Patent ID: 8540939

Claim:
A continuous flow device ( 50 ) for executing a process of preparation of nanostructures, the device ( 50 ) comprising: a first feeding unit ( 1 a ) with a first feed pump ( 9 ) connected to a first raw material source ( 7 ); a second feeding unit ( 1 b ) with a second feed pump ( 10 ) connected to a second raw material source ( 8 ); a first reactor unit ( 2 ) with a first reactor-zone unit ( 13 ) configured to receive material from the first feeding unit to heat to a given first temperature value and to feed into a first cooling unit ( 14 ) comprising a first countercurrent heat-exchanger configured to provide an enhanced rate of heat exchange to decrease particle size of nanostructures being prepared by the device; a mixing unit ( 5 ) configured to receive an output from the first cooling unit ( 14 ) and second raw material from the second feeding unit ( 1 b ); a second reactor unit ( 3 ) with a second reactor-zone unit ( 15 ) configured to receive output from the mixing unit ( 5 ) and to be heated to a given second temperature value to feed into a second cooling unit ( 16 ) comprising a second countercurrent heat-exchanger configured to provide an enhanced rate of heat exchange to decrease particle size of nanostructures being prepared by the device; at least one pressure controller ( 18 ) arranged in a flow path defined by the first reactor unit ( 2 ) and the second reactor unit ( 3 ) and configured to set a pressure value in the flow path; a control unit ( 22 ) configured to control at least one of the pressure value set by the pressure controller ( 18 ), the given first temperature value, and the given second temperature value; wherein the respective cooling units ( 14 , 16 ) are configured to terminate the process of preparation of nanostructures.
