Abstract:
      From the aspects of domestic and foreign development history, technical characteristics and advantages, lignin product performance, etc., the most widely used and state-of-the-art lignin separation and extraction technologies—LignoBoost, LignoForce, and SLRP, are reviewed. The influences of the differences, advantages and disadvantages of the three technologies on the quality of correspondingly obtained lignin products are specifically highlighted and demonstrated. Finally, a general discussion on the comparison of the three technologies is given, and the future development trend is prospected.
