Abstract

Un proceso para deslignificar una biomasa; dicho proceso comprende los pasos de: proporcionar un recipiente; proporcionar una biomasa que comprende fibras de lignina, hemicelulosa y celulosa en dicho recipiente; proporcionar una composición ácida acuosa que comprende un componente de ácido sulfúrico; proporcionar un componente de peróxido; exponer dicha biomasa a dicho componente de ácido sulfúrico y componente de peróxido, creando una masa de reacción; permitir que dicho componente de ácido sulfúrico y dicho componente de peróxido entren en contacto con dicha biomasa durante un periodo de tiempo suficiente como para que se produzca una reacción de deslignificación y eliminar más del 90% en peso de dicha lignina y hemicelulosa de dicha biomasa; y controlar la temperatura de la reacción de deslignificación para mantenerla por debajo de los 55ºC.
