The current furfural production uses mineral acids at approx. 200 °C, providing around 50 mol% yield. These mineral acids possess several drawbacks, e.g., high toxicity, corrosiveness, difficult recovery and large salt waste after work-up. The purpose of this study is to replace the mineral acid with solid acid catalysts. This approach may offer several advantages over current processes in the conversion of pentosan derivatives e.g. xylose into furfural: high yields, facile separation and reusability of the catalyst. In the present study, different solid acid catalysts developed for this purpose (sulfated zirconia, alumina and Al-MCM-41), as well as commercial polymers have been tested to find a selective and stable catalyst.
The results of this work could be used to produce platform chemicals from sugar-based side-streams in the forestry industry, in particular from the pre-hydrolysate liquor for dissolving pulp. These obtained value-added products have applications in a wide range of industrial branches (biofuel, pharmaceutical, agrochemical, petrochemical and chemical industry, among others).
