Abstract
novo método para produção de microcelulose. a presente invenção está correlacionada a um processo para produção de microcelulose, compreendendo a hidrólise de um material celulósico fibroso com um ácido sob elevada temperatura, ou acidificação do material celulósico fibroso seguido de lavagem e hidrólise de material celulósico lavado a uma elevada temperatura, para produzir microcelulose - mistura de hidrolisado seguido da separação da microcelulose do hidrolisado - em que a mistura ou o hidrolisado separado ou a microcelulose são opcionalmente neutralizados, e em que a produção da microcelulose é integrada à produção de uma unidade de fabricação de polpa, de modo que pelo menos uma parte dos produtos químicos usados na acidificação, hidrólise ácida e/ou neutralização seja produzida por meio de um processo integrado de recuperação química da unidade de fabricação de polpa.
