摘要
以负载型固体碳酸盐为吸附剂,采用流化床反应器对烟道气中二氧化碳的捕集进行了研究.测定了不同吸附剂、操作温度和反应时间对吸附效果的影响及吸附剂再生性能.结果表明,吸附剂为负载的固体碳酸钠,在65℃～85℃范围内,吸附时间为4min～10min,二氧化碳的脱除率达97.5%,吸附剂经过10次再生后达到稳定状态,可以长期使用.
At present the experimental study on carbon dioxide dry capture is mainly given priority to with mechanism, in industrialized device research has not seen the report. With supported solid carbonate as the adsorbent, the experimental study on carbon dioxide capture from flue gas is carried out with fluidized bed adsorption reactor. Experiment measured the effect on the adsorption of different adsorbent, temperature, reaction time, and adsorbent regeneration performance test. The results showed that the adsorbent is the solid sodium carbonate, in the range of 65℃-85℃. Moreover, absorption time is about 4 rain-10min. In this case, the removal rate of carbon dioxide can reach 97.5%, and adsorbent can reach steady state after 10 times regeneration, so adsorbent can use lone-term.
