ABSTRACT:
Carbonaceous adsorbent particles having multimodal pore size, including micropores and macropores, with improved adsorptive and separative properties, are prepared by partial pyrolysis of polysulfonated macroporous precursor resins, said resins being in turn derived from macroporous poly(vinylaromatic) resins. The particles may be further treated by activating with reactive gases or by functionalization.
