  • PROCESS FOR PRODUCING LIGNIN PARTICLES
    Publication number: 20210261742
    Abstract: Described is a process for producing lignin particles in the context of a continuous process, including 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, and the residence time in the mixing apparatus does not exceed a duration of 30 seconds.
