摘要

为降低直接空气碳捕集（Direct Air Capture

DAC）系统能耗，以搭载Lewatit 1065吸附剂的变温真空吸附（Temperature Vacuum Swing Adsorption

TVSA）反应器为研究对象，通过搭建一维非稳态传热传质仿真模型，对比回收吸附热和回收冷凝热策略在宽工况范围（5–45℃、25%–85%RH）内的能耗差异，拆解其构成与分析冷热供需特征。结果表明，回收冷凝热策略在大多数工况下具有更低的单位能耗，尤其在高湿工况（70%–85%RH）下表现出1.5 GJ/t以上的显著优势，回收吸附热策略仅在低湿工况（如25%RH）下表现出不高于0.65 GJ/t的能耗优势。两种策略的能耗差异是冷热供需、设备能效变化共同作用的结果。研究可为DAC系统热回收方案的场景化选型提供定量依据。

Abstract

Direct Air Capture (DAC) is a pivotal negative emission technology

yet its large-scale deployment is critically constrained by intensive energy consumption

particularly the thermal demand for sorbent regeneration. To mitigate this

this study focuses on a Temperature Vacuum Swing Adsorption (TVSA) system utilizing Lewatit 1065. A comprehensive one-dimensional unsteady-state model was developed to simulate the coupled heat and mass transfer dynamics within the adsorber. The model was employed to comparatively evaluate two distinct thermal integration strategies—adsorption heat recovery and condensation heat recovery—across a broad spectrum of ambient conditions (5–45℃

25%–85%RH). A granular energy audit was conducted to decompose the total energy consumption and analyze the supply-demand characteristics of heating and cooling. The results indicate that the condensation heat recovery strategy generally yields lower specific energy consumption than the adsorption heat recovery strategy under most operating conditions

demonstrating a significant advantage of over 1.5 GJ/t under high-humidity scenarios (70%–85%RH). Conversely

the adsorption heat recovery strategy only exhibits a marginal energy saving of no more than 0.65 GJ/t under low-humidity conditions (e.g.

25%RH). Crucially

the performance discrepancy between the two strategies is attributed to the combined effects of the dynamic heating and cooling supply-demand characteristics and the variation in the Coefficient of Performance (COP) of auxiliary equipment across the investigated range. This study elucidates the intrinsic energy coupling mechanisms within the TVSA process and provides a quantitative framework for the scenario-based selection of thermal management schemes in DAC system design.
