ZEOLITE CATALYST AND METHOD OF CONVERTING HYDROCARBONS USING THE SAME.

摘要

THE PRESENT INVENTION PROVIDES A CATALYST TO CONVERT HYDROCARBONS, WHICH COMPRISES A ZEOLITE CONTAINING SUBSTANTIALLY NO PROTON AND HAVING AN INTERMEDIATE PORE DIAMETER, A MOLAR RATIO OF SIO2 TO A12O3 OF AT LEAST 20 AND ONE OR MORE METALS BELONGING TO GROUP IB OF THE PERIODIC TABLE. FURTHER, THE PRESENT INVENTION PROVIDES A METHOD TO CATALYTICALLY CONVERT HYDROCARBONS BY USING THE ABOVE CATALYST. BY MEANS OF THE PRESENT INVENTION, THERE CAN BE PROVIDED A STABLE CATALYST FOR CONVERSION OF HYDROCARBONS, WHICH IS CAPABLE OF OBTAINING OLEFINS CONTAINING ETHYLENE AS A MAIN COMPONENT AND MONOCYCLIC AROMATIC HYDROCARBONS WITH GOOD BALANCE AND A HIGH YIELD, AND WHICH IS HARDLY DETERIORATED BY STEAM HAVING A HIGH TEMPERATURE.
