Method for preparing copper exchanged type x zeolite |
| abstract |
COPPER-EXCHANGED TYPE X ZEOLITE IS PREPARED BY IONEXCHANGING A SODIUM TYPE X ZEOLITE WITH A COPPER SALT SOLUTION, HEATING THE ZEOLITE TO EFFECT AT LEAST PARTIAL DEHYDRATION OF THE ZEOLITE, CONTACTING THE ZEOLITE WITH A MIXTURE COMPRISING A CUPROUS SALT AND A HYDROCARBON CAPABLE OF FORMING A SOLUBLE COMPLEX WITH THE CUPROUS SALT AND PASSING THE PORE OPENINGS OF THE ZEOLITE, SUBJECTING THE ZEOLITE TO REDUCING CONDITIONS TO EFFECT AT LEAST A PARTIAL REDUCTION OF THE CUPRIC IONS TO CUPROUS IONS, AND HYDRATING THE ZEOLITE TO A DESIRED WATER CONTENT. THE PRODUCT IS PARTICULARLY USEFUL IN THE SELECTIVE SEPARATION OF OLEFINIC HYDROCARBONS FROM SATURATED HYDROCARBONS IN THE PRESENCE OF CONTAMINANT AROMATIC HYDROCARBONS. |
