OXIDE CATALYST AND PHOSPHORIC OXIDE CATALYST FOR HYDROCARBON STEAM CRACKING, METHOD FOR PREPARING THE SAME AND METHOD FOR PREPARING OLEFIN BY USING THE SAME

摘要

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.
