Abstract: 

Dissolution and fractionation of lignocellulosic material is a critical step of valorization of lignins. Black liquor is very important stream in the production of kraft pulp and plays a key role in economic balance of lignocellulosicbiorefinery. Presented work deals with the isolation of the lignin from the black liquor by the precipitation method, using a variety of acids and different pH.
