“…Sulfur compounds represent one of the major problems to the oil and gas industry, being regarded as impurities that imparts undesirable characteristics to both the matrix and final products . Among these compounds, hydrogen sulfide, H 2 S, poses a significant challenge to the industry due to its notorious toxicity, corrosiveness, and ability to contaminate catalysts. − Most of the hydrogen sulfide present in oil and gas comes from anthropogenic actions during the refinement process, such as the hydrodesulfurization (HDS), employed to convert sulfur compounds into hydrocarbon, releasing H 2 S. − …”
