摘要：考察了几种分子筛催化剂对芳烃中微量烯烃的脱除效果。结果表明,介孔材料催化剂的脱烯烃效果较好。对介孔材料催化剂进行酸性调变改性,并对改性前后的介孔材料催化剂进行脱烯烃效果对比及XRD和IR分析。结果表明,改性后,介孔材料催化剂表面的L酸浓度显著增大,提高了芳烃中烯烃杂质的脱除效果,并延长了催化剂的使用寿命。
Deep removal of olefins in aromatic hydrocarbons was investigated using various molecular sieve catalysts, and mesoporous material catalyst was found to be the best one among them. The mesoporous material was modified to adjust its acidity, and said materials prior and post to modification was characterized by XRD and FT-IR. Test results showed that the Lewis acidity of mesoporous material post to modification increased significantly, thus its catalytic activity of removing olefins in aromatic hydrocarbons was enhanced and service life was prolonged.
