Abstract

A series of supported catalysts based on ceramic type supports (ZrO₂-SBA15 and ZrO₂-La₂O₃) and refractory metals (Mo,Cr) were prepared and tested in the methane reforming with hydrogen sulfide (H₂S). The main products of the reaction were hydrogen (H₂) and carbon disulfide (CS₂). The physicochemical properties of these catalysts were characterized by XRD, STEM and N₂-BET methods mainly. The evolution of crystalline phases along the reaction led to formation of sulfides and carbides, i.e., MoS₂, ZrS₂ and the carbides MoC, Mo₃C₂, which could be the active phases. At high temperatures (1073 K-1123 K) the SBA-15 structure collapses while formation of mixed phases occurs i.e., ZrSiO₄; the CH₄ and H₂S conversion rates were dependent on temperature and catalysts composition, however, the evolution of crystalline phases at high temperatures seems essential for achieving high activity and selectivity.
