摘要: The reaction of H 2 S selective partial oxidation to elemental sulfur was studied on cordierite honeycomb-structured catalysts in the range of temperature of 150–200° C. The preparation procedure of catalytic cordierite monoliths has been studied, from the washcoating with CeO 2 to the deposition of V 2 O 5 by wet impregnation. Two different preparation washcoating procedures deposition were studied: in one case the washcoat had been already added with the salts precursors of the active species (joint impregnation method), in other case the …
