  • Composition and method for inhibiting coke formation and deposition during pyrolytic hydrocarbon processing
    Patent number: 5330970
    Abstract: Methods and compositions are provided for inhibiting the formation and deposition of pyrolytic coke on metal surfaces in contact with a hydrocarbon feedstock undergoing pyrolytic processing. Coke inhibition is achieved by adding a coke inhibiting amount of a combination of a boron compound and a dihydroxybenzene compound.
    Type: Grant
    Filed: April 1, 1992
    Date of Patent: July 19, 1994
    Assignee: Betz Laboratories, Inc.
    Inventors: Dwight K. Reid, Daniel E. Fields
  • Methods for retarding coke formation during pyrolytic hydrocarbon processing
    Patent number: 5221462
    Abstract: The present disclosure is directed to methods for controlling undesirable coke formation and deposition on structural surfaces which is commonly encountered during the high temperature processing of hydrocarbons. Coke formation can be inhibited by adding an effective amount of a dihydroxybenzene to the system suffering from coke formation.
    Type: Grant

  • Use of boron containing compounds and dihydroxybenzenes to reduce coking in coker furnaces
    Patent number: 5093032
    Abstract: The present disclosure is directed to a composition and methods for controlling undesirable coke formation and deposition commonly encountered during the high temperature processing of hydrocarbons. Coke formation can be inhibited by adding a sufficient amount of a combination of a boron compound and a dihydroxybenzene.
