Perovskite LaMnO3/ZSM-5 was used for reactive adsorption of hydrogen sulfide at 500-700 A degrees C. The sorbents showed good desulphurization performance, the highest sulfur capacity of 1020 A mu mol S/g over 5La5Mn/ZSM-5 was obtained at 600 A degrees C. The reducing gases (H-2 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.
