STABLE ZEOLITE OF LOW UNIT CELL CONSTANT AND METHOD OF MAKING SAME |
| 摘要 |
2115370 9325477 PCTABS00028 Y-type zeolites with unit cell constants of less than 24.14 Å are prepared by improving the method of dealumination and aluminum ion exchange. Zeolites with such low unit cell constants have not been known previously.
