利用分子模拟方法研究了燃烧后CO2捕集溶剂的电离常数和氨基甲酸酯稳定常数。这两个平衡常数对于理解用于燃烧后碳捕获的任何溶剂的热力学非常重要。温度对这两个平衡常数的影响也研究了pKa的数据集的10种胺和10种氨基酸。还提供了MEA和DEA的氨基甲酸酯稳定常数的温度依赖性沿着与实验数据。
The ionization constants and carbamate stability constants for post combustion CO2capture solvents are in this work studied with the help of molecular modeling. These two equilibrium constants are very important in understanding the thermodynamics of any solvent for post combustion carbon capture. Temperature effects on these two equilibrium constants are also studied for pKa of a data set of 10 amines and 10 amino acids. Temperature dependency of carbamate stability constants of MEA and DEA along with experimental data is also presented.
