1. 毕业设计(论文)的内容和要求
课题介绍: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。
课题内容:1)载体碳气凝胶的制备:通过单一变量调控制备系列rf气凝胶,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)对碳气凝胶材料进行co2吸附性能测试,比较各材料对co2的吸附容量,co2/n2吸附选择性,吸附热等性能差异;3)对碳气凝胶材料进行co2动态吸附,动力学测定为工业化应用做前期铺垫。
