Abstract

Un proceso para producir celulosa reactiva a partir de biomasa lignocelulósica que tiene un contenido de hemicelulosa y un contenido de lignina, que comprende las etapas de: (a) pretratar la biomasa lignocelulósica con vapor; (b) mantener la biomasa lignocelulósica a una presión equivalente a una presión de vapor saturado a una primera temperatura preseleccionada hasta conseguir un grado preseleccionado de hidrólisis de hemicelulosa; (c) comprimir la biomasa pretratada a presión para retirar de 80 a 90 % del hidrolizado de hemicelulosa, obteniéndose biomasa extraída pretratada; (d) poner en contacto la biomasa extraída pretratada con un disolvente para hidrolizar y disolver la lignina en la biomasa extraída pretratada; (e) mantener la biomasa extraída pretratada en contacto con el disolvente durante un periodo de tiempo seleccionado a una segunda temperatura preseleccionada; (f) lavar la mezcla de biomasa pretratada a presión con disolvente adicional para retirar la lignina de la mezcla de biomasa pretratada y obtener una biomasa lavada con disolvente; (g) someter la biomasa lavada con disolvente a descompresión explosiva para obtener una corriente de celulosa purificada y una corriente de vapor; y (h) recoger la corriente de celulosa purificada y recuperar el disolvente en la corriente de vapor.
