Resumen
[ES] Actualmente, dentro del contexto de la economía circular, podemos utilizar aquellos subproductos y residuos agrícolas que no suelen tener valor, como recursos para obtener productos útiles para diferentes industrias como las biorrefinerías donde son utilizados como materias primas. Esta y otras biomasas lignocelulósicos pueden ser transformadas en bioenergía, biocompuestos, biocombustibles y otros compuestos de interés. Una de las formas de aprovechamiento del sarmiento de vid es la producción de furfural a partir de su fracción hemicelulósica. La producción de furfural se estudia a partir del rendimiento y conversión alcanzados en la reacción de deshidratación de xilosa. Determinamos las mejores condiciones en términos de temperatura, catalizador y su concentración para la producción de furfural a partir del sarmiento de vid. Los mejores resultados de producción de furfural se consiguieron tras pretratar los sarmientos con ácido sulfúrico y utilizando FeCl3 como catalizador a 200 °C en el tratamiento del licor en
microondas.
[EN] Nowadays in the context of circular economy, agriculture by-products are generalized utilized for a better use of available resources. These lignocellulosic biomasses can be converted into bioenergy, biocompounds and other products. Vine shoots are a very usual residual product in the Spanish vineyards with a lot of implications in biorefinery, using the lignocellulosic composition of these by-products. One of the ways of using them is the production of furfural from the hemicellulosic fraction. The proposal was to pretreat the biomass and then transform sugars obtained into furfural. The conversion rate, the selectivity, and the yield of the furfural produced are some aspects that were focused this investigation. According to the assesment of the different catalysts used, the highest furfural production has been achieved when vine shoots was pretreated with sulfuric acid and the resulting liquor was treated in microwave at 200oC using FeCl3 as a catalyst.
