1. Concept development to extract sodium sulfate from an aqueous solution
University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikAbstract : Now when the interest is increasing to reach a sustainable infrastructure, one possibility SCA is experimenting with is the possibility to produce renewable hydrocarbons from black liquor which can be extracted from a Kraft process. However, when extracting the black liquor, a lot of sodium-based compounds are removed from the recovery process and when hydrocarbons are produced in SCA’s biorefinery, these compounds are caught in an aqueous solution.

2. Hydrogen Assisted Lignin Depolymerization with Pulp Mill Catalysts
University essay from Lunds universitet/Kemiteknik (CI)Abstract : As part of the development of a process for production of a lignin-rich oil that can serve as a renewable feedstock to existing petroleum refineries, hydrogen assisted depolymerization of lignin in filtered black liquor has been investigated. This process offers the possibility to reduce fossil emissions from transportation by utilization of the largest renewable carbon resource in Sweden, namely the forest. READ MORE

3. Towards Liquid Fuels from Lignin
University essay from KTH/Skolan för kemivetenskap (CHE)Abstract : The solubility of Lignoboost lignin was compared with softwood lignin precipitated from filtered black liquor and explained by Hilebrand as well as Hansen solubility parameters theory. The ability to dissolve efficiently lignin rises as the hydrogen bonding capacities together with the polarity of the solvents increases; similarly, their solubility parameter, according to Hildebrand, lay within the range between twelve and fourteen.
