At this point the furfural concentration is lower than 1.0g/L, but in the entire gradient heating process, reducing sugar concentration peak of furfural concentration peak appears in the temperature lower, can realize the separation of the reducing sugar and furfural good, reduce the inhibition of fermentation by- products such follow-up treatment process.
