FIELD: chemical industry. SUBSTANCE: claimed process for preparing elementary sulfur from hydrogen containing gas mixture comprises stages of partial combustion to separate elementary sulfur, catalytic reaction of hydrogen sulfide contained in partial oxidation product with sulfur dioxide formed during partial combustion and separation of the resulting elementary sulfur, hydrogenation and, optionally, hydrolysis of the outgoing gas of said catalytic reaction and direct catalytic oxidation to separate the resulting elementary sulfur. Said catalytic reaction and direct catalytic oxidation are carried out in one stage. EFFECT: more efficient preparation process. |
