Summary:The preparation and performance of some oxides and mixed oxides supported sorbents by different ways for high temperature desulfurization of fuel gases were studied. The results obtained showed that the preparation method has a strong influence on the spatial distribution of the chemical species inside the pellet. The reactivity attained in a fixed bed reactor was high, but simultaneously the efficiency was low, due to formation of inactive phases obtained by masking of ions in the framework of supports. The study also showed that the addition of some binders (NaBO2) in the preparation stage of zinc titanites allows attaining a three-folded strength than the pure sorbent.
