PCT No. PCT/EP91/01796 Sec. 371 Date Jun. 3, 1992 Sec. 102(e) Date Jun. 3, 1992 PCT Filed Sep. 20, 1991 PCT Pub. No. WO92/05868 PCT Pub. Date Apr. 16, 1992.A process for producing carbon molecular sieves for the separation of oxygen and nitrogen, whereby finely ground hard coal particles are oxidized with air in a fluidized bed, the coal is then formed after the addition of water and binders and carbonized at temperatures of 800 DEG -900 DEG C., subsequently activated with steam at temperatures of 800 DEG -900 DEG C. and the preliminary product of the low-level activation is treated with carbon splitting hydrocarbons. Starches obtained by reacting agglutinized starches with sulphamates are used as binders.
