Sumario:The production of furfural from renewable sources, such as lignocellulosic biomass, has gained great interest within the concept of biorefineries. In lignocellulosic materials, xylose is the most abundant pentose, which forms the hemicellulosic part. One of the key steps in the production of furfural from biomass is the dehydration reaction of the pentoses. The objective of this work was to assess the conditions at which the concentration of furfural is maximized from a synthetic, monophasic and homogeneous xylose medium. The experiments were carried out in a microwave reactor. FeCl3 in different proportions and sulfuric acid were used as catalysts. A two-level, three-factor experimental design was developed for this purpose. Results were further analysed through a second experimental design and optimization was performed by Response Surface Methodology. The best operational conditions for the highest furfural yield (57%) turned to be 210 ˚C, 0.5 min and 0.05 M FeCl3.
