利用Cu+能与CO结合形成羰基络合物,将Cu+盐负载到分子筛表面,经过热处理能达到自发单层分散状态,有效提高了CO的吸附量。利用直接混合法将CuCl负载于13X分子筛表面上制备高效的CO专用吸附剂。实验结果表明,将样品置于管式炉内,流动N2氛围保护下,在350℃焙烧4h后,CuCl/13X质量比0.4∶1.0吸附剂表现出较好的吸附性能,CO吸附量可达45mL/g,对工业分离混合气体有重要的意义。XRD也显示,不同质量比的CuCl/13X样品,在N2氛围中350℃焙烧4h后,CuCl晶相峰从有变无,说明CuCl均匀分散于载体表面,提供了更多的与CO络合的铜离子活性中心,进而提高了吸附剂对CO的吸附量。
Cu + can be combined with CO to form carbonyl complexes, and Cu + salt can be loaded on the surface of zeolite. After heat treatment, spontaneous monolayer dispersion state can be achieved, which effectively increases the adsorption amount of CO. CuCl was loaded on the surface of 13X molecular sieve by direct mixing method to prepare efficient CO-specific adsorbent. The experimental results show that the CuCl / 13X mass ratio 0.4:1.0 adsorbent shows good adsorption performance when the sample is placed in a tube furnace under N2 flow protection and calcined at 350 ° C. for 4 h, and the CO adsorption capacity can reach 45 mL / g, the industrial separation of mixed gas is of great significance. XRD also showed that CuCl / 13X samples with different mass ratios calcined at 350 ℃ for 4h in N2 atmosphere show a change in peak of CuCl, indicating that CuCl is uniformly dispersed on the surface of support, providing more complex with CO Copper ion active center, thereby increasing the adsorbent adsorption of CO.
