AN IMPROVED PROCESS FOR THE PRODUCTION OF CHANNEL CARBON BLACK COMPRISING THE STEPS OF FIRST FORMING AN AEROSOL OF A COMBUSTIBLE GAS AND A LIQUID HYDROCARBON BY CONTINUOUSLY INTRODUCING AN ATOMIZED SPRAY OF THE LIQUID HYDROCARBON, AMMONIUM CHLORIDE VAPORS AND A STREAM OF THE GAS INTO A HEATED SPACE, VAPORIZING THE LIQUID HYDROCARBON THEREIN, CONDENSING THE LIQUID HYDROCARBON UPON THE NUCLEI NORMALLY PRESENT IN THE GAS AND ADDITIONALLY PROVIDED BY THE AMMONIUM CHLORIDE VAPORS, AND SETTLING OUT THOSE LIQUID HYDROCARBON PARTICLES WHICH ARE TOO LARGE TO REMAIN SUSPENDED IN THE GAS STREAM, THEN CON-
