摘要

为实现“双碳”目标，油田高含碳采出气的高效低能耗捕碳至关重要。选取6种醇胺：乙醇胺（MEA）、二乙醇胺（DEA）、2-氨基-2-甲基-1-丙醇（AMP）、N-甲基二乙醇胺（MDEA）、二乙氨基乙醇（DEEA）和三乙醇胺（TEA），通过

H NMR、

C NMR和FT-IR表征以及密度泛函理论（DFT）计算，系统研究了醇胺分子结构与CO

吸收性能、反应机理的关系。结果表明，在40 ℃、醇胺质量分数30%条件下，MEA与AMP的CO

饱和吸收容量较高（分别为2.72与2.58 mol/kg）。吸收CO

后醇胺液粘度增幅与胺种类密切相关，其中AMP富液粘度最大（20 °C时达8.11 mPa·s）。伯胺和仲胺与CO

反应遵循两性离子机理，而叔胺遵循碱催化水合机理。MEA与CO

两步反应（两性离子生成和质子转移步骤）的吉布斯自由能垒均最低（6.21 kJ/mol和5.03 kJ/mol），DEA与AMP因空间位阻影响，其速控步骤分别为质子转移（15.67 kJ/mol）和两性离子生成（8.70 kJ/mol）。MDEA、TEA和DEEA与CO

反应的吉布斯自由能垒分别为39.77 kJ/mol、42.04 kJ/mol和44.47 kJ/mol，显著高于伯仲胺。本研究可为后续高性能、低能耗混合胺吸收CO

体系的定向设计与开发提供可靠的理论依据。

Abstract

To achieve the “dual carbon” goals

the efficient and low-energy carbon capture of high-carbon content gas produced from oil fields is important. Six alkanolamines (monoethanolamine (MEA)

diethanolamine (DEA)

2-amino-2-methyl-1-propanol (AMP)

methyldiethanolamine (MDEA)

diethylethanolamine (DEEA) and triethanolamine (TEA)) were selected. By

H NMR

C NMR and FT-IR characterizations and density functional theory (DFT) calculations

the relationships between alkanolamine molecular structures

absorption performances and reaction mechanisms were systematically investigated. The results show that at 40 ℃ and alkanolamine mass fraction of 30%

MEA and AMP exhibit high CO

saturation absorption capacities (2.72 mol/kg and 2.58 mol/kg

respectively). The increase in viscosity of alkanolamine solutions after CO

adsorption strongly depends on the amine types

among which the viscosity of AMP-rich solution is the highest (8.11 mPa·s at 20 ℃). The reaction of primary and secondary amines with CO

follow the zwitterionic mechanism

whereas terti

ary amines follow base-catalyzed hydration mechanism. The Gibbs free energy barriers for both steps (zwitterion formation and proton transfer) in the two-step reaction between MEA and CO

are the lowest (6 .21 kJ/mol and 5.03 kJ/mol). Due to steric hindrance

the rate-determining steps of DEA and AMP are proton transfer (15.67 kJ/mol) and zwitterion formation (8.70 kJ/mol)

respectively. The Gibbs free energy barriers for reactions of MDEA

TEA

and DEEA with CO

are 39.77 kJ/mol

42.04 kJ/mol

and 44.47 kJ/mol

respectively

which are significantly higher than those of primary and secondary amines. This study can provide a robust theoretical framework to support the rational design and development of high-performance and low-energy-consumption hybrid amine absorption systems for CO

capture.
