Claims
- 1. A method for producing microspherules of activated carbon, comprising kneading activated carbon particles of a size below 100 .mu.m, together with a dispersion of a water-insoluble synthetic resin to form an intimate mixture; pressing the mixture through a screen having holes related to the size of the desired microspherules; powdering the pressed material; and granulating and drying the resulting microspherules, the resulting microspherules having a diameter of from 0.1 to 1 mm.
- 2. A method according to claim 1, wherein the powdering is effected with graphite or activated carbon particles of a particle size below 100 .mu.m.
- 3. A method according to claim 1, wherein the powdering is effected with a pulverulent fireproofing agent.
- 4. A method according to claim 1, wherein the powdering is effected with metal powders.
- 5. A method according to claim 1, wherein the powdering of the extruded strands is effected directly after they emerge out of the screen.
- 6. A method of manufacturing microspherules from activated carbon, comprising uniformly distributing activated carbon with a preponderant particle size of less than 20 .mu.m through an aqueous dispersion of a synthetic resin that is insoluble in water and spray-drying the resulting mixture under conditions such that the temperature of the droplets or of the microspherules deriving therefrom does not exceed 120.degree. C., the resulting microspherules having a diameter of from 0.1 to 1 mm.
