Synthesis, Characterization and Catalytic Performance of Titanium-Modified TUD-1 in the Hydrodesulfurization of FCC Diesel

Abstract

Highly active titanium modified 3D mesoporous material Ti-TUD-1 with different Si/Ti molar ratios (10, 25, 50 and 100) were synthesized using TEA as a template and TEAOH as an auxiliary template. The Ti-TUD-1 materials were characterized by means of XRD, TEM and UV-vis DRS. The results showed that Ti was successfully incorporated in the framework of TUD-1 by forming Ti-O-Si bonds. The catalytic activities were tested in a high pressure micro reactor using FCC diesel and the results showed that the HDS efficiency of Ti modified TUD-1(Si/Ti=50) was better than TUD-1, as high as 98.15%.
