Abstract
A process for producing a molecular sieve carbon, which comprises subjecting a cured product obtained by curing a raw material thermosetting resin to heat oxidation; pulverizing the oxidized product formed after the heat oxidation treatment; granulating the resulting pulverized product; subjecting the resulting granule to carbonization; subjecting the carbonized charcoal obtained in the carbonizing step to heat treatment; and adjusting the pore size of the heat-treated carbonized charcoal.
