This disclosure relates to an improved furnace process for producing carbon blacks by the incomplete combustion of hydrocarbonaceous feedstock by varying the process described in U.S. Reissue Patent No. 28974 by carrying out the injection of a portion of the liquid hydrocarbon feedstock into the combustion gas stream as solid streams substantially radially at a location where the combustion gas stream has not attained maximum velocity whereby the resultant blacks have increased CDBP values and have properties which impart improved hysteresis to rubber formulations in which the blacks are incorporated.
