Metal oxides exhibit highest adsorption capacities towards H2S but are challenged by lack of regenerability due to sulfide layer formation during adsorption, sulfate phase formation during regeneration, sintering, spalling, and sublimation. Protectio

Current regulations of SO x emissions require Sulfur Recovery Units (SRUs) to achieve recoveries in excess of 99.9%. Capital cost of existing commercial Claus Tail gas clean up technologies capable of achieving that benchmark can amount to 45% of the

Spatially well-distributed copper-zinc oxides supported on mesoporous silica (SBA-15 and commercial silica gel) showed high adsorption capacity for hydrogen sulfide (as high as 80 mgS/gsorbent) and stability during cyclic adsorption-regeneration proc
