Abstract
PROCESSO E SISTEMA DE PRODUÇÃO DE BIOGÁS A PARTIR DA DIGESTÃO ANAERÓBIA DE BIOMASSA VEGETAL EM FASE SÓLIDA A presente invenção refere-se a um processo de produção de biogás a partir de materiais lignocelulósicos, compreendendo as etapas de: (a)tratamento de biomassa vegetal através de explosão a vapor; e (b)hidrólise e digestão anaeróbia do material tratado na etapa (a) por bactérias anaeróbias em que as etapas (a) e (b) são realizadas em reatores separados, a etapa (b) é realizada em um único reator e os produtos da etapa (b) são o biogás e a biomassa digerida. Alternativamente, a hidrólise e a digestão podem ser realizadas em reatores separados. A presente invenção refere-se ainda a um sistema para a realização do processo de produção de biogás também objeto da invenção, o qual compreende: (i) um primeiro reator para o tratamento de biomassa vegetal através de explosão a vapor; e (ii) um segundo reator para a hidrólise e a digestão anaeróbia do material tratado na etapa (i) por bactérias anaeróbias.Em uma concretização preferencial, ambos os processos e sistemas da invenção podem adicionalmente compreender, no reator de hidrólise e digestão anaeróbia, enzimas celulases com ou sem adição de xilanases. Em uma configuração alternativa, a hidrólise pode ocorrer em reatores separados.
