Abstract: La invencion se refiere a un procedimiento para la granulacion continua en seco de negro de humo en polvo. La granulacion tiene lugar con ayuda de un granulador. En contraposicion a los tambores para formar perlas utilizados hasta el presente, se puede en una magnitud de aparato comparable, aumentar multiples veces el paso de negro de humo.

Abstract: A continuous drying process for powdered lampblack, comprises: (i) passing the lampblack through a helical granulator assembly which is formed by a helical sequence of metal quills whose maximum tip speed is 1-6 m/s; (b) allowing an average residence period for the powder of 20-600 seconds; (c) inoculating the raw incoming lampblack with 50 % preferably 5-30% granular lampblack (9); (d) pre-compressing the raw incoming lampblack to 150-300 g/l; and (e) using a dry pearl drum after the helical granulator.

Abstract: Inverzní saze, které mají menší valivý odpor při stejně dobrém nebo lepším chování za vlhka a distribuce velikosti částic má menší zastoupení částic s velkými průměry. To vedeke zlepšení oděrového chování pryžových sloučenin, které se připravily za použití těchto sazí. Způsob výroby inverzních sazí v běžných sazných reaktorech kontrolou spalování ve spalovací komoře, při které dojde k tvorběsazných jader, která se okamžitě uvedou do kontaktu se surovým sazným materiálem. Saze vykazují nižší zastoupení větších částic, pokud se vhodným způsobem zvýší přívod spalovacího vzduchu a surového sazného materiálu.

Abstract: Furnace carbon black which has an H content of greater than 4000 ppm and a peak integral ratio of non-conjugated H atoms (1250-2000 cm-1) to aromatic and graphitic H atoms (1000-1250 cm-1 and 750-1000 cm-1) of less than 1.22. It is produced by injecting the liquid carbon black raw material and the gaseous carbon black raw material at the same point in a furnace carbon black process. The furnace carbon black may be used in the preparation of electrocatalysts.

Abstract: Carbon black beads, which contain natural and/or synthetic wax and are produced by granulating carbon black powder, have a wax content of 1 to less than 10 wt.% and a hardness greater than 0.15 N. An Independent claim is also included for the continuous production of the beads. The beads are produced in a heated granulator with a toothed shaft and inlet, granulation and outlet zones. The carbon black powder is fed into the inlet zone. Molten wax or wax mixture with an average droplet size NOTGREATER 50 micron is sprayed into the first third of the granulation zone. The shaft operates at a maximum peripheral velocity of 1-6 m/s and the average residence time of the carbon black in the machine is 20-600 seconds.

Abstract: The inventive carbon black is characterised by an STSA surface of between 20 and 180 m /g, a 24M4-DBP-absorption of between 40 and 140 ml/100g, a specific BET surface of between 20 and 250 m /g, in that it contains 0.01 to 20 wt % silicon in relation to its total weight and in that it has a ratio of tan delta 0/tan delta 60 greater than 3.37-0.0068•STSA. The inventive carbon black is produced by adding silicon-containing compounds are added and mixed with the of carbon black raw material during the oxidative pyrolysis of the same and optionally, using carbon black oil as the fuel. The inventive carbon black can be used as a filler in rubber mixtures, preferably for tyres.
