Abstract: Methyl tert-butyl ether (MTBE) is an important blending component of gasoline in China. Reducing the sulfur compounds contents in MTBE products can promote clean burning of gasoline and environmental protection. The MTBE products samples containing sulfur compounds were prepared with dimethyl disulfide (DMDS) and tert-butyl methyl sulfide (TBMS) using MTBE as solvents, respectively. The desulfurizer was composed of Pd/C, isopropanol, sodium hydroxide and deionized water. The Pd/C structure characteristics was characterized by N₂ adsorption isotherm, TEM and XRD. The feature of type Ⅰ isotherm confirmed that the existence of micropores in Pd/C catalyst and the BET surface area of Pd/C was 1 836 m²/g and the pore volume was 0.98 cm³/g, respectively. According to the adsorption isotherm, it could be concluded that most of the pores are micropores. The average particle size of Pd crystal particle shown in TEM images was about 3-5 nm and the crystal particles of Pd were distributed uniformly in activated carbon which could strengthen the catalytic efficiency and result in strong combination between Pd and activated carbon. Four typical diffraction peaks of Pd indicated the existence of the crystal faces (111), (200), (220) and (311) in the XRD patterns. By using batch reactor, the sulfur mass fraction in MTBE products could be reduced from 150 μg/g to below 10 μg/g in one hour at 50 ℃ and ultra-low sulfur MTBE products could be obtained. The desulfurization effect of desulfurizer was verified. The Pd/C was used as both the catalyst for producing hydrogen peroxide and the adsorbent removing sulfurs from MTBE products. It still had high catalytic and desulfurization performance after being eluted and regenerated.
