Abstract

processo para produzir etanol. a presente invenção refere-se a um produto de etanol bruto obtido da hidrogenação de ácido acético compreende etanol e acetato de etila. usando um coluna de destilação operada em uma pressão de 0,1 a 100 kpa, o acetato de etila e o etanol podem ser eficazmente separados. além disso, mantendo a quantidade de água que é alimentada para a coluna de destilação em uma quantidade menor do que 10%em peso, com base no peso de todos os componentes alimentados para a coluna de destilação, provê um benefício de energia.
