Abstract

The study was to investigate changes in the adsorption desulfurization performance of halloysite nanotubes(HNTs) with the introduction of metal components by incipient wetness impregnation. The samples were characterized by X-Ray diffractometer(XRD), adsorbed pyridine infrared spectroscopy(Py-IR) and N₂-sorption. The experimental results showed that three kinds of metal components were mainly presented as their oxides on HNTs, and Co₃O₄, NiO and CuO can all improve the adsorption desulfurization performance of HNTs, and the desulfurization rate of HNTs with 10% NiO increased the most, from 30.10% to 47.51%. Metal oxides improved the amount of Lewis acid on the surface of HNTs, and the adsorption desulfurization performance of HNTs increased with the change of the amount of Lewis acid. Therefore, the amount of Lewis acid on the surface of HNTs is an important factor affecting the adsorption desulfurization performance of HNTs.
