Abstract

A new reactor for carbon black production has been revealed. A new method for producing carbon black. and a new type of carbon black Carbon black is characterized by an ideal surface area in the range of 70 to 150 m/g and a "G" value of less than 1.20 or greater than 1.05 corresponding to the size distribution. Very narrow or very wide granules, respectively. Ideally, the reactor would It is used for the axial flow of combustion gases and is characterized by The measurement is series, the boundary of the cylindrical combustion, the convergent convergent zone, the neck, the abrupt convergence zone. and the cylindrical pyrolysis zone. In some aspects of this invention, the combustion gas is generated by the combustion of low-BTU fuels and gasification. These pass through the neck at speeds close to 1 Mac in one method. Carbon black production The raw material is brought into the convergence zone, on the other hand, the raw material is introduced in aerosol form, in the other method, the raw material is imported by composition with countercurrent or current speed.
