Abstract:
1. A method of preparing a hydrocarbon steam cracking catalyst comprising the steps of: (a) preparing an aqueous solution by mixing Cr containing compound and Zr containing compound or Cr—Zr containing compound with water; (b) preparing a slurry by co-precipitation after adding ammonia water to the aqueous solution; (c) heat-refluxing or hydrothermal-treating the slurry; (d) preparing an oxide catalyst by filtering, drying and calcining the slurry, wherein the oxide catalyst is represented by CrZr (e) preparing a composite catalyst by sintering a mixture of a powder of the oxide catalyst and a carrier powder; (f) molding the composite catalyst; and (g) sintering the molded composite catalyst.
