A Study of Desulfurization Ability and Activation Energy for CuO-AgO Sorbents
In this study, we investigated desulfurization abilities and activation energy using TGA for CuO-AgO sorbents calcined at 700 ℃. CuO was used as a main active material and AgO was used as an additive material and 25 wt% SiO2 was used as a support material. The desulfurization reaction temperatures were 450 ℃, 500 ℃, and 550 ℃ and the regeneration reaction temperature was 700 ℃. From the TGA experiments, the best sulfur loading of CAS1 sorbent containing 1 wt% AgO was about 14.95 g sulfur/100 g sorbent at 550 ℃. The activation energy was calculated by the Chatterjee-Conrad method based on the TGA experiment. Desulfurization ability and activation energy of sorbent were decreased as the content of AgO increased.
