How is hydrogen sulfide formed
Hydrogen sulfide is most commonly obtained by its separation from sour gas, which is natural gas with a high content of H 2S. It can also be produced by treating hydrogen with molten elemental sulfur at about 450 °C. Hydrocarbons can serve as a source of hydrogen in this process.
