This study evaluated improvements in the CO₂ capture process in terms of cyclic capacity, absorption efficiency and heat duty caused by using a primary amine (5 M MEA) blended with a tertiary amine (2 M MDEA or 1.25 M DEAB) and a catalyst-aided desorber loaded with two different solid acid catalysts (γ-Al₂O₃ or HZSM-5) in a bench scale full cycle CO₂ capture plant. The absorber and desorber were stainless steel pipes with inside diameter of 0.05 m and height of 1.50 m. The desorber was loaded with varying amounts of solid acid catalyst at an average bed temperature of 85 °C. The two mixed amine solvents tested, were compared with 5 M MEA each with a circulation rate of 0.06 L/min. Simulated flue gas, 15% CO₂ in N₂, was used at a total flow rate of 15 SLPM. The results showed that in 5 M MEA system, cyclic capacity and absorption efficiency increased while heat duty decreased when the catalyst amount was increased. In the case of mixed primary and tertiary amines, catalysts contribute to slight improvements. The increase in absorption efficiency was found to be in the order of 5 M MEA: γ-Al₂O₃ < 5 M MEA: HZSM–5 < 5 M MEA: 2 M MDEA: γ-Al₂O₃ < 5 M MEA: 2 M MDEA: HZSM–5 < 5 M MEA: 1.25 M DEAB: γ-Al₂O₃ < 5 M MEA: 1.25 M DEAB: HZSM-5. The relative reduction in heat duty of the system was found to be in the order of 5 M MEA: 1.25 M DEAB: HZSM–5 < 5 M MEA: 2 M MDEA: HZSM–5 < 5 M MEA: 1.25 M DEAB: γ-Al₂O₃ < 5 M MEA: 2 M MDEA: γ-Al₂O₃ < 5 M MEA: HZSM-5 < 5 M MEA: γ-Al₂O₃.

这项研究评估了通过将伯胺（5 M MEA）与叔胺（2 M MDEA或1.25 M DEAB）混合并使用催化剂，在循环容量，吸收效率和热负荷方面对CO ₂捕集工艺的改进。辅助解吸器装载有两种不同的固体酸催化剂（在γ-Al ₂ ö ₃在一个实验室规模的全周期CO或HZSM-5）₂捕集设备。吸收器和解吸器是不锈钢管，内径为0.05 m，高度为1.50 m。在平均床温为85°C的条件下，解吸器装有各种量的固体酸催化剂。将两种测试的混合胺溶剂与5 M MEA进行比较，每种溶剂的循环速率为0.06 L / min。模拟烟气，15％CO ₂在N _2中，总流量为15 SLPM。结果表明，在5 M MEA体系中，随着催化剂用量的增加，循环容量和吸收效率增加，而热负荷降低。在混合伯胺和叔胺的情况下，催化剂有助于轻微改善。在吸收效率的增加被认为是在5M的MEA的顺序：在γ-Al ₂ ö ₃  <-5 M MEA：HZSM-5 <-5 M MEA：2M的MDEA：在γ-Al ₂ ö ₃  <-5 M MEA ：2M的MDEA：HZSM-5 <-5 M MEA：1.25M，DEAB：在γ-Al ₂ ö ₃ <5 M MEA：1.25 M DEAB：HZSM-5。发现系统的热负荷相对减少量约为5 M MEA：1.25 M DEAB：HZSM–5 <5 M MEA：2 M MDEA：HZSM-5 <5 M MEA：1.25 M DEAB：γ -Al ₂ ö ₃  <-5 M MEA：2M的MDEA：在γ-Al ₂ ö ₃  <-5 M MEA：HZSM-5 <-5 M MEA：在γ-Al ₂ ö ₃。
