Method for producing furfural from lignocellulosic biomass material |
| 摘要 |
A method for producing furfural from lignocellulosic biomass material is provided, comprising (a) contacting the lignocellulosic biomass material with a mixture comprising water and an organic acid at a temperature of at least 100° C. and a pressure of at most 10 bar (absolute) to obtain a first liquid stream comprising hydrolyzed hemicellulose and a second stream comprising lignin and cellulose; (b) maintaining the first liquid stream comprising hydrolyzed hemicellulose at a temperature of at least 130° C. to obtain a second liquid stream comprising furfural; and (c) separating the furfural obtained in step b) from the second liquid stream. |

1. A method for producing furfural from lignocellulosic biomass material, comprising the steps of:
a) contacting the lignocellulosic biomass material with a mixture comprising water and an organic acid at a temperature of at least 100° C. and a pressure of at most 10 bar (absolute) to obtain a first liquid stream comprising hydrolysed hemicellulose and a second stream comprising lignin and cellulose; b) maintaining the first liquid stream comprising hydrolysed hemicellulose at a temperature of at least 130° C. to obtain a second liquid stream comprising furfural; and c) separating the furfural obtained in step b) from the second liquid stream, wherein part of the obtained first liquid stream comprising hydrolysed hemicellulose is recycled and contacted with lignocellulosic biomass material in step a). |
