Abstract:
Novel carbon blacks that impart advantageous properties to rubber and plastic compositions and may be utilized in the place of lamp blacks, thermal carbon blacks and blends of carbon blacks. Also disclosed are novel rubber and plastic compositions incorporating the novel carbon blacks which exhibit the advantageous combinations of compound processing and physical performance properties.

Abstract:
This disclosure relates to an improved furnace process for producing carbon blacks by the incomplete combustion of hydrocarbonaceous feedstock wherein the resultant blacks have higher surface areas than the carbon blacks normally prepared from the feedstocks, as a result of which the blacks are particularly suitable for use in imparting conductivity properites to plastic materials and the like. This disclosure also relates to the production of a novel class of furnace blacks having excellent conductivity properites and which are characterized by high surface areas and low pH values.

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.
