| 发明名称 | Method of fabricating pelletized medium-high-temperature CO<sub>2 </sub>sorbent of Ca—Al—CO<sub>3</sub> | ||
| 摘要 | A sorbent for capturing CO2 is fabricated. The sorbent is pelletized and used under a medium or high temperature. The sorbent is mainly made of aluminum calcium carbonate (Ca—Al—CO3). The present invention has a controllable ratio for mixing Ca—Al—CO3 with a release agent (magnesium stearate, MgSt) and a binder (activated carbon, cement or bentonite). The sorbent has a good performance for anti-degradation under a high temperature with 100% of CO2. During 10 loops of use, 43.3˜47.5% of CO2 is captured with an initial amount up to 10 milli-moles per gram (mmol/g) and a stability ratio up to 91.2% maintained. | ||

| 主权项 | 1. A method of fabricating a pelletized medium-high-temperature carbon-dioxide (CO2) sorbent of calcium aluminum carbonate (Ca—Al—CO3), comprising steps of: (a) obtaining a powder of calcium aluminum carbonate (Ca—Al—CO3) by coprecipitation; and (b) mixing said powder of Ca—Al—CO3 with 1˜10 wt % of a release agent and 1˜10 wt % of a binder to obtain a pelletized carbon dioxide (CO2) sorbent through pelletization. | ||
