This work studied the H2S removal from biogas, a CO2-containing gas mixture, over nitrogen-doped carbon materials deriving carbonization of ZIF-8. The sorption performance on series N-doped porous was investigated, in which N-doping composition and textural properties adsorbents were turned by varying temperatures. By changing temperatures 750 to 950 ℃, N contents vary range 17.75−5.46 wt.%, BE...
Objective: The purpose of this study was to develop a novel colorimetric system for direct detection of hydrogen sulfide on the tongue dorsum from subjects with complaints of halitosis. Method: An assay system comprised of a cotton swab impregnated with zinc sulfate, attached chromatography paper, stabilizing solution, and coloring reagents for the methylene blue technique was developed. Using ...
Along with oil and gas operations, huge amounts of sulfur byproducts are produced. For example, in the State Qatar which has third largest proven reserves natural gas, an incredible amount is produced as byproduct from its processing facilities. The surpasses by far that can be utilized currently country. Hydrogen sulfide (H2S) existing extracted Qatar’s North Field converted to elemental using...
