Abstract

La presente invención se refiere a un proceso para producir microcelulosa que comprende la hidrolización de material celulósico fibroso con un ácido a temperatura elevada o la acidificación de material celulósico fibroso seguida de lavado y la hidrolización del material celulósico lavado a temperatura elevada para producir una mezcla de microcelulosa- hidrolisato seguida de separación de la microcelulosa del hidrolisato, en donde la mezcla o el hidrolisato o microcelulosa separados se encuentran opcionalmente neutralizados, y en donde la producción de microcelulosa está integrada a la producción de una fábrica de pulpa de forma tal que al menos parte de los químicos utilizados en la acidificación, hidrólisis ácida y/o neutralización se produce mediante un proceso de recuperación química integrada de la fábrica de pulpa.
