- Abstract
- Cobalt sulfide supported on alumina was found to have a potential use as a device trapping elemental sulfur over the temperature range 300-400 (degrees)C. Elemental sulfur in the gas phase can be removed during the deep sulfidation reaction with an accompanying phase change from Co(9)S(8) to CoS(2). Constant removal efficiency above 90% was achieved regardless of concentration difference in the inlet sulfur within a tested range of 900-4500 ppm. The sorbent can be easily regenerated by using hydrogen gas at the temperature range of 350-400 degreesC in a very short time period of less than 1 h. A repeated multicyclic test of absorption and regeneration has shown that the process is reversible and there is no appreciable sintering of particle size.
