摘　　要：研究一种陈化时间短、有效性较高的导向剂,并以现有的工业原材料通过水热合成法在较高温度、一定压力下制备NaY分子筛。结果表明,陈化时间对导向剂的有效性具有显著影响,(16~24)h为最佳陈化时间。采用最佳陈化时间导向剂、在晶化温度(110~115)℃条件下合成的NaY分子筛相对结晶度可达到91%。In this paper,a kind of guide agent with short aging time and high efficiency was studied,and NaY zeolite was prepared by hydrothermal synthesis from existing industrial raw materials under high temperatur e and certain pressure.The results show that the aging time has a significant effect on the effectiveness of the directing agent,and the optimum aging time is(16-24)h.The relative crystallinity of NaY molecular sieve can reach 91%under the condition of(110-115)℃crystallization temperature.
