Hot Coal Gas Desulfurization With Manganese-Based Sorbents
The objective of this project is to develop a pellet formulation which is capable of achieving low sulfur partial pressures and a high capacity for sulfur, loaded from a hot fuel gas and which is readily regenerable. Furthermore the pellet must be strong for potential use in a fluidized bed and regenerable over many cycles of loading and regeneration. Regeneration should be in air or oxygen-dep...
متن کاملCore-in-shell sorbent for hot coal gas desulfurization
A core-in-shell sorbent is described herein. The core is reactive to the compounds of interest, and is preferably calcium-based, such as limestone for hot gas desulfurization. The shell is a porous protective layer, preferably inert, which allows the reactive core to remove the desired compounds while maintaining the desired physical characteristics to withstand the conditions of use.
متن کاملNatural Gas Odorants Desulfurization
This study investigates the use of activated carbon for the odorant removal from natural gas to be used for synthesis gas production for fuel cells. The odorants used in this study were dimethyl sulfide, tetrahydrothiophene, methyl mercaptan, and t-butyl mercaptan. It was concluded that only physical adsorption is contributing towards removal of sulfur species at lower temperatures, whereas the...
متن کاملFlue gas desulfurization
Flue gas desulfurization is commonly known as FGD and is the technology used for removing sulfur dioxide (SO2) from the exhaust combustion flue gases of power plants that burn coal oroil to produce steam for the turbines that drive their electricity generators. The most common types of FGD contact the flue gases with an alkaline sorbent such as lime or limestone. As sulfur dioxide is responsibl...
متن کاملCu-Cr-O and Cu-Ce-O Regenerable Oxide Sorbents for Hot Gas Desulfurization
Binary Cu-Cr-O and Cu-Ce-O oxides were studied in this work as regenerable sorbents for high-temperature fuel gas desulfurization. CuO-Cr2O3 and CuO-CeO2 sorbents can remove H2S from simulated coal-derived fuel gas to less than 5-10 ppmv in the temperature range of 650-850 °C. The presence of stable CuCr2O4 in CuO-Cr2O3 solids retains some copper in the Cu2+ or Cu1+ oxidation state, which can a...
