RARE-EARTH CONTAINED Y TYPE MOLECULAR SIEVE AND PREPARATION METHOD THEREOF |
摘要 |
<p>The present invention provides a rare earth-containing Y zeolite and a preparation process thereof, said rare earth-containing Y zeolite has a rare earth content as rare earth oxide of 10-25wt%, a unit cell size of 2.440-2.472nm, a crystallinity of 35-65%, a Si/Al atom ratio in the skeleton of 2.5-5.0; and a product of the ratio of the strength I 1 of the peak at 2¸=11.8±0.1° to the strength I 2 of the peak at 2¸=12.3±0.1° in the X-ray diffraction spectrogram of the zeolite and the weight percent of rare earth as rare earth oxide in the zeolite of higher than 48.</p> |
