1. 毕业设计(论文)的内容和要求
本课题旨在进一步研究开发新型胺改性碳气凝胶吸附剂用于二氧化碳吸附,并进行系列表征手段用于筛选最佳吸附剂。
使用该吸附剂,通过系列co2吸附实验,提高吸附剂对co2的吸附容量及吸附选择性,并初步探究胺改性气凝胶对co2的吸附机理,从而进一步寻找提高其吸附效果的改性方法。
论文内容:1)载体碳气凝胶的制备:制备系列rf、mf气凝胶,探究以ctab及na2co3为催化剂催化生成气凝胶的影响,采用磷酸,氢氧化钾及二氧化碳对碳气凝胶进行活化,通过xrd,bet等系列表征筛选出高比表面积介孔气凝胶材料;2)载体碳气凝胶的胺改性:采用mea、pei、aptms等有机胺溶液对气凝胶进行改性,通过热重探究其负载情况;3)使用胺改性的碳气凝胶对co2进行吸附实验,探究其对co2 的吸附容量及吸附选择性。
