Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>Suitable solid adsorbents are demanded for carbon capture and storage (CCS) processes. In this work, a novel microporous polymer is developed by hypercrosslinking of organosolv lignin, which is a renewable resource. Reaction with formaldehyde dimethyl acetal (FDA) via Friedel–Crafts reaction gives microporous networks, with moderate capacity of carbon dioxide but excellent selectivity towards CO₂/N₂ mixture as predicted on the basis of ideal adsorption–solution theory (IAST). Pyrolysis of pure organosolv lignin results in microporous carbon powders, while pyrolysis of hypercrosslinked organosolv lignin yields shape‐persistent materials with increased CO₂ capacity while maintaining very good selectivity.</p> </abstract>
