Abstract
The present invention is a synthesis, product and process for activated carbon and preferably carbon molecular sieve separation of air to produce a nitrogen product wherein a carbon is partially pyrolyzed, impregnated with a transition metal salt and further pyrolyzed to develop enhanced microporosity. The resulting microporous carbon can then be activated with carbon dioxide or steam and then pore-sized by cracking of hydrocarbons on the carbon to produce a carbon molecular sieve.
