In this program, the effort is geared towards developing advanced mixed-metal oxide sorbents for desulfurization in moving-bed systems in the temperature rang 343-538{degrees}C (650-1000{degrees}F) where technical viability and process efficiency result in lower overall process costs. In addition a cost assessment and a market plan for large-scale fabrication of sorbents will be developed. As an optional task, a long-term bench-scale testing of the best moving-bed sorbent formulation will conducted. The sorbents must have chemical characteristics that permit cyclic desulfurization and regeneration over many cycles without a drastic loss of activity. The sorbents must be capable of reducing the hydrogen sulfide level in the fuel gas to less than 20 ppm in the specified temperature range and pressures in the range of 1 to 20 atmospheres. In addition, they must also have physical characteristics that are compatible with the selected reactor, e.g. pellet size/shape. This paper discusses in more detail recent developments in the fabrication and use of doped zinc titanate sorbents for moving-bed configurations at temperatures below 538{degrees}C (1000{degrees}F).
