Abstract

método para despolimerização catalisada por ácido de celulose. a presente invenção refere-se a um método para despolimerização catalisada por ácido de celulose que compreende um tratamento mecânico de celulose na presença de um ácido inorgânico e/ou orgânico. a conversão catalítica de celulose em produtos solúveis em água é conseguida de maneira virtualmen completa pelo fato de celuoligômeros, celobise, glicose e glicerol serem obtidos sem subprodutos siginificativos.
