Abstract
A thermal cracking process is provided which comprises contacting a thermal cracking furnace with a fluid stream which comprises steam and a polysulfide such as di-t-nonylpolysulfide under a condition sufficient to effect the suppression of the formation of carbon monoxide and thereafter introducing a steam fluid containing a saturated hydrocarbon such as ethane and a polysulfide such as di-t-nonylpolysulfide under a condition sufficient to convert the saturated hydrocarbon to an olefinic compound such as ethylene.
