摘要: 用NaY沸石制备了负载二元金属Ni和Ce的NiCeY燃料油脱硫吸附剂，并通过静态吸附实验考察了NiCeY沸石对模拟燃油中二苯并噻吩（DBT）的吸附性能。结果表明，在正辛烷/DBT体系中，NiCeY 对DBT的吸附平衡时间为2 h；剂油比对脱硫率有明显影响，剂油比为0.1 g/mL时脱硫率达100%。在正辛烷/DBT/环己烯体系中，吸附剂对DBT吸附量的大小顺序为：NaY＜NiY＜CeY
- NiCeY沸石 /
- 二苯并噻吩 /
- 脱硫吸附
Abstract: The NiCeY zeolite adsorbent，for desulfurization of fuel oil，was prepared by NaY zeolites loaded with Ni and Ce ions simultaneously. The adsorption properties of NiCeY for dibenzothiophene (DBT) were studied with a batch method in a model fuel. Results reveal that it takes two hours for NiCeY to absorb DBT at a balanced level; the removal of DBT was obviously influenced by the absorbent/oil ratio, when the absorbent/oil ratio was increased to 0.1 g/mL, the removal efficiency of DBT was increased to 100 percent. In the system of noctane/DBT/cyclohexene, the absorption capacities of different absorbents to DBT are show as (orderly): NaY＜NiY＜CeY＜NiCeY. The sulfur selective adsorption capacity of NiCeY is the highest of the four, meaning that NiCeY is more effective in desulfurization of fuel oil in practical application.
