SBA-15吸附脱除油品中的碱性氮化物

以SBA -15介孔分子筛为吸附剂，喹啉十二烷溶液作为模拟油，在间歇式反应釜中，用静态吸附法对SBA -15的吸附脱氮性能进行了评价，并考察了吸附温度，吸附时间，剂/油质量比对模拟油脱氮率的影响，也考察了SBA-15经焙烧再生后的重复使用性能。结果表明，SBA-15介孔分子筛具有较强的吸附脱氮能力，吸附脱氮的最佳工艺条件为温度293K，吸附时间30 min，剂/油比为0.03， 在此条件下模拟油的脱氮率达到69.4 %，SBA-15经多次再生，其对模拟油吸附的脱氮率仍在66%以上。

Adsorption of Basic Nitrogen Compounds From Oil by SBA-15 Zeolite

The adsorption tests of quinoline in dodecane solution by SBA-15 mesoporous zeolite were conducted in batch scale reactor. The influences of adsorption temperature, adsorption time and the ratio of adsorbent to oil on the denitrogenation rate were investigated. Furthermore, the reusability of SBA-15 adsorbent regenerated by roasting process was tested. The results showed that SBA-15 mesoporous conditions had better adsorptive ability to the basic nitrogen compounds, and the optimum adsorption conditions were the adsorption temperature of 293 K, the adsorption to oil ratio of 0.03 and adsorption time of 30 min, under which the denitrogenation rate was 69.4%. After multiple regeneration of SBA-15 adsorbent, the denitrogenation rate was still more than 66%.
