变温镁基co2吸附剂的制备及应用i.na/mg物质的量比
, PP. 884-889
Keywords: 镁基吸附剂,二氧化碳,变温吸附
Abstract:
？以mg（no3）2和na2co3为原料，采用正加沉淀法制备镁基co2吸附剂，利用xrd、sem-eds和dtg等方法对吸附剂进行了表征，研究了n（na）/n（mg）比对吸附剂的物质组成、形貌和分解温度的影响；在此基础上，通过变温吸附脱附动态循环实验考察了不同吸附剂的co2吸附性能。实验结果表明，当n（na）/n（mg）为8.15时，吸附剂颗粒粒径小、大小均匀、分解温度低，吸附容量达到9.584%（质量分数）；经过20次变温吸附脱附循环后，吸附能力仍保持初始吸附量的95.8%，表现出良好的稳定性。
