Abstract: A series of conversion-absorption ZnO based desulfurizers were prepared by using industrial
ZnO and ZnO obtained by basic zinc carbonate decomposition as active component respectively, γ-Al 2O 3 as
structure additive and K 2CO 3 as basic additive. The effects of ZnO precursors and γ-Al 2O 3 precursors on
the desulfuration properties of prepared ZnO based desulfurizers were investigated at 300℃ and
–1
atmospheric pressure with a gas space velocity of 2000 h . The results showed that the pore structure and
basicity of ZnO based desulfurizers could significantly affect their desulfurization properties. The
desulfurizer using ZnO obtained by basic zinc carbonate decomposition as the active component had high
removal efficiency and good breakthrough sulfur capacity, and the breakthrough sulfur capacity was
increases about 10 times comparing with that of the desulfurizer using industrial ZnO as the active
component. In addition, the γ-Al 2O 3 prepared by different precursors had influences on the desulfurization
properties of the prepared ZnO based desulfurizers. The γ-Al 2O 3 decomposed from pseudo boehmite
obviously improved desulfurization properties of the desulfurizers, the breakthrough sulfur capacity was
12.18%. Among these desulfurizers, the desulfurizer using ZnO decomposed from basic zinc carbonate as
the active component, γ-Al 2O 3 decomposed from pseudo boehmite as the structure additive and K 2CO 3 as
the alkaline additive, could convert and absorb COS with a COS conversion of 99.98% and a breakthrough
sulfur capacity of 4.03%.
