Process for making carbon black
Morgan Allan C,Merrill E Jordan +1 more
TL;DR: In this paper, a process for making high quality carbon blacks at unusually good yields in a highly compact reaction space is described, where the key steps 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° F.

Carbon black manufacture
TL;DR: A gas-atomized spray of liquid hydrocarbon is injected vertically and coaxially into an elongated, heat-insulated furnace chamber located to a temperature in excess of the decomposition temperature of the hydrocarbon by passing hot gaseous products of combustion upwardly through the chamber adjacent the periphery thereof and so removed from the spray as to avoid infiltration there into of any unburned oxygen present therein this article.
