一种Y-Beta复合分子筛的快速合成方法
摘要：
本发明涉及一种Y-Beta复合分子筛的快速合成方法，该复合分子筛的制备方法包括：第一步，将氢氧化钠和四乙基溴化铵溶于一定的去离子水中，然后选择性加入氨水；第二步，将上述溶液置于40℃-100℃的水浴锅中，然后将Y型分子筛粉末加入到第一步的溶液中，搅拌成均匀的混合物；第三步，将硅源缓慢的加入到第二步的水浴溶液中，密闭搅拌2-4小时，得到均匀的反应混合物凝胶体系。反应混合物凝胶体系混合物的摩尔比为：1.16-1.18Na2O∶6.10-6.34SiO2∶1.80-1.92TEABr∶0-4.0NH4OH∶Al2O3∶105-109H2O，反应混合物在密闭条件下于135℃-145℃下晶化72-90小时，得到Y-Beta复合分子筛。
摘要（英）：

The invention relates to a method for compositing compound zeolite Y-Beta quickly. The method for preparing compound zeolite comprises the steps as follows: step 1, dissolving sodium hydroxide and tetraethylammonium bromide in certain deionized water and adding ammonia water selectively; step 2, placing the solution in a water bath with the temperature of 40 DEG C to 100 DEG C, adding Y type zeolite powder in the solution of the step 2, and mixing to form uniform mixture; and step 3, adding silica source in the water bath solution of the step 2 slowly and mixing for 2 to 4 hours under an airtight condition to obtain a uniform reaction mixture gel system, wherein the molar ratio of the uniform reaction mixture gel system is 1.16 to 1.18 of Na2O : 6.10 to 6.34 of SiO2 : 1.80 to 1.92 of TEABr : 0 to 4.0 of NH4OH : Al2O3 : 105 to 109 of H2O. Afterwards, the reaction mixture is crystallized under the temperature of 135 DEG C to 145 DGC C for 72 to 90 hours under an airtight condition to obtain the compound zeolite Y-Beta.
