Abstract:
A method comprising the steps of:(a) contacting a tube of a cracking furnace with a composition having C5+ production enhancing properties containing tetrabutyltin and hexamethyldisiloxane to thereby provide a treated tube wherein said composition has a molar ratio of tetrabutyltin to hexamethyldisiloxane in the range of from about 1:10 to about 10:1; (b) charging a saturated hydrocarbon stream to said treated cracking tube operated under suitable conditions for cracking said saturated hydrocarbon stream; (c) producing a product stream having a concentration of hydrocarbon compounds having at least five carbon atoms greater than that of said product stream when the treatment of step (a) is not performed; and (d) recovering at least a portion of said concentration of hydrocarbon compounds having at least five carbon atoms.
