▎ 摘　　要

NOVELTY - Preparing carbon molecular sieve by using carbon material attached with carbon comprises heat-treating the carbon material with carbon under specific atmosphere, condensing and dehydrogenating the carbon-containing substance to form a polymer with cross-connection of the plane body of the condensed carbon net, washing and drying the polymer. USE - The method is useful for preparing carbon molecular sieve by using carbon material attached with carbon. ADVANTAGE - The method: has low energy consumption, innovates the preparation process of carbon molecular sieve; and can realize the high-value resource utilization of carbon materials attached to carbonaceous materials; and is economical.
