A method for cracking hydrocarbon, comprises: providing steam and hydrocarbon; and feeding steam and hydrocarbon into a reactor accessible to hydrocarbon and comprising a perovskite material of formula A a B b C c D d O 3-δ , wherein 0<a<1.2, 0≦b≦1.2, 0.9<a+b≦1.2, 0<c<1.2, 0≦d≦1.2, 0.9<c+d≦1.2, −0.5<δ<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; and D is selected from lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, ebium, thulium, ytterbium, lutetium, 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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of inhibiting coke deposit formation in a hydrocarbon cracking reactor having an inner surface accessible to said hydrocarbon and wherein a hydrocarbon comprising ethane is cracked in the presence of steam at a temperature of about 480° C. to about 870° C. to form ethylene, said inner surface comprising a perovskite material selected from the group consisting of BaZr 0.3 Ce 0.7 O 3 , BaZr 0.7 Ce 0.3 O 3 , and BaCe 0.5 Zr 0.5 O 3 and combinatio…
