WebBiologically produced sulfur particles have various shapes and sizes. A common feature is the typical bipyramidal shape for elemental sulfur. The bipyramids were found as single crystals or in agglomerates. The agglomerates showed better settleability than single crystals (91% settled compared to 78.3% settled after 2 hours), unless the crystal ... WebDec 21, 2024 · In the 1990s a biological desulfurization process was developed for the removal and conversion of toxic H 2 S from sour gas streams. In this process, H 2 S is absorbed in a haloalkaline (bi)carbonate buffer solution (i.e., >1 M Na + and a pH of 8–10) and subsequently oxidized into predominantly elemental sulfur (S 8) by haloalkaliphilic …

Elemental sulfur is used mainly as a precursor to other chemicals. Approximately 85% (1989) is converted to sulfuric acid (H2SO4): 1⁄8 S8 + 3⁄2 O2 + H2O → H2SO4 In 2010, the United States produced more sulfuric acid than any other inorganic industrial chemical. The principal use for the acid is the extraction of phosphat…
WebDec 15, 2011 · SOB produce elemental sulfur as an intermediate in the oxidation of hydrogen sulfide to sulfate [11], [12], [13]. On the other word, SOB oxidize sulfide to sulfur particles, and then the produced sulfur particles are biologically oxidized to sulfate. According to this fact, sulfur and sulfate production are consecutive reactions. Thus, Eq.
