Carbon black, method for manufacturing carbon black and device for performing the method

Carbon black with an aggregate size distribution ratio ((d 9 0-d 1 0)/d 5 0) of = 1.1, is new. Independent claims are included for: (1) preparation of the carbon black; and (2) device for executing the above process comprising a burner and a cooling surface against which the flame is directed, where...

Zusammenfassung:	Carbon black with an aggregate size distribution ratio ((d 9 0-d 1 0)/d 5 0) of = 1.1, is new. Independent claims are included for: (1) preparation of the carbon black; and (2) device for executing the above process comprising a burner and a cooling surface against which the flame is directed, where the cooling takes place through a self-constricting gap, which has a height/width ratio of 1-100 mm, where the width is related to the upper edge of the gap and is 0.5-10 mm and the flow velocity at the narrowest point of the gap is 10-200 m/s.
