Thermal carbon black process

Claim 1

A CONTINUOUS THERMAL PROCESS FOR PRODUCING CARBON BLACK WHICH COMPRISES BURNING A COMPLETELY COMBUSTIBLE MIXTURE OF FUEL AND AIR IN SEPARATE MULTIPLE RADIANT FLAMES FIRING DIRECTLY AGAINST THE INNER SURFACES OF TWO CLOSELYSPACED PARALLEL REFRACTORY WALLS MAINTAINED WITHIN A HEATINSULATED CHAMBER TO HEAT THE SURFACES TO INCANDESCENCE, SAID WALLS DEFINING A SHALLOW REACTION ZONE, SAID FLAMES BEING DIRECTED SUBSTANTIALLY PERPENDICULARLY TO AT LEAST ONE OF SAID WALLS AND BEING DEFLECTED THEREBETWEEN, FLOWING A HYDROCARBON IN THE GASEOUS STATE THROUGH SAID SHALLOW REACTION ZONE, THERMALLY DISSOCIATING THE HYDROCARBON TO CARBON BLACK AND GASEOUS BY-PRODUCTS IN SAID REACTION ZONE BY THE HEAT RADIATED FROM SAID REFRACTORY WALLS, ENTRAINING THE CARBON BLACK THUS PRODUCED IN THE COMBUSTION PRODUCT AND BY-PRODUCT GASES AS AN AEROSOL AND CONVEYING SAID CARBON BLACK OUT OF THE REACTION ZONE AND INTO A LOWER AREA OF THE CHAMBER, SEPARATING A PORTION OF THE CARBON BLACK FROM THE AEROSOL BY GRAVITY SETTLING IN THE LOWER AREA OF SAID CHAMBER, AND REMOVING THE CARBON BLACK AND ATTENUATED AEROSOL SEPARATELY OUT OF THE CHAMBER.
