  • Carbonaceous material with high micropore and low macropore volume and process for producing same
    Patent number: 5071820
    Abstract: A method which minimizes macropore formation while producing microporous carbon comprises a two stage process. Firstly, the carbon is heated to a temperature in the range of about 150.degree. to about 200.degree. C. in the presence of oxygen for a time in the range of about forty-five to about seventy-five minutes, then purging the reaction environment of oxygen at this temperature with nitrogen. In the second stage, the carbon is heated to a temperature in the range of about 750.degree. to about 900.degree. C. under a stream of nitrogen for a time in the range of about fifteen to forty-five minutes. The process is repeated a number of times, the number being dependent on the extent of microporosity desired.
