Abstract

La presente invención describe un procedimiento que permite obtener glucosa a partir de la celulosa retenida en el papel reciclado mediante un proceso de degradación ácida de la celulosa, eliminando para ello la lignina y la hemicelulosa contenida en el papel reciclado. Las principales ventajas del procedimiento se refieren a la eliminación de la etapa de pretratamiento de la madera, el producto obtenido no requiere de celulosa virgen, se genera menor cantidad de residuos, no requiere de etapas de eliminación de productos intermedios o generados, entre otras.The present invention describes a process that allows glucose to be obtained from the cellulose retained in the recycled paper by means of an acid degradation process of the cellulose, eliminating for this purpose the lignin and the hemicellulose contained in the recycled paper. The main advantages of the procedure relate to the elimination of the pretreatment stage of the wood, the product obtained does not require virgin cellulose, less waste is generated, it does not require stages of elimination of intermediate or generated products, among others.
