The Synthesis of Microporous Carbon in the Furfural–Hydroquinone–Urotropin System

The mutual solubility and polymerization in the furfural-hydroquinone-urotropin system were studied. Microporous carbon was obtained by activating the carbonized polymer with potassium hydroxide. It has been found that, depending on the mass ratio of KOH to carbonizing polymer, the specific surface area of the activated carbon varies from 2010 to 3307 m/g, and the micropore volume varies from 0.941 to 1.124 cm/g. The surface and porosity parameters of model carbon structures with homogeneous square or hexagonal pores were calculated. It is assumed that the micropore volume of the obtained activated carbons is approaching the theoretical limit. The resulting coals can be used as effective adsorbents.
