摘要:

金属氧化物捕获二氧化碳(CO2)技术是减少碳排放的有效手段,然而其在捕获CO2方面存在吸附容量低和易板结等问题。目前,熔盐改性金属氧化物可有效解决以上问题。以水滑石类衍生镁铝氧化物、氧化镁和氧化钙为研究对象,综述了掺杂熔盐(如硝酸盐、亚硝酸盐、碳酸盐等)对金属氧化物捕获CO2性能的影响,分析了熔盐的改性机制,归纳了金属氧化物捕获CO2的应用进展。未来应更多关注熔盐掺杂体系设计、低成本高选择性吸附材料研发以及CO2捕获机制研究。同时,在实验中应尽可能模拟实际工况,为后续大规模工业应用提供支持。

Abstract:

CO2 capture technology by metal oxide is an effective method for carbon emission reduction.However,metal oxides in CO2 capture have some problems,such as low adsorption capacity and easy hardening.At present,molten salt modification of metal oxide can effectively solve these problems.The hydrotalcite derived magnesium aluminum oxides,MgO and CaO were studied.The effects of doped molten salts(such as nitrate,nitrite,carbonate,etc.) on the CO2 capture performance of metal oxides were reviewed.The modification mechanism was analyzed and the application progress of CO2 capture by metal oxides was summarized.In the future,more attention should be paid to the design of doped molten salt system,the study of low-cost and highly selective adsorption materials and the study of capture mechanism.At the same time,practical working conditions should be simulated as much as possible in the experiment to provide support for subsequent large-scale industrial applications.

Key words: carbon dioxide, metal oxides, molten salts, adsorption, capture
