    摘要： An apparatus is provided for producing a carbon black with a tint residual below -6. The apparatus entail introducing feedstock axially and generating a hot combustion gas vortex in a cylindrical precombustion section of a tubular carbon black reactor, producing a first mixture of feedstock and combustion gases, passing this mixture through an abruptly restricted passage axially connected to the precombustion section, abruptly expanding the first mixture into a frustoconical venturi converging section of the reactor with mixing of this first mixture with an additional flow of combustion gas at the exit of the converging section with the combustion gas entering the converging section in opposite, radial flow thereby forming a second mixture which is admitted into a reaction section of the carbon black reactor.

    摘要： Carbon black is pelleted by combining loose carbon black with an aqueous pelleting liquid and agitating the mixture. Additional loose carbon black is added in a series of increments, followed by additional aqueous pelleting liquid containing an additive such as ammonium lignin sulfonate. The process produces layered pellets having a hardened outer shell. In another embodiment, an oil is added following the incremental addition of the loose carbon black in order to produce pellets which have a dust-free surface.

    摘要： A carbon black reactor with axial hydrocarbon feed and having an axial zone with triangular cross-section, a wider vortex section for generation of a combustion gas vortex, a reaction section and having essentially tubular shape is useful for the production of high tint and high structure carbon black. In a process for the production of carbon black, hydrocarbon feed is axially introduced into the reactor and contacted with a vortex of hot combustion gases.

    摘要： Carbon black is produced in a generally cylindrical reactor in which a hydrocarbon feed oil is introduced at one end generally along the axis of the reactor. A gaseous fuel and oxygen are introduced in directions generally parallel to the axis of the reactor to surround the feed oil. Inert gases are introduced into the reactor to surround the central core. Properties of the carbon black can be regulated by introducing the oxygen at a relatively high velocity and adjusting the rate at which the inert gases are introduced.
