Abstract
This disclosure relates to an improved furnace process for producing carbon blacks by the incomplete combustion of hydrocarbonaceous feedstock wherein the resultant blacks either have higher surface areas than the carbon blacks normally prepared from the feedstocks or are produced more economically. The blacks produced by the process are suitable for use in all of the typical applications such as rubber plastics, inks and the like.
