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.

Abstract: LA PRESENTE INVENCIÓN SE REFIERE A UN MÉTODO PARA PRODUCIR FURFURAL Y EXTRAER LIGNINA DE UNA SOLUCIÓN DE BIOMASA HEMICELULÓSICA QUE COMPRENDE UNA CANTIDAD TOTAL DE AZÚCARES C5, QUE COMPRENDE LA ETAPA DE CALENTAR LA SOLUCIÓN DE BIOMASA HEMICELULÓSICA A UNA TEMPERATURA DE AL MENOS APROXIMADAMENTE 200 °C; ACIDIFICAR LA SOLUCIÓN DE BIOMASA HEMICELULÓSICA CON UN ÁCIDO PARA PRODUCIR EL FURFURAL EN FASE DE VAPOR; Y CONDENSAR EL FURFURAL PARA RECUPERAR FURFURAL EN SOLUCIÓN, EN DONDE EL FURFURAL SE PRODUCE EN UN RENDIMIENTO MOLAR TOTAL DE AL MENOS 70 % DE MOLES DE FURFURAL PRODUCIDO/LOS MOLES TOTALES DE AZÚCARES C5 PRESENTES EN LA SOLUCIÓN DE BIOMASA HEMICELULÓSICA INICIAL. LA LIGNINA DE BAJO PESO MOLECULAR PUEDE RECUPERARSE A PARTIR DE LA SOLUCIÓN DE BIOMASA HEMICELULÓSICA ANTES DE LA PRODUCCIÓN FURFURAL MEDIANTE CONCENTRACIÓN DE MEMBRANA, ACIDIFICACIÓN, COAGULACIÓN Y FILTRACIÓN.
