以廉价的多孔氧化铝为硅源，采用低温固相反应法制备了新型Li 4SiO 4基高温CO2捕集剂。考察了不同原料配比对CO2吸收能力的影响。结果表明，原料配比对CO2吸收量有影响。当原料配比为2.6：1时，在50 mL/min的N2和50 mL/min的CO2气氛下，CO2吸收量达到30.32wt%（理论吸收量的83%）。同时，实验结果表明，以高岭土为原料制备的Li 4SiO 4基吸附剂具有良好的吸附-脱附性能。
Using inexpensive porous diatomite as silicon source, novel Li4SiO4-based sorbents for high temperature CO2capture were prepared through the solid-state reaction method at lower temperature (700°C). Effect of different raw material ratios on CO2absorption capacity was investigated. The results showed that CO2absorption capacity was dependent on the raw material ratio. When the raw material ratio was 2.6:1, the CO2absorption capacity reached 30.32wt% (83% of the theoretical absorption capacity) in the atmosphere (50mL/min N2and 50mL/min CO2). Meanwhile, it was found that the as-prepared Li4SiO4-based sorbents from diatomite exhibited good absorption–desorption performance.
