Zusammenfassung:	The object of the present invention is carbon nanofibers mainly characterized by their high specific volume of mesopores, their high gas adsorption capacity and presenting a graphitic hollow structure. A second object of this invention is a procedure for obtaining such carbon nanofibers, which makes use of a metallic nickel catalyst and specific process furnace parameters that combined with the chemical composition of the furnace atmosphere and the fluidodynamic conditions of the gas stream inside the furnace, result in a faster growth of the carbon nanofibers and also in a higher quality of the carbon nanofibers obtained.
