  • Carbon black producing apparatus and method
    Patent number: 4230670
    Abstract: A carbon black reactor includes a housing which has a refractory lining defining an elongate chamber. The chamber is comprised of a plurality of compartments which include a combustion compartment, a reaction compartment and a quench compartment. An inlet means opens into the combustion compartment and is operable for introducing hot combustion gases into the combustion compartment. Another inlet means opens into the chamber and is operable for introducing a feedstock hydrocarbon into the chamber. Quench liquid inlet means opens into the quench compartment and is operable for introducing quench liquid into the quench compartment. The quench inlet means includes a plurality of tubular members extending into the quench compartment, each having spaced apart discharge openings along the length thereof.

  • Carbon black pelleter
    Patent number: 4136975
    Abstract: A carbon black pelleter is dislosed in which pins are affixed to a rotatable shaft and extend radially outwardly from the shaft in a plurality of helical flights. The pins are arranged such that upon rotation of the shaft the trace of a pin of a first helical flight overlaps the trace of a pin of a second azimuthally adjacent helical flight to produce narrow pellet size range.
    Type: Grant
    Filed: March 10, 1978
    Date of Patent: January 30, 1979

    Inventor: Glenn J. Forseth
  • Production of high structure soft carbon black
    Patent number: 3972986
    Abstract: A method of producing carbon black wherein a reaction mixture consisting essentially of hydrocarbon feed and gases introduced into a first zone are passed into a second zone having a diameter greater than the diameter of the first zone at a temperature proximate the pyrolytic decomposition temperature of the hydrocarbon feed.
