ABSTRACT:
A process for preparing carbon blacks having lower-than-normal structure at a given surface area, and lower-than-normal surface area at a given overall combustion level. The process is carried-out by adding auxiliary hydrocarbons, which is hydrogen or any hydrocarbon having a molar hydrogen-to-carbon ratio greater than the molar hydrogen-to-carbon ratio of the feedstock, to the reaction zone of a carbon black reactor and adjusting the primary combustion and overall combustion so that the SSI of the process is less than zero.
