Hydrocarbon cracking process in which a protective layer for a steel portion of the reactor is used

摘要

There is provided a method of thermal hydrocarbon cracking, comprising the step of thermally cracking a hydrocarbon feed in a cracking furnace comprising: a steel portion having a Group VIB metal protective layer; a carbide-rich bonding layer anchoring said steel portion to said protective layer; a material that fills or seals a crack in said protective layer; and wherein said protective layer has a thickness sufficient to isolate said steel portion from hydrocarbons upon said thermal hydrocarbon cracking.
