粉煤灰基硅铝酸盐材料的合成及其捕集CO2的研究进展
Research progress in preparation of fly ash based aluminosilicate materials and their CO2 capture
摘要
Abstract
The escalating emissions of CO2 exacerbate global warming.Carbon capture offers a potential avenue to attenuate CO2 emissions,but the high cost of adsorbents acts as a barrier to the development of carbon capture technologies.Simultaneously,the continual increase in coal combustion leads to a rise in fly ash production,yet its valorization remains relatively low.Utilizing fly ash for synthesizing fly ash-based aluminosilicate materials and their application in carbon capture technologies present a dual solution by valorizing industrial solid waste and reducing carbon emissions.The preprocessing steps prior to synthesizing fly ash-based aluminosilicate materials were outlined and the research on synthesis of fly ash-based zeolites,Li4SiO4 adsorbents,and SiO2 mesoporous materials and their synthesis were systematically discussed,and the kinetics of CO2 adsorption on fly ash-based aluminosilicate materials were summarized.Physical and chemical preprocessing steps before preparing fly ash-based aluminosilicate materials optimize the materials'pore structure and surface chemical properties.Strategies such as amine functionalization or metal ion doping enable control over the material structure and CO2 capture performance.Discrepancies in the kinetics of CO2 capture on fly ash-based aluminosilicate materials arise from variations in reaction products and capture conditions.In-depth theoretical research and promoting large-scale engineering applications hold significant promise in guiding the development of carbon capture technologies.关键词
