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.BIOGAS PRODUCTION PROCESS AND SYSTEM FROM SOLID PHASE ANAEROBIC VEGETABLE DIGESTION The present invention relates to a process of producing biogas from lignocellulosic materials comprising: (a) treatment of plant biomass by steam explosion; and (b) hydrolysis and anaerobic digestion of material treated in step (a) by anaerobic bacteria wherein steps (a) and (b) are performed in separate reactors, step (b) is performed in a single reactor and the products from step (b) are biogas and digested biomass. Alternatively, hydrolysis and digestion may be performed in separate reactors. The present invention further relates to a system for carrying out the biogas production process also object of the invention which comprises: (i) a first reactor for the treatment of plant biomass by steam explosion; and (ii) a second reactor for hydrolysis and anaerobic digestion of material treated in step (i) by anaerobic bacteria. In a preferred embodiment, both processes and systems of the invention may additionally comprise, in the anaerobic digestion and hydrolysis reactor, cellulase enzymes with or without added xylanases. In an alternative embodiment, hydrolysis may occur in separate reactors.
