Since the capacity of an adsorbent is expressed in terms of the surface area or the amount adsorbed per weight unit, high-density adsorbents are required. The dried leftover lignocellulose of furfural production, due to its good self-binding properties, can be granulated or pelletized and used as a potential raw material for production of highdensity activated carbon sorbents with double density, in comparison with activated carbon from charcoal. These high-density microporous sorbents are appropriate for purifying gaseous media. The chemical and mechanical pre-treatment of lignocellulose imparts new properties to the porous structure of the carbon material and to the activated carbon prepared from it.
