Desulfurizers CuO supported ATP were prepared using direct precipitation method and applied for sorbing H2S at ambient temperature.XRD and TEM were employed to characterize the desulfurizes. The effects of calcination temperature
CuO loading
gas flow rate and reaction temperature on the desulfurization performance were investigated.The diffusion and thermodynamics data demonstrate that dispersion state of CuO on the support depends highly on calcination temperature and CuO loading.Over-calcination or over-loadings may result in serious destructive and different dispersion state of CuO
which cause rapid decline of desulfurizer activity.Low gas flow rates are benefit for sorption capacity and the usage ratios of the sorbents can reach to 97%.When reaction temperature is at 0℃
the desulfurizers still be of high capacity 33.17%.
