Hydrogen Sulfide Removal, Recovery, and Conversion Technologies
This community focuses on the capture, removal, and conversion of hydrogen sulfide and related sulfur compounds from industrial gas streams, wastewater, and sewer systems, primarily to enable hydrogen production and elemental sulfur recovery.
The work centers on catalytic and adsorptive methods for processing hydrogen sulfide, carbonyl sulfide, and other acid gases. Recurring techniques include selective oxidation, catalytic hydrolysis, and adsorption using activated carbon, metal oxides, and doped catalysts. Applications span natural gas purification, blast furnace gas treatment, biogas upgrading, and sewer odor control. A significant portion of the research addresses the conversion of hydrogen sulfide into usable hydrogen and elemental sulfur, often through electrochemical splitting or low-temperature oxidation processes. The community also investigates the mitigation of sulfide-induced corrosion in concrete infrastructure and the management of sulfur compounds in wastewater treatment.
The largest share of the community's output is found in sulfur research, accounting for 90.0% of all sulfur research tracked, with 2,430 papers. Hydrogen research follows with 30.0% of its total research volume, contributing 1,737 papers to this group.
The community comprises 4,027 papers, publishing most frequently in the International Journal of Hydrogen Energy, Fuel, and Chemical Engineering Journal.
Recent work continues to focus on improving the efficiency and durability of catalysts for low-temperature hydrogen sulfide oxidation and carbonyl sulfide hydrolysis, particularly for blast furnace gas purification and electrochemical hydrogen production.
