Advanced sorbent development program. Annual report, November 1, 1994--November 30, 1995
The overall objective of this program is to develop regenerable sorbents for hydrogen sulfide removal from coal-derived fuel gases in the temperature range 343--538 C. Two categories of reactor configurations are being considered: fixed-bed/moving-bed reactors and fluidized-bed (bubbling and circulating) reactors. 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 (100 cycles) of the best fixed-bed/moving-bed and fluidized-bed sorbents will be conducted. The sorbents will have chemical characteristics that permit cyclic regeneration over many cycles without a drastic loss of activity. They must also have physical characteristics that are compatible with the selected reactor, e.g., fixed vs fluidized bed, and which remain acceptable during absorption and regeneration. The sorbents must be capable of reducing the hydrogen sulfide level in the fuel gas to less than 20 ppmv in the specified temperature range and pressures in the range of 1 to 20 atmospheres. The proposed program is divided into several tasks: NEPA Report; Sorbent Preparation; Provision of Bench Unit; Bench Testing; Sorbent Cost Assessment; Topical Report; Market Plan; and Long-Term Testing. Progress on each of these is described.
