| 摘要 |
The invention relates to a process for producing furfural from xylose comprising: (a) mixing an aqueous xylose solution containing xylose oligosaccharides with sub-critical or near-critical water to form a mixture at a first temperature and a first pressure; (b) maintaining the mixture at the first temperature and the first pressure for a first time period; and (c) rapidly cooling the mixture to a second temperature and a second pressure, wherein furfural is produced by the process (d) process can also be carried out with or without mixing of carbon dioxide with aqueous xylose solution before it is mixed with sub-critical or near-critical water to form a mixture at a first temperature and pressure. |
