Abstract

Separación de pulpa de celulosa en distintas fracciones con diferentes características morfológicas y de drenaje; uso de parte de estas fracciones para producción de nanocelulosa. El proceso combina las operaciones individuales de separación de fibras, espesamiento hasta una determinada consistencia, drenaje y secado de la pulpa de celulosa con la capacidad de alto drenaje y la producción de nanocelulosa de pulpa de alto contenido de partículas finas primarias. Puede contemplar cualquier fibra de pulpa de celulosa derivada de maderas de fibra corta o larga, como eucalipto, Corymbia, abedul, álamo, pino, fibras recicladas, etc., sus residuos como corteza, serrín, etc.
