ADDITIVE FOR REDUCING COKING AND/OR CARBON MONOXIDE IN CRACKING REACTORS AND HEAT EXCHANGERS AND USE OF SAME

摘要

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 disulfide (DEDS) or dipropyl disulfide(s) (DPDS) or dibutyl disulfide(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.
