Treatment of aluminosilicate zeolites. |
| 摘要 |
<p>The degree of crystallinity of an aluminosilicate zeolite having a silica-to-alumina mole ratio less than 100 is enhanced by contacting the zeolite in the absence of an external source of aluminum with an aqueous fluoride solution having a pH of 3 to 7 under conditions sufficient to remove amorphous material from the zeolite.</p> |
