Integral 90 wt% carbon-honeycomb lab-scale monoliths prepared from coal are characterized and applied to adsorb o -xylene. Textural characterization shows that the monoliths obtained after activation of the carbon exhibit appropriate porosity for their use as adsorbents. Their total capacity to retain o -xylene proves to be similar to that previously reported for studies under dynamic conditions on activated carbons but in the form of powder. .
