Abstract
patente de invenção: "processo de produção de álccois e/ou de solventes, a partir de polpas de papel com reciclagem do vegetal não hidrolisado em um reator de regeneração". a presente invenção refere-se a um processo de produção de álcoois e/ou solventes, a partir de biomassa celulósica ou lignocelulósica, compreendendo pelo menos as seguintes etapas; a) pré-tratamento químico alcalino de um substrato celulósico ou lignocelulósico; b) eventualmente lavagem do substrato pré-tratado; c) hidrólise enzimática do substrato pré-tratado e eventualmente lavado, utilizando enzimas celulolíticasd e/ou hemicelulolíticas, produzindo um hidrolisado e um resíduo insolúvel na água; d) fermentação por micro-organismo do hidrolisado oriundo da etapa c) e obtenção de um mosto de fermentação contendo pelo menos um álcool e/ou solvente; e) separação/purificação do álcool e/ou solvente e f) separação de um bolo contendo o resíduo insolúvel na qual pelo menos uma parte do bolo obtida na etapa f) é enviada em pelo menos um reator de regeneração da celulose, antes de ser reciclada a jusante da etapa a) de pré-tratamento químico alcalino.
