DE 19859896 A UPAB: 20000905 NOVELTY - In the production of activated charcoal beads or green moldings by mixing carbonaceous powder with a binder, mixing is carried out in a stirred vessel with rotary stirrer(s). USE - Activated charcoal beads are useful e.g. in stationary and fluidized beds. ADVANTAGE - Activated charcoal beads are better than extruded cylindrical pellets for some applications, as they have less tendency to form channels in stationary beds and have better flow in fluidized beds. However, an existing method of producing beads is very costly. The present method is simple and cost effective.
