摘要
以纳米CuO/ZnO作为去除H2S的活性组分,考察了反应温度、空速、氧分压等反应条件和掺铜量对纳米CuO/ZnO脱硫性能的影响,并分析了CuO对脱硫剂脱硫机理的影响。结果表明:脱硫剂TZ2(Cu:Zn物质的量比为1:18.40)有较高的脱硫性能;空速越低脱硫性能越高;反应温度由25℃升高到120℃,脱硫性能先下降后升高,120℃的脱硫性能略高于25℃;氧分压为10%时,有最佳的脱硫性能;CuO的加入增大了脱硫产物向多硫化物及单质硫的转化。
With nano crystalline CuO/ZnO as the active components for removing H2S, the effects of active conditions, such as active temperature; space velocity, and partial pressure of oxygen, and the copper contents, to the performance of desulfurization with nano CuO/ZnO has been researched. And the effect of CuO to the desulfurization mechanism is also analysed. It is indicated that the desulfurizer TZ2 （the mole ratio between Cu and Zn is 1 to 18.40） has strong performance of desulfurization,when the space velocity is slower, the performance of desulfurization is much more effective. When the reactive temperature is increased from 25℃ to 120℃, the performance of desulfurization is improved from the poor beginning, i.e the performance at 120℃ is a little enhanced than that at 25℃. And when the partial pressure of oxygen is of 10%, the performance of desulfurization is excellent.Therefore, it is concluded that the adding of CuO makes the products of desulfurization convert greatly into multi-sulfur and the element sulfur.
