To accelerate the deployment of Carbon Capture and Storage (CCS) based on the solid amine adsorbents towards a practical scale application relevant to Natural Gas Combined Cycle (NGCC) power plants, this study has evaluated the cyclic performance of a polyethylenimine/silica adsorbent of kg scale in a laboratory scale bubbling fluidized bed reactor. A high volumetric concentration 80−90 vol% of steam mixed with N₂ and CO₂ has been used as the stripping gas during a typical temperature swing adsorption (TSA) cycle. Both the simulated NGCC flue gas and the actual flue gas from a domestic gas boiler have been used as the feed gas of the CO₂ capture tests with the solid adsorbent. Various characterization has been carried out to elucidate the possible reasons for the initial capacity decline under the steam regeneration conditions. The effect of presence of CO₂ in the stripping gas has also been studied by comparing the working capacities using different regeneration strategies. It has been demonstrated that the breakthrough and equilibrium CO₂ adsorption capacities can be stabilized at approximately 5.9 wt% and 8.6 wt%, respectively, using steam regeneration for both the simulated and actual natural gas boiler flue gases. However, using a concentration of 15 vol% CO₂ in the stripping gas has resulted in a significantly low working capacity at a level of 1.5 wt%, most likely due to the incomplete CO₂ desorption and degradation in a CO₂ containing environment.

为了加快基于固体胺吸附剂的碳捕集与封存（CCS）的部署，以实现与天然气联合循环（NGCC）电厂有关的实际规模应用，本研究评估了千克重的聚乙烯亚胺/二氧化硅吸附剂的循环性能在实验室规模的鼓泡流化床反应器中进行规模化处理。在典型的变温吸附（TSA）循环中，高体积浓度的80-90 vol％的蒸汽与N ₂和CO ₂混合在一起已用作汽提气。NGCC的模拟烟气和家用燃气锅炉的实际烟气均已用作CO ₂的进料气用固体吸附剂进行捕获测试。已经进行了各种表征以阐明在蒸汽再生条件下初始容量下降的可能原因。通过比较使用不同再生策略的工作能力，还研究了汽提气中CO ₂的存在的影响。已经证明，对于模拟的和实际的天然气锅炉烟道气都使用蒸汽再生，突破和平衡的CO ₂吸附能力可以分别稳定在大约5.9wt％和8.6wt％。但是，使用15 vol％的CO ₂浓度汽提气中的CO ₂导致工作能力明显降低，为1.5 wt％，这很可能是由于CO ₂的不完全解吸和在含CO ₂的环境中的降解。
