Abstract
The present invention concerns an additive for reducing the formation of coke and/or carbon monoxide in thermal hydrocarbon cracking units and/or of other organic compounds in heat exchangers. The additive according to the invention is essentially composed of diethyl disulphide (DEDS) or dipropyl disulphide(s) (DPDS) or dibutyl disulphide(s) (DBDS) and can be used on the metal walls of a cracking reactor and on the metal walls of a heat exchanger placed downstream from the cracking reactor, and during the process of cracking hydrocarbons and/or other organic compounds.
