SODIUM TOLERANT ZEOLITE CATALYSTS AND PROCESSES FOR MAKING THE SAME |
摘要 |
<p>This invention relates to a process of preparing a catalyst from zeolite having a relatively high content of sodium of 18.6 µg Na2O per zeolite surface area, or greater. The invention comprises adding yttrium compound to the zeolite, either prior to, during, or after its combination with precursors for catalyst matrix. This invention is suitable for preparing zeolite containing fluid cracking catalysts.</p> |
