Abstract

1298938 Activated carbon LANCASHIRE TAR DISTILLERS Ltd 23 Dec 1969 [24 Dec 1968] 61325/68 Heading C1A Activated carbon is produced by carbonizing the residue from the solvent extraction of coal tar pitch with an aromatic solvent. Carbonization of the residue, which should be finely divided is carried out at temperatures greater than 600‹ C., for a period of half to one hour, preferably in an inert atmosphere. The aromatic solvent preferably contains N or O with an unshared electron pair, e.g. quinoline. Active carbon produced by this method may be further activated in known manner.
