Method and reactor containing perovskite for cracking hydrocarbon and method for coating the reactor

Abstract:

A reactor has an inner surface accessible to the hydrocarbon and comprising a sintered product of at least one of cerium oxide, zinc oxide, tin oxide, zirconium oxide, boehmite and silicon dioxide, and a perovskite material of formula: A.sub.aB.sub.bC.sub.cD.sub.dO.sub.3-.delta.. 0<a<1.2, G.ltoreq.b.ltoreq.1.2, 0.9<a+b.ltoreq.1.2, O<c<1.2, 0.ltoreq.d.ltoreq.1.2, 0.9<c+d.ltoreq.1.2, -0.5<.delta.<0.5. A is selected from calcium, strontium, barium, and any combination thereof. B is selected from lithium, sodium, potassium, rubidium, and any combination thereof. C is selected from cerium, zirconium, antimony, praseodymium, titanium, chromium, manganese, ferrum, cobalt, nickel, gallium, tin, terbium and any combination thereof. D is selected from lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetiura, scandium, titanium, vanadium, chromium, manganese, ferrum, cobalt, nickel, copper, zinc, yttrium, zirconium, niobium, molybdenum, technetium, ruthenium, rhodium, palladium, silver, cadmium, hafnium, tantalum, tungsten, rhenium, osmium, iridium, platinum, gold, gallium, indium, tin, antimony and any combination thereof.
