|Abstract: ||One- and two-stage processes to obtain furfural from rice hull were examined. When the reaction was carried out in an autoclave at different liquid/solid ratios and sulphuric acid concentrations, a low production of furfural was observed. Metallic oxides catalysed the conversion and enhanced furfural production. In a two-stage process (pre-hydrolysis and dehydration) the yield was the highest and critical variables were solid/liquid ratio and acid concentration in the dehydration. Metallic oxides and chlorides increased the furfural production.|
