A technique for determining the concentration of oxygen in hydrogen sulfide is developed on passing the tested hydrogen sulfide through the stainless steel chips and determining the amount of solid sulfur formed over the catalyst’s surface as a result of hydrogen sulfide oxidation by impurities of oxygen. A method for the deep purification of hydrogen sulfide of oxygen is developed. It is shown that under certain conditions, two chemical reactions for the conversion of hydrogen sulfide into two different modifications of sulfur (solid and gaseous) can proceed independently and simultaneously on the catalyst’s surface.
