摘　　要：基于粉煤灰矿化固定CO_2的捕集技术,本文提出了电石渣掺杂粉煤灰捕集CO_2的新技术。通过对模型化合物CaO和Ca(OH)_2吸附矿化CO_2的性能进行研究,然后采用电石渣掺杂粉煤灰进行矿化反应,并与纯粉煤灰反应效果作对比,验证了电石渣掺杂粉煤灰的可行性。该技术可提高粉煤灰的整体矿化效率。Based on the capture technology of CO2 mineralization sequestration by fly ash, a new technology of CO2 capture by calcium carbide slag doping fly ash was put forward in this paper. According to the study on adsorption and mineralization CO2 performance of model compounds CaO and Ca （OH） 2, then the mineralization reaction of carbide slag doping fly ash was tested and compared with the reaction effect of pure fly ash, the feasibility of carbide slag doping fly ash was verified. The overall mineralization efficiency of fly ash was improved through the technology.
