Abstract

- The influence of lignin and xylan interactions on the filtration properties of precipitated LignoBoost lignin is investigated. LignoBoost lignin was dissolved together with added xylan and then re-precipitated. The resulting lignin-xylan suspension was more difficult to filter than the original LignoBoost lignin, although the mix also formed more porous filter cakes. One of the possible explanations suggested by the findings presented in this paper is that xylan is sorbed at the surface of the lignin agglomerates, increasing the contact area between solid and liquid and making the particles local structure more porous.
