METHOD FOR PRODUCTION OF FIBROUS CARBONIC STRUCTURES BY CATALYTIC PYROLYSIS Russian patent published in 2009 - IPC D01F9/127 B82B3/00 C01B31/02 D01F9/12 

FIELD: technological processes.

SUBSTANCE: in lower part of reactor disk connected to rotation drive is installed, above which settling chamber open at the bottom is located, in which catalyst is sprayed in the form of powdered nickel-based alloy. Initial product - carbureted hydrogen gas - is continuously supplied to reactor and heated up to 600-1,150°C, and gaseous products of pyrolysis are also continuously discharged. Finished product and catalyst are cooled down. Prior reactor putting into operation, sticky film is installed under settling chamber on disk, and spraying device is switched on. After catalyst supply has been stopped, film is cut in pieces, and amount of catalyst settled on unit of film area is determined, by results of which uniformity of powdered catalyst supply is controlled. Settling of powdered catalyst is realised when disk and rotation drive are switched off and pressure is reduced.

EFFECT: obtainment of maximum efficiency and quality of fibrous carbonic structures at different sizes of powdered catalyst particles.
