| 摘 要： | 通过对Y分子筛进行铵交换，获得了分子筛孔道相似、酸密度在2.87~12.99 mmol/g范围内的一系列分子筛。在控制变量的前提下，考察了这一系列分子筛在异丁烷-丁烯烷基化反应中的催化性能，研究了分子筛酸密度对其催化烷基化反应活性的影响规律。结果表明，分子筛总酸密度越大，其相对氢转移活性越高，催化烷基化反应单程寿命越长，越有利于烷基化目标产物的生成。

| Abstract: | A series of Y zeolites with similar pore structures and different acid densities in the range of 2.87 to 12.99 mmol/g were prepared by exchanging Na+ ion with ammonium salts. The effect of acid density on their catalytic performance was studied. The results show that high hydride activity and long single-pass catalyst life are due to the high acid density, which is beneficial for high selectivity of target products. |
