摘要 采用阴离子模板介孔二氧化硅(AMS)材料负载银离子,作为吸附剂脱除天然气中最难除去的有机硫化物甲硫醚。在固定床中考察了制备吸附剂的反应时间、改性溶液浓度及体积和煅烧温度对于Ag-AMS介孔材料吸附脱硫性能的影响。实验结果表明,Ag-AMS介孔材料适宜的离子交换条件为:AgNO_3溶液浓度为6.25%,交换温度为常温,反应时间为8 h;煅烧温度为400℃,时间为6 h。在此条件下,Ag-AMS介孔材料对甲硫醚的吸附容量为14.2508 mg硫/g。 采用阴离子模板介孔二氧化硅(AMS)材料负载银离子,作为吸附剂脱除天然气中最难除去的有机硫化物甲硫醚。在固定床中考察了制备吸附剂的反应时间、改性溶液浓度及体积和煅烧温度对于Ag-AMS介孔材料吸附脱硫性能的影响。实验结果表明,Ag-AMS介孔材料适宜的离子交换条件为:AgNO<sub>3</sub>溶液浓度为6.25%,交换温度为常温,反应时间为8 h;煅烧温度为400℃,时间为6 h。在此条件下,Ag-AMS介孔材料对甲硫醚的吸附容量为14.2508 mg硫/g。
