In this study, the heats of absorption of CO₂ in aqueous benzylamine (BZA), N-(2-aminoethanolamine) (AEEA), and their blends were measured using an automated reaction calorimeter in the temperature range of 303.15–343.15 K. The experimental concentrations of aqueous amine solutions were in the range of (0.49–4.0) mol BZA·kg^–1 water, (0.51–4.11) mol AEEA·kg^–1 water, (2.03 mol BZA + 2.09 mol AEEA)·kg^–1 water, and (2.71 mol BZA + 1.39 mol AEEA)·kg^–1 water. The heat capacities of the unloaded aqueous solutions of BZA, AEEA, and (BZA + AEEA) were also measured in similar temperature and concentration ranges to those for heat of absorption. The experimental heat of absorption of CO₂ was presented as a function of CO₂ loading, temperature, and amine concentration.

使用反应量热仪测量苄胺，N-（2-氨基乙基）-乙醇胺及其混合物的水溶液中吸收CO2的热量和热容

在这项研究中，使用自动反应量热计在303.15–343.15 K的温度范围内测量了苄胺水溶液（BZA），N-（2-氨基乙醇胺）（AEEA）及其混合物中CO ₂的吸收热。胺水溶液的实验浓度范围为（0.49–4.0）mol BZA·kg ^–1水，（0.51–4.11）mol AEEA·kg ^–1水，（2.03 mol BZA + 2.09 mol AEEA）·kg ^–1水，以及（2.71 mol BZA + 1.39 mol AEEA）·kg ^–1水。在与吸收热相似的温度和浓度范围内，还测量了BZA，AEEA和（BZA + AEEA）的未负载水溶液的热容量。实验性吸收CO的热量_图2表示为CO ₂负载量，温度和胺浓度的函数。
