Abstract
a presente invenção refere-se a um processo de pré-tratamento da biomassa lignocelulósica, compreendendo o contato da biomassa lignocelulósica com a solução de pré-tratamento em uma temperatura que varia de uma temperatura ambiente até 100°c e uma pressão de pelo menos 2 mpa (20 bar), em que a solução de pré-tratamento compreende água, solvente orgânico miscível em água e álcali tendo uma concentração de 5 a 15% p/v se o álcali for sólido ou 5 a 15% v/v se o álcali for líquido. dito processo de pré-tratamento opera em condições suaves ou em temperatura baixa para ser específico com a remoção de lignina, mas sem destruir a celulose e aumentar o rendimento de açúcar desejado.
