摘要:

采用等体积浸渍法制备了Cu?Cr改性活性炭吸附剂,以模拟焦炉气为原料,考察了不同过渡金属活性组分及其负载量、不同助剂及其负载量、焙烧温度对吸附剂脱除COS性能的影响,并采用XRD、BET、SEM等手段对Cu?Cr改性的吸附剂进行表征。结果表明,Cu和Cr共同改性的活性炭对焦炉煤气中COS的吸附性能最好。Cu?Cr改性活性炭吸附剂较佳制备条件为:Cu负载量为5.0%,Cr负载量为1.5%,焙烧温度为400 ℃。反应温度10 ℃的条件下,改性活性炭吸附剂的穿透硫容为1.47%,且该Cu?Cr改性活性炭吸附剂具有良好的再生利用性能。表征结果显示,CuO和 Cr2O3金属氧化物均匀负载于活性炭上,且失活后的吸附剂比表面积和孔容均减小。

Abstract:

Cu?Cr modified activated carbon adsorbent was prepared by equal volume impregnation method.Using simulated coke oven gas as testing material,the effects of different transition metal active components and their loadings,different additives and loadings,calcination temperature on the removal activity of COS were investigated.The Cu?Cr modified adsorbent was characterized by X?Ray Diffraction (XRD), specific surface area (BET) and scanning electron microscope (SEM). The results show that the activated carbon modified simultaneously by Cu and Cr has the best adsorption performance of COS for coke oven gas, and the optimized preparation conditions of Cu?Cr modified activated carbon adsorbent are as follows: Cu and Cr loading is 5.0%, and 1.5% respectively, calcination temperature is 400 ℃. When the reaction temperature is 10 ℃, the breakthrough sulfur capacity of the modified activated carbon adsorbent is 1.47%, and the Cu?Cr modified activated carbon adsorbent shows good recycling performance. The characterization results indicate that CuO and Cr2O3 metal oxides are uniformly loaded on the activated carbon, and the specific area and pore volume of the adsorbent decrease after deactivation.
