1. 1. Lignin Extraction from Black Liquor - Properties of the Liquors and Sulphur Content in the Lignin

   Författare :Ali Seid Moosavifar; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heat-treatment; lignin precipitation; boiling point elevation; lignin; alkalisation; biofuel; properties; viscosity; Black liquor; combustion of lignin; lignin modification; viscosity correlations.;

   Sammanfattning : Kraft lignin isolated by precipitation can be considered as being a valuable renewable source of energy and material. Removing lignin from black liquor is also advantageous as it decreases the load on the recovery boiler, which is usually the limiting factor in the production of kraft pulp. LÄS MER
