ABSTRACT:
Lignocellulosic carbonaceous material is activated to produce a high activity, high density gas-phase activated carbon under conditions which effectively alter the particle pore volume size distribution to optimize the carbon's mesoporosity. An improved process is disclosed for producing the carbon, as are its application in emission control for vehicles.
