Abstract

pré-tratamento de alimentos lignocelulósicos para a produção de glicóis. trata-se de um processo para a preparação de glicóis a partir de uma biomassa sólida lignocelulósica que compreende celulose, hemicelulose e lignina em um sistema de reator, sendo que o dito processo inclui: a) colocar a biomassa sólida lignocelulósica em contato com um solvente orgânico que compreende um álcool de baixo ponto de ebulição e um ácido de pré-tratamento a uma temperatura que varia de cerca de 80 a cerca de 220 °c e uma pressão que varia de 1 a 50 bar (absoluta) por um tempo que varia de cerca de 5 minutos a cerca de 2 horas para obter uma primeira mistura; b) separar a primeira mistura obtida na etapa (a) em um resíduo sólido pré-tratado que compreende celulose e uma corrente líquida que compreende lignina e hemicelulose dissolvidas; c) submeter o resíduo sólido pré-tratado a uma reação de hidrogenólise e gerar uma corrente de glicóis, uma corrente de componentes leves e uma corrente de componentes pesados; d) reciclar pelo menos uma parte da corrente de componentes leves na etapa (a), em que o corrente de componentes leves compreende uma primeira porção do solvente orgânico; e) separar pelo menos parte da corrente líquida da etapa b) para produzir uma segunda porção do solvente orgânico e um resíduo sólido que compreende lignina e hemicelulose; e f) reciclar pelo menos uma parte da segunda porção do orgânico na etapa (a), em que a primeira mistura tem mais do que cerca de 20% em peso de água.
