Investigations into obtaining granulated sorbents based on bentonite clays of the Kyngrack fi eld have been carried out. A pilot-production technology for obtaining carbon composite materials (sorbents and catalysts) has been proposed. The process of formation of catalytic carbon in composites based on Ni–Mo bentonite has been studied on a semicommercial continuous laboratory reactor. It has been established that tubular-fibrous nanosize particles are predominantly formed in the pyrolysis of methane with a Ni–Mo-bentonite catalyst. The efficiency of activation of these sorbents is influenced by the concentration of the clay in them and by their temperature, and also by the consumption of an acid and the time of contact between the solvent and the acid. The structure of the formed nanotubes and nanofibers has been determined with a scanning electron microscope. Optimum parameters and kinetic regularities of the process of obtaining nanotubes and nanofibers at the intermolecular level through their pyrolysis from methane have been obtained.
