资源简介：
The present invention relates to a process for producing a nanocellulosic material based on fractioning a cellulosic pulp stream originating from pre-treatment or from mechanical defibrillation (partially refined/defibrillated pulp) in combination with stages of mechanical defibrillation， wherein both the oil fraction and the waste fraction can be conveyed to different consistency adjustment stages prior to a further stage of defibrillation. For example， where the oil is destined for an adjustment of consistency prior to a second stage of defibrillation whilst the waste is destined for a further independent consistency adjustment stage after which it returns to the first mechanical defibrillation stage.
