    摘要: 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.

    摘要: The formation of carbon on metals exposed to hydrocarbons in a thermal cracking process is reduced by contacting such metals with an antifoulant selected from the group consisting of a combination of tin and copper, a combination of antimony and copper and a combination of tin, antimony and copper.
