Process for desulfurizing crude gas from gasifying carbonaceous materials

摘要

Oxygen-containing gas is blown into the filter unit to prevent the formation of COS in a process for desulfurizing crude gas from gasifying carbonaceous materials in a reducing atmosphere. Process for desulfurizing crude gas from gasifying carbonaceous materials in a reducing atmosphere comprises converting hydrogen sulfide in the crude gas to water and elemental sulfur by adding oxygen, absorbed by the dust particles and removing from the crude gas using a filter unit. To prevent the formation of COS oxygen-containing gas is blown into the filter unit.
