METHOD FOR THE PURIFICATION OF HYDROGEN SULFIDE-CONTAINING GASES |
摘要 |
METHOD FOR TEE PURIFICATION OF HYDROGEN SULFIDE-CONTAINING GASES A starting hydrogen sulfide-containing gas is purified by way of a two-stage oxidation to elemental sulfur with oxygen which is supplied in an amount of 100-110% of the stoichiometric quantity necessary for oxidizing hydrogen sulfide to elemental sulfur. Oxidation at the first stage is carried out in a fluidized bed of a granular catalyst containing 10 -20% by mass of magnesium chromite on aluminium oxide, At the second oxidation stage, the unreacted hydrogen sulfide and oxygen from the first stage are reacted at 140-155.degree.C in the presence of a catalyst to form elemental sulfur. The invention may be used in decontamination of natural gases high in hydrogen sulfide, gas releases of oil refinery and coke chemical plants. |
