摘要： The present invention relates to a catalyst for hydrocarbon steam cracking for the production of light olefin, a preparation method of the catalyst and a preparation method of olefin by using the same. More precisely, the present invention relates to a composite catalyst prepared by mixing the oxide catalyst powder represented by CrZrjAkOx (0.5≦j≦120, 0≦k≦50, A is a transition metal, x is the number satisfying the condition according to valences of Cr, Zr and A, and values of j and k) and carrier powder and sintering thereof, a composite catalyst wherein the oxide catalyst is impregnated on a carrier, and a method of preparing light olefin such as ethylene and propylene by hydrocarbon steam cracking in the presence of the composite catalyst. The composite catalyst of the present invention has excellent thermal/mechanical stability in the cracking process, and has less inactivation rate by coke and significantly increases light olefin yield.

摘要： 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 CrZrjAkOx (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.
