Abstract

Perovskite LaMnO₃/ZSM-5 was used for reactive adsorption of hydrogen sulfide at 500–700 °C. The sorbents showed good desulphurization performance, the highest sulfur capacity of 1020 µmol S/g over 5La5Mn/ZSM-5 was obtained at 600 °C. The reducing gases (H₂ and CO) can obviously shorten the breakthrough time and reduce the sulfur capacity. Incorporating Mn ions into La₂O₃ lattice improved the sulfidation activity due to the formation of perovskite LaMnO₃ with good reducibility and structure stability.
