Abstract	Various CuO-based sorbents were prepared to investigate effects of sorbent ingredients such as SiO$_{2}$, MnO$_{2}$, and MoO$_{3}$ on desulfurization reactivity. Several candidate sorbents chosen from a TGA screening test were further tested in a microreactor system. The amount of SiO$_{2}$ support to minimize sintering of sorbents was 25 wt%. Sulfur loading was seriously affected by the amount of additives (MnO$_{2}$, MoO$_{3}$) in a multi-cycle test. Improvement of sulfur loading by the additives was observed in the multi-cycle test. Effects of support materials on sulfur loading were also investigated by using SiO$_{2}$, g-alumina and zeolite. SiO$_{2}$ showed the best performance among the support candidates. The sorbent showing the best sulfur loading ability was CMS6 (CuO :MoO$_{3}$ : MnO$_{2}$ : SiO$_{2}$=61 : 11 : 3 : 25). Its sulfur loading reached up to 13.8 g sulfur/100 g sorbent in a multi-cycle test.
