摘要 利用金属离子负载的阴离子模板介孔二氧化硅(M-AMS-2)材料,作为脱除天然气中有机硫化物甲硫醚的吸附剂。实验考察了制备吸附剂的反应时间、改性溶液浓度及体积,不同金属离子溶液和煅烧温度等对于M-AMS-2材料吸附脱除甲硫醚性能的影响。实验结果表明,负载铜离子和银离子后的AMS-2材料对甲硫醚均有较好的吸附效果,吸附量以硫计最高分别可达到9.811 1 和14.250 8 mg/g。但从成本方面考虑,Cu-AMS-2型吸附剂的应用前景更广。

Abstract: The metal ion modified anionic surfactant templated mesoporous silica (AMS-2) materials were used as adsorbents to remove the dimethyl sulfide (DMS) which was considered to be the most difficultly removed organic sulfide at ambient conditions in the fuel cell industry. The performance of these M-AMS-2 materials which were prepared by changing different metal ion solutions, reaction time, concentration and volume of the modified solutions, calcination temperature and so on as DMS adsorbents was tested using a dynamic breakthrough test in the fixed bed. It has been proved that the capacities for DMS removal can reach to 9.811 1 and 14.250 8 mg/g of Cu-AMS-2 and Ag-AMS-2 materials respectively. Comparing the cost of the Cu-AMS-2 and the Ag-AMS-2 materials, the Cu-AMS-2 material will be applied widely in the future.
