Abstract: Activated carbon is produced from lignite coke. It is characterized by the product of the molasses number times the iodine number divided by 1000 being 350 to 1000 and/or the product of the molasses number times the methylene blue number divided by 10 being 500 to 1200. It is produced by adding aqueous alkali or alkaline earth carbonate solution and/or aqueous alkali or alkaline earth hydroxide solution by means of lance during the steam activation of lignite coke in a rotating tube.

Abstract: An oxidatively aftertreated carbon black has a content of volatile constituents of more than 10 wt. %, based on its total weight, and the ratio of its CTAB surface area to the iodine adsorption number is greater than 2 m2/mg. The carbon black may be a channel black oxidatively aftertreated with ozone. The carbon black according to the invention is used preferably as pigment carbon black for the production of water-based paints, printing inks and as inks for mechanical and manual recording and drawing instruments. The combination of properties imparts to the carbon black an excellent dispersibility in water-based binder systems. The paints, printing inks and printer inks produced from this carbon black have an outstanding stability in storage.
