| Abstract: | Furfural was prepared from hemicelluloses and lignocellulosic biomass in the presence of theγ-valerolactone/water solvent system with low cost sulfate as catalyst.The yield of furfural could be obtained as high as 50.2%,accompanying with 95.5% of hemicellulose conversion.Furthermore,furfural also could be prepared from real lignocellulosic biomass corncob and bamboo meal in the above catalytic system with the yield of 39.5% and 29.7%,respectively.In this case,corncob and bamboo meal conversion could be 86.5% and 80.50%. |
