Beschreibung
Zusammenfassung:	A new shaped activated carbon and the method of its manufacture are disclose d. The invention resides in the crosslinking of a polymeric cellulose, such as sodium carboxymethylcellulose (CMC), within the carbon bodies after they are shaped, employing the CMC as a binder for the activated carbon. The approach to attain product mechanical strength and water stability by crosslinking rather than high temperature heat treatment is not obvious from the prior ar t teaching. The crosslinking reaction occurs at temperatures below 270 ~C. In addition, this new binder technology produces shaped carbon bodies having ke y properties beyond the best level that has been accomplished with other binde rs.
