METHOD OF PRODUCING NANO-STRUCTURED CARBON FIBRES AND APPARATUS FOR REALISING SAID METHOD Russian patent published in 2011 - IPC D01F9/127 D01F9/133 B82B3/00 

FIELD: chemistry.

SUBSTANCE: sprayed catalyst is deposited on the top surface of a rotating disc through the settling chamber of a reactor, heated to pyrolysis temperature, after which hydrocarbon gas is continuously supplied and gaseous pyrolysis products are removed, and at the end of the pyrolysis process, the end product is cooled together with the catalyst. When feeding into the settling chamber, the catalyst is stirred and aerated with an inert gas. The hydrocarbon gas is fed through a gas-distributing apparatus. Gas is released through an annular slit between the disc and the cowling of the gas-distributing apparatus. Gaseous pyrolysis products are removed through socket pieces in the top part of the housing. At the end of the pyrolysis process, heaters are switched off and the housing is cooled to a safe temperature, after which the disc rotary drive is switched on and the material treated with an agitator is moved by a scraper through a window in the bottom part of the housing and removed from the reactor through an auger-type storage bin, whose drive is simultaneously switched on with that of the disc. The apparatus for producing nano-structured carbon fibres has a housing fitted with heaters, in the top part of which there is a pipe for feeding hydrocarbon gas and a unit for feeding the catalyst, connected to the gas-distributing apparatus in form of an inverted funnel with a built-in settling chamber and a socket piece for outlet of pyrolysis products, and in the bottom part there is a window for unloading the ready product, above which there is a disc which is connected to a rotary drive and interacts with a fixed scraper. The gas-distributing apparatus is fitted with a cowling over the disc, on which an agitator which is kinematically linked to the disc is mounted, where agitator is mounted on the path of the disc in front of the scraper for unloading the end product through the window, which joins the auger-type storage bin fitted with an agitator. The batching unit is in form of a screw doser having a mixing device and an aerator-bridge breaking cone.

EFFECT: obtaining nano-structured carbon fibres with high output of the product and high quality.
