“…8. The 50 wt% Mn 100 /KIT-1 exhibited a steep deactivate rate after the breakthrough point with BSC of 161.9 mg S/g sorbent, which is significantly higher than these over 9.2% Mn/activation carbon (54.1 mg S/g sorbent) and over Mn/c-Al 2 O 3 (26.7 mg S/g sorbent), and the latter were used only at 350-400°C [52,32]. This indicated that more metal oxide can be dispersed highly in the support channel and enhance the reactivity of the manganese oxide with H 2 S due to large V p and high S BET of KIT-1.…”

“…Therefore, the physical structure of sorbent plays a very important role in the desulfurization process [26][27][28]. Many inorganic materials, such as zeolite, SiO 2 , c-Al 2 O 3 , activation carbon, CeO 2 and mesoporous silica were used as sorbent supports [29][30][31][32][33] due to the superior dispersion of metal oxide and weak transport resistance. Compared with the other supports, the mesoporous silica is considered to be a more suitable due to its high surface area, large pore volume and narrow pore size distributions.…”

“…Carbon materials [ 14 , 15 , 16 ], natural aluminosilicates [ 17 , 18 ] semi-coke [ 19 , 20 ], nonmetallic oxides [ 21 , 22 , 23 ] and other materials [ 24 ] were studied as the complex, multicomponent H 2 S sorbents. Among impregnated sorbents, active phases often consist of simple metal oxides [ 21 , 22 ].…”

“…In the process of coal coking, through a series of complex physical and chemical reactions, coal was generated into the coke oven gas eventually. Coke oven gas contains a lot of sulfide, hydrogen chloride, hydrogen fluoride and other gases, and trace amount of these compounds can result in the deactivation of the following catalysts and lead to corrosion of the following reaction equipment [1]- [6]. The amount of sulfur in the gas must be decreased to a standardized scope.…”
