Abstract

um processo para hidrolisar biomassa lignocelulósica inclui alimentar a biomassa lignocelulósica em um reator de pré-tratamento, sendo que o reator de pré-tratamento tem um espaço livre carregado com dióxido de enxofre anteriormente utilizado no pré-tratamento de biomassa lignocelulósica. além disso, o ácido compreendendo dióxido de enxofre e/ou ácido sulfuroso é alimentado no reator de pré-tratamento (por exemplo, com a biomassa lignocelulósica, separado da biomassa lignocelulósica, ou uma combinação dos mesmos) e a biomassa lignocelulósica é aquecida. à medida que a biomassa lignocelulósica pré-tratada é descarregada do reator de pré-tratamento, ao menos uma porção do dióxido de enxofre utilizada no pré-tratamento é retida no espaço livre.
