Effect of a Support on the Properties of Zinc Oxide Based Sorbents.

We present the comparative analysis of three Zn-based sorbents for the process of sulphur removal from hot coal gas. The sorbents were prepared by a slurry impregnation of TiO, SiO and AlO, resulting in complex, multiphase materials, with the dominant phases of ZnTiO, ZnSiO and ZnAlO, respectively. We have analyzed the effect of supports on the phase composition, texture, reducibility and HS sorption.
