Effects of addition of Mo on the sulfidation properties of Fe-based sorbents supported on fly ash during hot coal gas desulfurization

Gas-phase removal of hydrogen sulfide using iron oxyhydroxide at low temperature: Measurement of breakthrough curve and modeling of sulfidation mechanism

“…The life of the catalyst decreases to only a few days or even a few hours in the presence of H 2 S with a concentration of a few ppm [2]. In the IGCC process, it is necessary to reduce the emission of the sulfur impurities as well as avoid corrosion of the process facilities [5][6][7][8]. The acceptable H 2 S concentration for gas turbines in the IGCC process is about 1 ppm [7].…”

“…The efficient removal of H 2 S has been a strategic issue in relation to many industrial processes and energy devices, such as X to liquid (XTL) processes, integrated gasification combined cycle (IGCC) processes and proton exchange membrane fuel cells (PEMFCs) [2][3][4][5][6][7][8][9]. In the Fischer-Tropsch based XTL process, the sulfur poisoning of the catalysts has been a difficult problem to solve [2][3][4].…”

H2S adsorption and decomposition on the gradually reduced α-Fe2O3(001) surface: A DFT study

“…Based on this, there were many investigations of single metal oxide and mixed metal oxides as sorbents in the past [7][8][9][10][11]. And iron oxide has become the study focus for advantages of low cost, high sulfurization rate, good regeneration ability and superior sulfur capacity [12][13][14][15].…”

High-temperature desulfurization of hot coal gas on Mo modified Mn/KIT-1 sorbents

“…High and cold temperature gas desulfurization (HGD and CGD) technologies have attracted more attentions and a lot of works have been done on developing sorbent. Because the thermodynamic performance is expected to improve and the plant configuration could be simplified, the HGD technology is more attractive than the CGD method [13][14][15][16].…”
