Abstract: One- ann two-stage processes to obtain furfural from rice hull were examined. I When the reaction was carried out in am autoclave at different liquid/solid ratios and sulphuric acid concentrations, a low production of furfural was observed Metallic oxides catalysed the conversion ann 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. (C) 1998 Published by Elsevier Science Ltd. All rights reserved.
