【摘要】 提出了固体氧化物燃料电池零排放新思路设计,该设计具有高发电效率、温室气体零排放、回收利用二氧化碳以及使用环境友好的可再生循环二氧化碳吸收材料等优点。对新型二氧化碳吸收材料的吸附性能进行了研究。结果表明:最大体积吸收比可高达993倍.最佳吸收温度为700℃。同时可实现在800℃以上2 h内将所吸附的二氧化碳完全解析。通过电子扫描显微镜观察到材料吸附二氧化碳后变得疏松多孔,说明这一现象是有利于二氧化碳气体的吸收。更多还原

【Abstract】 A new concept of zero emission for solid oxide fuel cell system was proposed, which has some advantages such as high power generation efficiency, zero emission of greenhouse gas, carbon dioxide recycling, and reusable material with environmental benign for carbon dioxide capture. The capture ability of carbon dioxide for reusable material Li4SiO4 was reported and emphasized. The maximum volume absorption ratio could be 993 and the optimum capture temperature is 700 C for new absorption material, and carbon dioxide captured could desorb completely if the temperature is higher than 800℃ in 2 h. The porous structure of samples reacted was observed via SEM images, which indicates this phenomenon could enhance reaction rate of CO2 absorption.更多还原
