“…In recent years, various desulfurizers have been widely explored to capture H 2 S with the participation of oxygen in a relatively wide temperature region. , Transition metal oxides and rare earth oxides loaded on various porous materials show a satisfactory desulfurization performance at medium and high temperatures. , However, the performance of these sorbents drops rapidly to less than 50 mg/g in the absence of oxygen gas. − In fact, it is recognized that metal oxide sorbents act as catalysts in capturing hydrogen sulfide with the presence of oxygen gas. , Moreover, a large number of studies have also proved that the desulfurization performance of sorbents under dry conditions is much lower than that in the presence of water vapor. , As reported, the presence of water in the desulfurization system has a positive effect, which has been proven to enhance the hydrolysis of H 2 S . In general, there is a lack of research on selective desulfurization under the conditions of low temperature, dry, and anaerobic, which is an urgent problem to be solved in metallurgy and chemical industries.…”
