Development of a High Temperature Steam Regenerative H2S Removal Process Based onAlumina Supported MnO and FeO

摘要

The aim of the study was to develop a process that removes H2S and COS at hightemperatures (675-1075 K) from fuel gases produced by a coal gasifier. These fuel gases can be used for the production of electricity in a combined cycle power plant, or as a synthesis gas for the production of substitute natural gas (SNG) or chemicals. The overview of literature on H2S removal showed that a number of low temperature H2S removal processes have been developed and used. High temperature processes are in the development stage, but not applied yet. The main attention is concentrated on the development of zinc ferrite, zinc titanate, the mixed metal oxide process and iron oxide on silica.
