Abstract
processo para a produção de álcool a presente invenção refere-se a um processo para produção de álcool a partir de um material celulósico, o referido processo compreendendo as etapas de: (i) hidrolisar o referido material celulósico com um ácido aquoso para produzir um hidrolisado; (ii) extrair ácido e água do referido hidrolisado com um solvente de extração orgânico miscível com água para produzir (a) uma primeira solução aquosa ácida contendo o referido solvente de extração e (b) um resíduo contendo açúcares; (iii) submeter o referido resíduo a uma reação de clivagem de oligossacarídeos para produzir uma solução aquosa de açúcares fermentáveis; (iv) fermentar os referidos açúcares fermentáveis e destilar álcool da mistura fermentada resultante; (v) evaporar o referido solvente de extração da referida primeira solução para produzir (a) uma segunda solução ácida aquosa contendo não mais de 1 0% em peso, preferivelmente não mais de 5% em peso, do referido solvente de extração e (b) solvente de extração gasoso; (vi) condensar o referido solvente de extração gasoso para reciclagem; e, opcionalmente, (vii) concentrar a referida segunda solução ácida aquosa para reciclagem; em que o referido solvente de extração é líquido na temperatura e pressão da etapa (ii), tem um ponto de ebulição de 25 a 60°c a uma pressão na faixa de o, 1 a 0,8 mpa (1 a 8 bar), e é tal que oligossacarídeos solúveis em água são precipitados da solução por sua adição na etapa (ii).
