| titleOfInvention | Hydrocarbon Pyrolysis Method |
| abstract | Disclosed is a method of pyrolysis by a pyrolysis apparatus comprising a tubular heating furnace comprising a radiating portion and a convection portion for pyrolyzing a hydrocarbon raw material supplied with steam according to the present invention. At this time, part or all of the hydrocarbon pyrolysis catalyst is filled in the tube located in the radiant portion of the tubular heating furnace, and the hydrocarbon pyrolysis catalyst is an oxide catalyst represented by CrZrjAkOx (0.5 ≦ j ≦ 120, 0 ≦ k ≦ 50 , A is a transition metal, and x is Cr, a number satisfying the condition according to the valence of Zr and A and the value of j and k). The hydrocarbon pyrolysis method according to the present invention improves the yield and selectivity of the olefin when the olefin is prepared by steam pyrolysis of the hydrocarbon, and has excellent heat transfer efficiency, thus reducing the fuel used, and the amount of coke deposited on the inner wall of the pipe. It is possible to extend the period of the decoking operation. |
