Abstract:
1. A process for producing an activated carbon spherule comprising: continuously pre-carbonizing a starting material which comprises a polymer spherule wherein said polymer spherule is based on styrene and divinylbenzene and comprises chemical groups which form free radicals and cross linkages by thermal decomposition, the continuous pre-carbonization being performed in a rotary apparatus working continuously at a temperature of from 100° C. to 850° C. to form a pre-carbonized polymer spherule; and subsequently discontinuously treating said pre-carbonized polymer spherule in a re-carbonization and activation step to produce the activated carbon spherule, the re-carbonization and activation being performed in a second rotary apparatus operating at a temperature of from 850° C. to 950° C.
