    摘要: Carbon black is produced in a flow reaction by spraying a hydrocarbon containing liquid feedstock with the aid of a propellant gas into a stream of hot reaction gases produced by burning a fuel, the feedstock-propellant gas-jet enters the reaction zone with a spraying angle that is greater than the spreading angle of a free jet. There is also described an apparatus for carrying out the process which comprises a binary injector supporting an atomizing nozzle whose head has several channels which are adjusted from zero degrees to different angles to the longitudinal axis of the nozzle.

    摘要: An oxidized carbon black (gas black) is prepared within the MCC (medium color channel black) area showing primary particle sizes of an average diameter of 16 to 18 nm and a content of volatiles of at least 15% which, as secondary characteristics, has a specific surface area (BET) of 300 to 420 m.sup.2 /g, an oil absorption (stiff paste) conducted on carbon black powder of 430 to 560 g/100 g, an oil absorption (stiff paste) conducted on carbon black beads of 370 to 450 g/100 g, a pH value of 2 to 5, a nigrometer index of 68 to 72 and a maximum content of volatiles of 25%. The carbon black is used as a pigment in high jet black lacquers.

    摘要: A process for the production of furnace blacks of variable carbon black structure according to the customary furnace black technology is disclosed, whereby a low ratio is adjusted between combustion air and carbon black raw material for achieving high yields and large raw material through-puts, and wherein for lowering of the carbon black structure the carbon black produced is removed entirely or partly from the exhaust gases and the residual gas thus obtained is completely or partially recycled to the combustion chamber of the reactor.
