Abstract

APERFEIçOAMENTOS EM PROCESSO DE HIDRóLISE áCIDA RáPIDA DE MATERIAL LIGNOCELULóSICO E EM REATOR DE HIDRóLISE, dito material lignocelulósico sendo alimentado em diferentes níveis de um reator (10) e contactado com fluxos de solvente orgânico de lignina, água e uma solução extremamente diluída de um ácido inogârnico forte, para obter uma fase líquida de extrato de hidrólise e uma fase sólida de material não reagido e não dissolvido. Um fluxo controlado de vapor é injetado nos diferentes níveis do reator, de modo a prover temperaturas adequadas de solvente orgânico e de ácido inorgânico forte e a formar os produtos (açúcares) desejados. Um fluxo da fase líquida é recirculado em diferentes níveis do reator. O remanescente da fase liquida é retirado do reator, resfriado bruscamente e submetido à evaporação do solvente para obter um concentrado dos produtos de reação, sendo a lignina transferida por decantação e sendo o concentrado transferido a etapas processuais subseqüentes.
