Abstract

"MéTODO PARA A SEPARAçãO DE áCIDO A PARTIR DE AçúCARES" é revelado um método para separar ácido e açúcares obtidos a partir de líquidos resultantes da hidrólise ácida de um material que contém pelo menos um dentre celulose e hemicelulose, que compreende adicionar os líquidos a uma unidade de separação que contém um leito de material de troca aniónica ou de exclusão cromatográfica por meio do qual o ácido é adsorvido por sobre o material cromatográfico, produzindo desse modo uma série de frações iniciais contendo soluções de açúcar e uma série de frações posteriores contendo soluções ácidas. é também revelado um processo para a produção económica, e de eficiente energia de etanol a partir de rejeito sólido municipal e outros suprimentos celulósicos.
