一种电厂烟气中CO2资源化利用的方法
摘要：
本发明涉及一种电厂烟气中CO2资源化利用的方法，属于能源环境催化技术领域。首先用浸渍法制备NiO/γ?Al2O3催化剂，然后将NiO/γ?Al2O3催化剂进行预处理；采用溶胶?凝胶法制备具有K2NiF4结构的透氧膜材料，然后将K2NiF4结构的透氧膜材料按工艺制成管状膜材料；将制备得到管状膜材料外侧面均匀涂覆NiO/γ?Al2O3催化剂得到膜管，最后安装到管状膜反应器内；得到膜管外侧通入CH4或者焦炉煤气，膜管内部通入含CO280wt%以上的电厂烟气，升温反应后实现对电厂烟气中CO2资源化利用。本发明提出了利用管状膜反应器对电厂烟气中的CO2资源化利用，这一过程不仅实现CO2的综合回收利用与CO2的减排，同时还实现了甲烷的催化氧化。
