    Abstract: The present invention relates to a method of producing furfural and extracting lignin from a hemi-cellulosic biomass solution comprising a total quantity of C5 sugars, comprising the steps of heating the hemi-cellulosic biomass solution to a temperature of at least about 200°C; acidifying the hemi-cellulosic biomass solution with acid to produce the furfural in vapor phase; and condensing the furfural to recover furfural in solution, wherein the furfural is produced at a total molar yield of at least 70% of moles of furfural produced/the total moles C5 sugars present in the initial hemi-cellulosic biomass solution. Low molecular weight lignin can also be recovered from the hemi-cellulosic biomass solution prior to furfural production by membrane concentration, acidification, coagulation and filtration.
