Abstract (en)
[origin: WO2020000008A1] Described is a process for producing lignin particles in the context of a continuous process wherein a particle-free lignin-containing solution and a precipitation agent are combined in a mixing apparatus and subsequently passed out of the mixing apparatus again, wherein a mixing efficiency of the lignin-containing solution with the precipitation agent of at least 90% and a precipitation of lignin particles are achieved to form a suspension of lignin particles, characterized in that the residence time in the mixing apparatus does not exceed a duration of 30 seconds.
