Abstract (en)

[origin: WO0136326A1] The invention concerns activated carbons. It further concerns a method for obtaining said activated carbons from a partly mesophased and partly mesogenic pitch. It concerns a method for obtaining activated carbons from a partly mesophase and partly mesogenic pitch containing less than about 40 % of type alpha resins, more than about 40 % of type beta resins and between about 5 and 30 % of type gamma resins by activating said pitch preceded by its optional carbonization.
