Method for densifying a porous carbon preform (). The method includes the steps of: (a) providing the apparatus (); (b) charging the apparatus () with a plurality of stacks of annular porous carbon preforms (), the preforms being separated from one another by spacers (); (c) locating the charged apparatus () in a furnace at a temperature in the range of 950-1100&#xb0; C. and a pressure in the range of 5-40 torr; and (d) circulating a natural gas reactant blended with up to 15% propane through the apparatus for a period of from 150 to 900 hours.
