摘　　要：钙基吸收剂循环煅烧／碳酸化法（CCRs）是捕集燃煤电厂烟气中CO2的一种潜在技术。利用双流化床反应器实现连续高效捕集烟气中的CO2是此技术应用到实际的关键。本文利用天然白云石，采用双鼓泡流化床反应器，连续捕集烟气中的CO2。试验结果表明，所采用的双流化床反应器可以实现两个反应器之间物料连续稳定地交换，并长时间连续高效捕集烟气中的CO2，捕集效率超过90％。Carbonation/calcination reaction cycles （CCRs） with Ca-based sorbents is a promising option for the CO2 capture from power plant flue gases. Interconnected fluidized bed reactors are the key technology to fulfill the CCRs process. The continuous CO2 capture experiment was carried out using an interconnected bubbling fluidized bed reactor with dolomite in this work. The experimental results indicated that the sorbent particles successfully circulated between the carbonator and the regenerator at high temperatures and the C02 in the flue gases was continuously captured by the Ca-based sorbent with the efficiency of above 90%.
