ABSTRACT:
Disclosed are methods for dehydrogenation of alkanes into alkenes in reactor systems of improved resistance to carburization under dehydrogenation conditions. The reactor walls are provided with a carburization and abrasion resistant protective layer by applying a metal plating, cladding or other coatings, such as painting, of a metal, such as Sb, As, Bi, Cu, Cr, Ga, Ge, In, Pb, Se, Te, Sn, particularly tin as a stannide layer, for forming a carburation resistant protective layer to a thickness of about 0.5 to 15 mils, effective to isolate the steel portion from hydrocarbons during the dehydrogenation process while avoiding any substantial liquid metal embrittlement. The protective layer is formed anchored to the steel portion through an intermediate carbide-rich bonding layer.
