Testing and analysis of METC10 sorbent

PDF Version Also Available for Download.

Description

Development of a suitable regenerable sorbent is a major barrier issue in the Hot Gas Cleanup program for Integrated Gasification Combined Cycle systems. This has been a challenging problem for the last 20 years. Many of the sorbents developed in prior work did not retain their reactivity and physical integrity during repeated sulfidation/regeneration cycles. This paper is a report on a promising sorbent (METC10) developed at the Morgantown Energy Technology Center (METC) which has demonstrated sustained reactivity and physical integrity during repeated sulfidation and regeneration cycles. METC10 sorbent was tested in a low pressure (260 kPa/23 psig) fixed-bed reactor at ... continued below

Description

Development of a suitable regenerable sorbent is a major barrier issue in the Hot Gas Cleanup program for Integrated Gasification Combined Cycle systems. This has been a challenging problem for the last 20 years. Many of the sorbents developed in prior work did not retain their reactivity and physical integrity during repeated sulfidation/regeneration cycles. This paper is a report on a promising sorbent (METC10) developed at the Morgantown Energy Technology Center (METC) which has demonstrated sustained reactivity and physical integrity during repeated sulfidation and regeneration cycles. METC10 sorbent was tested in a low pressure (260 kPa/23 psig) fixed-bed reactor at 538{degrees}C (1,OOO{degrees}F) with simulated air blown K Rust Westinghouse (KRW) coal gas. The sorbent was subjected to 3.5 sulfidation/regeneration cycles using steam as the regeneration diluent. There were no appreciable changes in reactivity during the 3.5 cycles and spalling or other physical deterioration was not observed. Sorbent pellets, which were prepared by a commercial vendor (United Catalysts, Inc.) to METC specifications, were exposed to fifty sulfidation/regeneration cycles using conditions typical of the Tampa Electric Company (TECO) Clean Coal Technology (CCT) demonstration project. After the fiftieth sulfidation cycle, both the sulfur loading value (more than 6 lb/ft{sup 3}) and the attrition (less than 5 wt%) satisfied the requirements necessary for the TECO/CCT project. These sorbent pellets were also tested with real coal gas for 240 hours in a moving bed reactor at General Electric (GE) company. Sulfur absorption was according to the sorbent movement rate and the attrition rate was very low during 240 hours of the pilot plant operation.
