Microwave-assisted production of furfural from the hemicellulosic fraction of olive stones
Olive stone (OS) is a lignocellulosic material obtained as a coproduct in the olive oil production industry, mainly composed of hemicelluloses, with xylose accounting for 24.4% by weight as the main sugar. In this study, an optimized process for obtaining furfural from OS was assessed. The process c...

| Sumario: | Olive stone (OS) is a lignocellulosic material obtained as a coproduct in the olive oil production industry, mainly composed of hemicelluloses, with xylose accounting for 24.4% by weight as the main sugar. In this study, an optimized process for obtaining furfural from OS was assessed. The process consists of two steps; the first one, aimed at maximizing the solubilization of xylose, was performed in an autoclave at 130ºC and 2.6 %w/v H2SO4, resulting in 83% xylose recovery in the liquid fraction. The second step, using the optimized liquid produced previously, was carried out in a microwave reactor at 200 ºC with the addition of 0.1 M FeCl3 from which a solution with 18 g/L furfural and 63.3% yield was obtained, equivalent to almost 90 kg of furfural per tonne of processed OS. As a conclusion, this underutilized lignocellulosic material can be considered as a promising renewable source of furfural. |
