Abstract

Procedimiento para la preparación de celulosa con baja concentración de lignina, caracterizado por una combinación de etapas, en que a) un material lignocelulósico es tratado con una solución acuosa que contiene un alcohol C₁₋₆ y tiene pH 10 a 14, a una temperatura inferior a 100ºC y la solución acuosa en la cual la lignina separada de la lignocelulosa esta disuelta, se separa de los sólidos que consisten en un material enriquecido en celulosa y hemicelulosa, b) la hemicelulosa es separada del material enriquecido con celulosa y hemicelulosa obtenida en la etapa a), c) el material obtenido en la etapa b) con menor concentración de hemicelulosa, es tratado en solución alcalina con un sulfito alcalino, alcalinotérreo o sulfito de amonio, tal como Na₂SO₃ y/o con oxígeno con lo cual se disuelve la lignina y se obtiene celulosa con baja concentración de lignina; y celulosa obtenida por el procedimiento.Process for the preparation of cellulose with a low concentration of lignin, characterized by a combination of stages, in which a) a lignocellulosic material is treated with an aqueous solution containing a C₁₋₆ alcohol and has pH 10 to 14, at a lower temperature at 100 ° C and the aqueous solution in which the lignin separated from the lignocellulose is dissolved, is separated from the solids consisting of a material enriched in cellulose and hemicellulose, b) the hemicellulose is separated from the material enriched with cellulose and hemicellulose obtained in the stage a), c) the material obtained in stage b) with a lower concentration of hemicellulose, is treated in alkaline solution with an alkaline, alkaline earth sulphite or ammonium sulphite, such as Na₃SO₃ and / or with oxygen whereby the lignin and cellulose with low concentration of lignin is obtained; and cellulose obtained by the process.
