摘要
Carbon black is produced by feeding liquid hydrocarbon to the base of a vertical cylindrical refractory lined furnace so that it forms a pool in the base, feeding a combustion gas tangentially into the furnace to produce turbulent partial combustion of the vaporized hydrocarbon, and withdrawing products from the top. The combustion gas, e.g. air or O2, is preferably directed on to the surface of the pool, which may be an annulus on a convex base. The gas may be preheated by passing it through a jacket around the furnace, and is used in amount to produce 40-60% conversion. The hydrocarbon may be a gas, fuel, or lubricating oil of b.pt. above 150 DEG C. and average M.Wt of at least 150, and may be preheated by winding the feed line helically arround or within the walls of the furnace. Further reaction may occur in the upper part of the furnace or in a secondary chamber, upward flow being maintained by pressure differential. The furnace temperature may be 1000-1400 DEG C. Products are cooled by direct water quench, or indirectly on a tube cooler preferably with scrapers as described in Specification 1,123,741, and are separated by electrostatic filter e.g. as described in Specification 1,123,743.
