Abstract:
The present invention relates to an oxide catalyst and a phosphoric oxide catalyst for hydrocarbon steam cracking, method for preparing the same and a method for preparing olefin by using the same. More precisely, the present invention relates to an oxide catalyst for hydrocarbon steam cracking represented by formula 1 and a phosphoric oxide catalyst for hydrocarbon steam cracking represented by formula 3 which would be used for the production of olefin such as ethylene and propylene by hydrocarbon steam cracking, and a method for preparing the same. The present invention provides an oxide catalyst and a phosphoric oxide catalyst for hydrocarbon steam cracking that has excellent thermo-stability at high temperature and improved olefin yield. CrZrjAkOx [Formula 1] CrZrjAkPlOx [Formula 3] Wherein, j, k, l and x are as indicated in the description.
