Samples X #21-X #30 were prepared using silica-alumina molecular sieves having EMT topology as seed crystals, of which silica-alumina ratios were 10, 8, 8.5, 7, 7, 8, 21, 7, 8, 22 respectively, and which were purchased from Henan Huanyu Molecular Sieve Co., Ltd.

Comparative Example 1 Preparation of Comparative Samples V #1-V #30

[0274] The specific types of raw materials for preparing synthetic gel, molar ratio thereof, preparation process and crystallization conditions are the same as those of sample X #1 in Example 1, except than the seed crystal addition step is omitted. The specific types of raw materials, molar ratio thereof, crystallization conditions, and crystal structure of the product are shown in Table 2. The obtained samples are denoted as comparative samples V #1-V #30.

Example 3 Characterization and Analysis of Sample X #1-X #30 and Comparative Samples V #1-V #30

[0275] The phases of samples X #1-X #30 and comparative samples V #1-V #30 were analyzed by X-ray diffraction method.

[0276] The results show that each of the samples X #1-X #30 prepared in Examples 1 and 2 is Y molecular sieve with both high purity and high crystallinity. The XRD spectrum of sample X #1 as typical representative is shorn in FIG. 1, SEM image thereof is shown in FIG. 2, and Si NMR thereof is shown in FIG. 3. The XRD spectrum result of any one of samples X #2-X30 is close to FIG. 1. In other words, the diffraction peak positions and shapes are substantially identical. The relative peak intensity fluctuates within ±5% depending on the change of synthesis conditions, demonstrating that any of samples X #1-X #30 has the structural characteristics of Y zeolite and has no impurities. The silica-alumina ratio of any sample is much higher than that of conventional Y zeolite. The introduction of organic templating agent is the key to the synthesis of high-silica Y zeolite.

[0277] Each of V #1-V #30 as products in Table 2 is amorphous, and the XRD spectrum of the comparative sample V #1 as typical represenative is shown in FIG. 4. It can be seen that during the synthesis of high-silica Y zeolite, in addition to the organic templating agent, the introduction of seed crystal is also necessary.

Example 4 Preparation of Sample X1

[0278] Preparation of synthetic gel: 0.7 g sodium aluminate (Al.sub.2O.sub.3:48.3 wt %, Na.sub.2O: 36.3 wt %, China National Pharmaceutical (Group) Shanghai Chemical Reagent Company), 0.20 g sodium hydroxide, 13.74 g N,N-dimethyl-3,5-dipropylpiperidine hydroxide (25 wt %.) were dissolved in 1.82 g deionized water and stirred until to be clear. 13.3 g silica sol (SiO.sub.2:30 wt % Shenyang Chemical Co., Ltd.) was added therein dropwise and stirred for 2 hours. Then 0.4 g Y zeolite as seed crystal with silica-alumina ratio of 3 was added, and stirring was continued for 2 hours.

[0279] Synthesis at high-silica Y zeolite: The synthesis gel was transferred into a stainless-steel reactor, and was subject to rotational crystallization at 130° C. for 5 days. After the crystallization was completed, the obtained solid was separated from liquid, washed to be neutrality, then dried at 100° C. for 12 hours. The obtained sample was denoted as sample X1.

[0280] X-ray diffraction (XRD) spectrum of sample X1 is shown in FIG. 5. demonstrating that the sample X1 is molecular sieve having FAU framework structure. Scanning electron microscope (SEM) image thereof is shown in FIG. 6, demonstrating that the particles of sample X1 are small pieces with a size ranging from 50 nm to 200 nm. .sup.29Si MAS NMR spectrum thereof is shown in FIG. 7. The fitting calculation shows that the silica-alumina ratio in the framework is consistent with the calculation results conducted by XRF. According to the XRF and .sup.13C MAS NMR normalization analysis, the element constitution of sample X1 is 0.07Na.0.07R.sup.1.(SiO.sub.0.86Al.sub.0.14)O.sub.2, where R.sup.1 is N,N-dimethyl-3,5-dipropylpiperidine hydroxide.

Example 5: Preparation of Samples

[0281] The preparation process of any one of sample X2-X30 is the same as that of Example 4. The raw materials for preparing samples X2-X30, molar ratio thereof, addition amount of seed crystal (weight ratio of seed crystal to SiO.sub.2 in gel), crystallization conditions, crystal structure, silica-alumina ratio (the silica-alumina radio of the obtained product is measured by X-ray fluorescence analyzer (XRF)) and the product constitution are shown in Table 3.

[0282] Samples X1-X20 were prepared using silica-alumina to molecular sieves having FAU topology as seed crystals, of which silica-alumina ratios were 3, 2.8, 3.5, 40, 5, 6.6, 6, 6, 7, 92, 10, 3.5, 4. 6, 8, 4. 35, 12, 20 respectively, and which were purchased from Zibo Runxin Chemical Technology Co., Ltd. Samples X21-X30 were prepared using silica-alumina molecular sieves having EMT topology as seed crystals, of which silica-alumina ratios were 7, 7, 8.5, 7, 8, 10, 21, 32.8 and 7 respectively, and which were purchased from Henan Purchased by Hnamyu Molecular Steve Co., Ltd.

Comparative Example 2: Preparation of Comparative Samples V1-V30

[0283] The preparation process of any one of samples V1-V30 is the same as that of Example 4, except that there is no seed crystal addition step. Types of raw materials, molar ratio thereof, crystallization conditions, and crystal structure of samples V1-V30 are shown in Table 4. The samples obtained are denoted as comparative samples V1-V30.

