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.

Abstract: A liquid tin-containing antifoulant composition is injected into a metal-walled thermal cracking reactor tube, concurrently with the injection of a gaseous stream (preferably a steam-diluted C₂-C₄ alkane stream), through a nozzle of an injection quill which is positioned in the center region of the reactor tube substantially parallel to the flow of the gaseous stream.A liquid tin-containing antifoulant is injected into a metal-walled thermal cracking reactor tube through a nozzle of an injection quill at a temperature of about 1000-1300°F while a gaseous stream (preferably a steam-diluted C₂-C₄ alkane stream) flows through the reactor tube, followed by raising the temperature to about 1400-1800°F. Preferably, the metal walls of the reactor tube are treated with steam after the antifoulant injection at about 1000-1300°F but before the antifoulant injection at about 1400-1800°F.

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.

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.
