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.

Method for improving the yield of heavy hydrocarbons in a thermal cracking process

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 of promoting the decomposition of silicon compounds in a process

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.
