DEVICE TO PRODUCE CARBON MATERIAL WITH NANOSTRUCTURED CARBON BY BLAST Russian patent published in 2011 - IPC C01B31/02 B82B3/00 

FIELD: process engineering.

SUBSTANCE: invention relates to production of common and nanostructured carbon. Proposed device comprises reaction tubular round-section channel in the form of closed loop with two straight sections connected by smoothly bent section, branch pipe to feed inert gas into reaction channel that is arranged on one straight section, branch pipes to feed oxygen with blast initiator, hydrogen and carbon-containing compounds that are arranged on opposite straight section clockwise from inert gas feed branch pipe, and branch pipe to discharge reaction products. Catalytic reactor made up of cylinder with perforated webs with catalyst applied thereon is mounted in reaction channel, counter clockwise and behind the inert gas feed branch pipe. Length of said straight sections makes, no less than channel's 15 diametres. Inert gas feed branch pipe features diametre equal to that of reaction channel, and is arranged at the distance of at least 25 diametres of carbon-containing compound feed branch pipe. Oxygen feed branch pipe features diametre equal to half the OD of reaction channel, and is arranged at the distance of at least 25 diametres of carbon-containing compound feed branch pipe. Hydrogen feed branch pipe features diametre making 1/3 of reaction channel OD and is arranged at the distance of 4-5 OD of reaction channel from oxygen feed branch pipe. Hydrogen feed branch pipe features diametre making 1/2 of reaction channel OD and is arranged at the distance of 4-5 OD of reaction channel from oxygen feed branch pipe. Axes of said branch pipes are located perpendicular to straight section axis, reaction product discharge branch pipe features diametre equal to reaction channel OD, and is arranged aligned with straight section. Catalytic reactor is arranged at the distance of 1 to 2 reaction channel OD from inert gas feed branch pipe and features diametre equal 2 to 3 reaction channel OD and length making 5 to 10 reaction channel OD, while the number of perforated webs varies from 4 to 5.

EFFECT: possibility of combined use of blast and catalyst to produce highly dispersed common and nanostructured carbon, reduced dynamic loads on device walls.
