ACTIVATED CARBON

摘要

PURPOSE:To provide activated carbon excelling in adsorptivity and suitable for many uses, such as water treatment. CONSTITUTION:Phenol resin foam is carbonized at 800 to 1300 deg.C to form isotropic porous carbon material where an average pore diameter is 35 to 210mum and the pores having a diameter of <=1/2 and >=2 average pore diameter are >=10% each of the whole and part having continuous pores almost in the shape of a sphere and having pore wall thickness of <=2Omum is >=80% of the whole. The isotropic porous carbon material is activated to form activated carbon.
