摘要：Deep removal of trace olefins from aromatics using mesoporous materials and modified mesoporous materials was studied with regard to the removal of trace olefins from aromatic hydrocarbons. The mesoporous materials and the modified mesoporous molecular sieve materials were characterized by X-ray diffraction and Fourier transform infrared (FT-IR) spectroscopy. Under the commercial sidestream test, the effects of four types of mesoporous materials, with regard to the removal of olefins from the aromatics, were evaluated. The result showed that the mesoporous materials that had Surface areas larger than 300 m(2)/g and modified with AlCl3 were best, with regard to the effect on the removal of olefins from aromatics. The FT-IR results showed that the modifier could increase the concentration of weak Lewis acid of mesoporous materials and obviously enhance the effect of removing olefins and prolonging the reaction time.
