Abstract
The present invention relates to a thermal-cracking method of hydrocarbon using a hydrocarbon thermal-cracking apparatus including a tube type furnace having a radiation part for thermally cracking hydrocarbon feedstocks supplied together with steam and a convection part. A hydrocarbon thermal-cracking catalyst is packed in some or entire area of the tube placed in the radiation part of the tube type furnace, wherein the hydrocarbon thermal-cracking catalyst includes an oxide catalyst represented by CrZrAO(wherein, 0.5≦j≦120 and 0≦k≦50, A is a transition metal, and x is a number corresponding to the atomic values of Cr, Zr, and A and the numbers of j and k). Therefore, it is possible to improve yield and selectivity of olefin, reduce fuel consumption due to an excellent heat transfer efficiency and extend decoking interval by reduced production of coke deposited to an inside wall of a tube, in steam cracking of hydrocarbon for producing olefin.
