Abstract

SISTEMA DE REATOR COM DOIS VASOS E MÉTODO PARA HIDRàLISE E DIGESTçO DE CAVACOS DE MADEIRA COM MÉTODO DE LAVAGEM QUÍMICA APRIMORADO. A presente invenção refere-se a um sistema de vaso do reator que inclui: um primeiro vaso do reator que tem um hidrolisado e uma tela de extração de líquido, uma primeira região acima da tela de extração que é mantida em condições que promovem uma reação de hidrólise no material celulósico, uma segunda região abaixo da tela de extração em que a hidrólise é substancialmente suprimida e uma entrada de-líquido de lavagem abaixo da tela de extração que proporciona líquido de lavagem em uma temperatura abaixo de uma temperatura de hidrólise; um tubo de transporte que tem uma entrada acoplada ao primeiro vaso do reator e uma saída acoplada a um segundo vaso do reator, e o segundo vaso do reator inclui uma descarga de líquido que extrai uma parte do líquido do segundo vaso do reator e direciona a parte do líquido para o primeiro vaso do reator ou para o tubo de transporte.