Example 6: Characterization and Analysis of Sample X1-X30 and Comparative Samples V1-V30

[0284] The phases of sample X1-X30 and comparative samples V1-V30 were analyzed by X-ray diffraction method.

[0285] The results show that each of the samples X1-X30 prepared in Examples 4 and 5 is Y molecular sieve with both high purity and high crystallinity. The XRD spectrum of sample X1 as typical representative is shown in FIG. 5. SEM image thereof is shown in FIG. 6, and Si NWR thereof is shown in FIG. 7. The XRD spectrum result of any one of samples X2-X30 is close to FIG. 1. In other words, the diffraction peak positions and shapes are substantially identical. The relative peak intensity fluctuates within ±5% depending on the change of synthesis conditions, demonstrating that any of samples X1-X30 has the structural characteristics of Y zeolite and has no impurities. The silica-alumina ratio of any sample is much higher than that of conventional Y zeolite. It can be seen that during the synthesis of the high-silica Y molecular sieve according to the present application the introduction of nitrogen-containing heterocyclic templating agent is the key to the synthesis of the high-silica Y molecular sieve according to the present application.

[0286] In Table 4, each of the comparative samples V1-V30 is amorphous, and a XRD spectrum of the comparative sample V1 as typical representative is shown in FIG. 4. It can be seen that during the synthesis of high-silica Y zeolite, in addition to the introduction of nitrogen-containing heterocyclic templating agent, the introduction of seed crystal is also necessary.

The XRD spectrum of sample Y #1 as typical representative is shown in FIG. 9. SEM image thereof is shown in FIG. 10, and Si NMR thereof is shown in FIG. 11. The XRD spectrum result of any one of samples Y #2-Y #30 is close to FIG. 9. In other words, the diffraction peak positions and shapes are substantially identical. The relative peak intensity fluctuates within ±5% depending on the change of synthesis conditions, demonstrating that any of samples Y #1-Y #30 has the structural characteristics of Y zeolite and has no impurities.

Then the obtained solid was separated from liquid, washed to be neutrality, and dried at 100° C. for 12 hours. The obtained sample was denoted as sale Y1.

[0300] X-ray diffraction (XRD) spectrum of sample Y1 is shown in FIG. 14, demonstrating that the sample Y1 is molecular sieve having FAU framework structure. Scanning electron microscope (SEM) image thereof is shown in FIG. 15. demonstrating that the particles of sample Y1 are small pieces with a size ranging from 50 nm to 200 nm. .sup.29Si MAS NMR spectrum thereof is shown in FIG. 16. The fitting calculation shows that the silica-alumina ratio in the framework is consistent with the calculations results conducted by XRF. According to the XRF and .sup.13C MAS NMR normalization analysis, the element constitution of sample Y1 is 0.07Na.0.02R1.sup.2.0.05R2.sup.1 (Si.sub.0.85Al.sub.0.14)O.sub.2, wherein, R1.sup.2 is a tetraethylammonium hydroxide, R2.sup.1 is N,N-dimethyl-3,5-dipropyl-piperidine hydroxide.

[0301] The preparation process of any one of samples Y2-Y30 is the same as that of Example 10. The raw materials for preparing samples Y2-Y30, molar ratio thereof, crystallization conditions, crystal structure, and silica-alumina ratio (the silica-alumina ratio of the obtained product is measured by X-ray fluorescence analyzer (XRF) are shown in Table 3. Aging temperature and time for preparing directing agent, addition amount of directing agent and sample constitution are shown in Table 10.

Comparative Example 5: Preparation of Comparative Samples S1-S30

[0302] The specific preparation process is the same as that in the preparation of sample Y1 in Example 10, except that there is no directing agent preparation step, and there is not addition of directing agent in the subsequent gel synthesis step. The types of raw materials, molar ratio thereof, crystallization conditions and product structure of the prepared products are shown in Table 11. The samples obtained are denoted as comparative samples S1-S30.

Comparative Example 6: Preparation of Comparative Samples T1-T30

[0303] The specific preparation process is the same as that m to preparation of sample Y1 in Example 10, except that after the batching step of the directing agent is completed, only stirring at room temperature for 2 hours without aging was performed. Types of raw materials, molar ratio thereof, crystallization conditions, addition amount of directing agent and product structure of each synthesized product are shown in Table 12. The samples obtained are denoted as comparative samples T1-T30.

Example 12: Characterization and Analysis of Samples Y1-Y30 and Comparative Samples S1-S30 and T1-T30

The XRD spectrum of sample Y1 as typical representative is shown in FIG. 14. SEM image thereof is shown in FIG. 15, and Si NMR thereof is shown in FIG. 16. The XRD spectrum result of my one of samples Y2-Y30 is close to FIG. 14. In other words, the diffraction peak positions and shapes are substantially identical. The relative peak intensity fluctuates within ±5% depending on the change of synthesis conditions, demonstrating that any of samples Y1-Y30 has the structural characteristics of Y zeolite and has no impurities.

[0306] In tables 9 and 10, the comparative samples S1-S30 and the comparative samples T1-T30 are all amorphous. As a typical representative, the XRD spectra of the comparative sample S1 and the comparative sample T1 are shown in FIG. 17 and FIG. 18, respectively.
