Abstract
Advanced zinc-based sorbents, ZA, for Hot Gas Desulfurization (HGD) process in Integrated Gasification Combined Cycle (IGCC) systems were formulated with $Al_2$O$_3$ as support to enhance the reactivity and their reactive characteristics was also investigated in this study. Changes in the physical and chemical properties of the sorbents based on both the mole ratios of ZnO/Al$_2$O$_3$ and the calcination temperatures were examined by a XRD. The results obtained in our desulfurization-regeneration cycle tests demonstrated that degradation of sorbents due to the heat generation could be improved through the optimization of the $Al_2$O$_3$ contents and of the calcination temperatures. From the durability study it is concluded that the prepared ZA sorbents with additives have the desirable features for HGD.
