Nanometer desulfurizing agent, preparation method and reaction system

The invention provides a nano desulfurizing agent, a preparation method and a system. The nano desulfurizing agent comprises nano Al2O3, nano ZnO and nano CuO, wherein the molar ratio of the nano Al2O3 to the nano ZnO to the nano CuO is (0.8-1.5): (0.8-1.5): (1.8-2.5). Compared with the prior art, the method has the beneficial effects that the desulfurizing agent provided by the invention adopts the rotary liquid film reactor to carry out coprecipitation reaction, and after hydrothermal crystallization reaction is carried out, the desulfurizing agent of a nano Al2O3, nano ZnO and nano CuO three-nano oxide system with the sulfur capacity of 15% or above is obtained, and the desulfurizing activity and sulfur capacity of the desulfurizing agent are greatly improved. 本发明提供一种纳米脱硫剂、制备方法及系统，所述纳米脱硫剂包括纳米Al2O3、纳米ZnO及纳米CuO，所述纳米Al2O3、所述纳米ZnO及所述纳米CuO的摩尔比为：(0.8～1.5)：(0.8～1.5)：(1.8～2.5)。与现有技术相比，本发明的有益效果在于：本发明脱硫剂采用旋转液膜反应器进行共沉淀反应，在进行水热晶化反应后得到硫容在15％以上的纳米Al2O3、纳米ZnO及纳米CuO三种纳米氧化物体系的脱硫剂，其脱硫活性和硫容大幅度提升。
