones: fracción rica en celulosa (FRC) y fracción rica en lignina (FRL) mediante NADES. En este proceso se aplicaron tres condiciones para el fraccionamiento de la biomasa: calentamiento convencional a 100ºC, radiación de microondas con potencias de 600W y 1000 W, y temperatura ambiente a 25ºC. Los porcentajes obtenidos mediante calentamiento convencional fueron 72,25% de FRC, 27,75% de FRL; 72,54% de FRC con radiación de microondas a una potencia de 1000W, 27,46% de FRL. Las técnicas utilizadas para la caracterización del FRC fueron: la espectroscopia infrarrojo por transformada de Fourier (FTIR) y la difractometría de rayos-X (XRD) para el análisis de la cristalinidad y la microscopía electrónica de barrido (MEB). Para la caracterización del FRL se utilizaron las seguientes técnicas: UV-vis y FTIR. El uso de NADES, un disolvente orgánico sostenible y de bajo coste, combinado con la radiación de microondas, demostró ser efectivo para el fraccionamiento de la biomasa.O Brasil tem uma posição privilegiada como líder na utilização integral da biomassa vegetal porque possui a maior biodiversidade do planeta.
