  • Method for improving the yield of heavy hydrocarbons in a thermal cracking process
    Patent number: 6464858
    Abstract: The incremental yield of hydrocarbons having five or more carbon atoms in a cracked product from a thermal cracking process is increased by contacting or treating the tubes of a thermal cracking furnace with a composition comprising tin and silicon.
    Type: Grant
    Filed: August 25, 1994
    Date of Patent: October 15, 2002
    Assignee: Phillips Petroleum Company
    Inventors: Ronald E. Brown, Larry E. Reed, James P. Degraffenried, Timothy P. Murtha, Gil J. Greenwood, Timothy P. Harper, Mark D. Scharre
  • Method of promoting the decomposition of silicon compounds in a process for depositing silicon upon a metal surface
    Patent number: 6056870
    Abstract: For a given percentage decomposition, the decomposition temperature of an organosilicon compound is reduced by admixing with the organosilicon compound a decomposition promoting organotin compound. The amount of decomposition promoting organotin compound admixed with the organosilicon compound is sufficient to effectively lower the decomposition temperature of the organosilicon required for a given percentage decomposition.

  • Method for treating the radiant tubes of a fired heater in a thermal cracking process
    Patent number: 5656150
    Abstract: A novel method for treating the radiant tubes of a fired pyrolysis heater with an antifoulant composition for inhibiting the formation and deposition of coke thereon. Such novel method includes introducing the antifoulant into the crossover conduit between the convection tubes and radiant tubes of the fired pyrolysis heater.

  • Method for providing a tube having coke formation and carbon monoxide inhibiting properties when used for the thermal cracking of hydrocarbons
    Patent number: 5616236
    Abstract: The rate of formation of carbon on the surfaces of thermal cracking tubes and the production of carbon monoxide during thermal cracking of hydrocarbons are inhibited by the use of cracking tubes treated with an antifoulant, including tin compound, silicon compound and sulfur compounds in the presence of a reducing gas such as hydrogen. Additionally, the concentration of carbon monoxide in a pyrolytic cracking process product stream is reduced by the treatment of the thermal cracking tubes of such process with a reducing gas having a concentration of a sulfur compound.
