DEHYDROGENATION PROCESSES AND EQUIPMENT THEREFOR

摘要

A method for dehydrogenation comprising: (i) providing a carburization and abrasion resistant protective layer to a steel portion of a dehydrogenation reactor system by (a) applying to the steel portion a meta l plating, cladding or other coating of a metal effective for forming a carburization resistant protective layer to a thickness effective to isolate the steel portion from hydrocarbons during operation while avoiding any substantial liquid metal embrittlement, and (b) forming t he protective layer, anchored to the steel portion through an intermediate carbide-rich bonding layer, (ii) catalytically dehydrogenating a dehydrogenatable hydrocarbon.
