| 摘 要： | 本文对几种工业成型的5A脱蜡分子筛吸附水的性能进行了研究,并通过TPD方法测定NH_3、CO_2在分子筛样品上的脱附特性来考察它们的表面性质。结果表明,不同的5A分子筛样品对这些小分子的作用有差异,这些差异可能是由于样品的ca~(2+)离子交换度不同因而Ca~(2+)离子交换度不同因而Ca~(2-)离子在单胞中的布居不同所致。

| Abstract: | The effect of calciumions in 5A zeolites dewaxing processes was studied by the methods of adsorption and temperature-programmed desorption. It was found that the different sample of 5A zeolites has different effect on these small molecules, which could be caused by the different distribution of calciumions in the cell owing to its different exchange degree. |

| Keywords: | calciumions molecular sieves dewaxing by molecular sieve thermal desorption |
