Preparation of TS-1 by dynamic method and study on the performance of thiophene sulfur removal

Using TPAOH as the template, TEOS as the silicon source and TBOT as the titanium source, the as-prepared samples utilizing a dynamic crystallizating kettle possessed regular morphology and the average particle size of 600 nm. By modulating the dosage of TBOT, and then changing the molar ratio of titanium to silicon in the initial synthesis solution, the effect of silicon to titanium ratio on TS-1 molecular sieve was investigated. TS-1 zeolite properties were characterized by means of SEM, TEM, XRD, FT-IR, UV-vis, XPS, N₂ adsorption and desorption technology. Finally, using a simulated system of thiophene n-octane dissolved in octane, the catalytic oxidative desulfurization performance of TS-1 zeolite was investigated.
