Interconnected porous monolithic materials can be directly obtained from non‐templating methods by reacting raw Kraft black liquor with epichlorohydrin either in the presence or not of surfactant, whereas extracted lignin leads to non‐porous materials. In the presence of a surfactant, micelles organization takes place and porosity of 40–60% can be achieved. Without surfactant, chemically induced phase separation occurs, giving materials with agglomerated nodules morphology. Carbonization followed by activation with CO 2 yield monolithic micro/mesoporous carbons with surface area of 300 m 2 g −1 . © 2014 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2015 , 132 , 41215.
