| Popis: | Using inexpensive porous diatomite as silicon source, novel Li 4 SiO 4 -based sorbents for high temperature CO 2 capture were prepared through the solid-state reaction method at lower temperature (700 °C). Effect of different raw material ratios on CO 2 absorption capacity was investigated. The results showed that CO 2 absorption capacity was dependent on the raw material ratio. When the raw material ratio was 2.6:1, the CO 2 absorption capacity reached 30.32 wt% (83% of the theoretical absorption capacity) in the atmosphere (50 mL/min N 2 and 50 mL/min CO 2 ). Meanwhile, it was found that the as-prepared Li 4 SiO 4 -based sorbents from diatomite exhibited good absorption–desorption performance. |
