A method for obtaining activated carbons from a partly mesophased and partly mesogenic pitch containing less than about 40% of the a resins, more than about 40% of type &#x3b2; resins and between about 5 and 30% of type &#x3b3; resins by activating the pitch preceded by its optional carbonization.

Activated carbons and method for obtaining same from a partly mesophase and partly mesogenic pitch

The invention relates especially to a process for the production of cold, comprising at least one stage of adsorption of carbon dioxide by an adsorbent solid substance and at least one stage of desorption of the carbon dioxide adsorbed in the said adsorbent substance, in which the said adsorbent substance comprises activated carbon fibers or an active charcoal and has a specific surface of at least 700 m.sup.2 /g and an external specific surface of at least 0.005 m.sup.2 /g.
