  • Patent number: 4446108
    Abstract: High tint residual carbon black is produced in a vortex flow, venturi oil furnace carbon black reactor by charging the liquid feed or make hydrocarbon axially as a solid jet into a swirling mass of hot combustion gases upstream from the venturi and passing the hydrocarbon feed and hot combustion gases under carbon black forming conditions through the venturi section of the carbon black reactor.

  • Patent number: 4431624
    Abstract: A carbon black feedstock nozzle in which a central pipe with a diverging nozzle outlet is surrounded by at least one concentric annulus having a diverging nozzle outlet with a spray angle different from that of the central pipe and with means for supplying a separate controlled flow of inlet material to the central pipe and concentric annulus. In the preferred embodiment multiple concentric annuli surround the central pipe with the outermost annulus supplied with a coolant fluid as inlet material, and the other annuli supplied with hydrocarbon suitable as carbon black reactor feedstock. In a preferred embodiment means are provided for a seriatim cycling of flow through the various hydrocarbon feedstock annuli. A carbon black reactor in which a feedstock nozzle as described above discharges in a portion of the reactor that is either a precombustion section or a combustion section.

  • Patent number: 4402929
    Abstract: Carbon black having a high diphenylguanidine (DPG) value and a low pH value is produced in a reactor by separating the combustion gases into a plurality of streams by means of a perforate partition. This partition has a tubular portion or a conical portion which is surrounded by a plurality of through apertures at the downstream end. The hot combustion gases contact the make-hydrocarbon downstream of the partition. The combustion gases are introduced into the reactor upstream of the partition in a generally tangential direction for vortex flow while the make-hydrocarbon is introduced generally axially into the reactor.

  • Patent number: 4398582
    Abstract: A pneumatic tire having remarkably low rolling resistance and high wet skid resistance without deteriorating the wear resistance is obtained by using in at least the ground-contact area of its tread, a rubber composition consisting essentially of 100 parts by weight of a mixed elastomer and 40-80 parts by weight of carbon black, the mixed elastomer consisting of 10-60 parts by weight of a solution-polymerized styrene-butadiene copolymer rubber having a bonded styrene content of 5-30% by weight and a trans-1,4 content in butadiene unit of not more than 45% by weight; 10-50 parts by weight of an emulsion-polymerized styrene-butadiene copolymer rubber having a bonded styrene content of 30-50% by weight; and 0-80 parts by weight of at least one rubber having a glass transition temperature of not higher than -50.degree.

  • Patent number: 4391789
    Abstract: Disclosed is a method of making a carbon black product having a controllable aggregate particle size distribution comprising forming in a first zone of the carbon black reactor combustion gases at a high temperature and having a gradient of increasing turbulence in the downstream direction, injecting substantially radially into the first zone a carbon black feedstock into more than one of the "zones of increasing turbulence" before the gases reach maximum turbulence, cracking the feedstock to carbon black in a second (reaction) zone, quenching the carbon black reaction, and collecting the carbon black product. Also discussed is a method for making a carbon black product having varying physical characteristics as a result of modifying reaction kinetics at any position of oil injection into the "zones of turbulence".

  • Patent number: 4358289
    Abstract: In a furnace system for producing carbon black, a primary quench fluid is injected into the combustion products from the furnace to produce effluent. The effluent is passed through a trim quench chamber containing a tubular member. The tubular member has an internal flow path therethrough and is positioned in the housing defining the quench chamber to form an outer flow path therebetween. Part of the effluent flowing through the quench chamber passes through the internal flow path while the remainder passes through the outer flow path. Quench liquid is introduced into the quench chamber for initial contact with substantially only the portion of the effluent passing through the internal flow path.

  • Patent number: 4351817
    Abstract: A carbon black reactor is comprised of a housing which defines a precombustion zone, a reaction zone and a quench zone which are in flow communication. Inlet means open into the precombustion zone or the reaction zone and is operable to introduce make hydrocarbon into the reactor. Also, inlet means open into the precombustion zone and is operable for the introduction of hot combustion gases into the precombustion zone. The make hydrocarbon is pyrolyzed by contact with the hot combustion gases as same flow along the reaction zone. After a predetermined time as determined by the length of flow along the reaction zone, the effluent produced by the pyrolysis of the make hydrocarbon by contact with the combustion gases is quenched to stop the reaction.
