Na Y分子筛合成体系中添加铝的络合剂 (乙二胺四乙酸、柠檬酸和醋酸 ) ,可有效地减小分子筛的晶粒尺寸及增加分子筛的晶化速度和 Si O2 /Al2 O3物质的量比 .在添加柠檬酸的合成体系中 ,考察了柠檬酸的添加量对 Na Y分子筛晶化行为的影响 .发现存在着一个最佳的柠檬酸的添加量范围 ,即 n(柠檬酸 )∶ n(氧化铝 )≤ 2∶ 1 ,在此范围内 ,Na Y的晶化速率和硅铝比较高 ,而晶粒尺寸较小 . The addition of aluminum complexing agents (ethylenediaminetetraacetic acid, citric acid and acetic acid) to NaY molecular sieve synthesis system can effectively reduce the grain size of the molecular sieve and increase the crystallization rate of the molecular sieve and the increase of Si O2 / Al 2 O 3 content The ratio of citric acid in the synthesis of the system to examine the amount of citric acid on the crystallization of YY zeolite crystallization behavior found that there is an optimum range of citric acid added that n (citric acid): n (alumina) ≤ 2: 1. Within this range, the crystallization rate of NaY is higher than that of SiAl and the grain size is smaller.
