International Classification:

C09C 150

US Classification:

423450

Abstract:

A process is provided for making high-quality carbon blacks at unusually good yields in a highly compact reaction space. The key steps of the process are the generation of a very hot combustion gas stream moving at very high speed in essentially plug flow by burning a hydrocarbon gas in oxygen in a compact combustion zone under conditions of very high heat release assuring the attainment of temperatures of over 3,000. degree. F. , and the transverse injection into said highspeed combustion stream from the periphery thereof of a plurality of individual streams of liquid hydrocarbon make, each of which is injected under sufficient pressure to cause same to enter said high-speed combustion stream at a linear velocity of more than about 100 fett per second. Preferably, a highly oxygen-enriched oxidant is used to burn the hydrocarbon gas.
