Neutralization of the toxic gas hydrogen sulfide is an important step in almost every natural gas processing plant. A novel method for the conversion of hydrogen sulfide is a combination of bromination and oxidation reactions (BrOx). The first of those, the bromination of hydrogen sulfide, is investigated experimentally. An analysis of the potential by‐products reveals that their formation during the reaction can be excluded. Furthermore, a parameter study showed that reaction yields of up to 94 % are achievable by suitable reaction conditions.

Hydrogen sulfide is a toxic gas that is almost always present in the processing of crude oil or natural gas and must be removed. In addition, hydrogen can be used as an energy carrier if it can be separated from H 2 S. In this work, as the first step of a reaction cycle that could achieve just that, the bromination and chlorination of hydrogen sulfide are experimentally studied. It can be shown that both halogens are capable of completely converting hydrogen sulfide in a gas phase reaction. While the chlorination can produce byproducts, the bromination is free of such.
