| 摘要 |
A highly microporous activated carbon is disclosed which is prepared by activation of an active carbon precursor material with a potassium hydroxide solution, pre-drying the blend to below 25% moisture content, activating this blend at from about 650 DEG to about 1100 DEG C., and acid washing and drying the microporous activated carbon product and which is characterized by greater than 50% of its total pore volume comprising pores of from above 8 ANGSTROM to 20 ANGSTROM in width and greater than 70% of its total pore volume comprising pores of less than 20 ANGSTROM in width and greater than 95% of its total pore volume comprising pores of less than 50 ANGSTROM in width.
