使用固体吸附剂的直接空气捕获 (DAC) 作为一种二氧化碳去除 (CDR) 技术已受到广泛关注，有助于将全球气温上升限制在 2 °C 以下。开发新的 DAC 吸附材料是一大重点领域。然而，在吸附剂筛选过程模型中使用这些材料所需的必要数据很少可用。在这里，我们展示了 Purolite A110，一种市售的胺官能化聚合物树脂，作为 DAC 的新候选吸附剂，并将其性能与当前基准 Lewatit VP OC 1065 进行比较。对于这两种材料，我们报告了它们的化学特征和成分、骨架、颗粒和床密度、总孔体积、颗粒孔隙率、BET 面积、热稳定性和比热容。我们通过测量 288、298、308、333、343、353 和 393 K 的体积 CO ₂等温线、288、298 和 308 K 的 N ₂和 H ₂ O 等温线以及 Ar 和 O 来确定它们的平衡吸附特性。在298 K 处有_{2 条}等温线。对于CO ₂ 、N ₂和H ₂ O，我们还给出了相应的等温线模型拟合参数和吸附热。这些数据可以帮助促进过程建模和优化研究，以正确大规模地评估这些吸附剂。

Measurement of Physicochemical Properties and CO2, N2, Ar, O2, and H2O Unary Adsorption Isotherms of Purolite A110 and Lewatit VP OC 1065 for Application in Direct Air Capture

Direct air capture (DAC) using solid adsorbents has gained significant attention as a carbon dioxide removal (CDR) technology to help limit global temperature rise to below 2 °C. One large area of focus is the development of new adsorbent materials for DAC. However, the necessary data needed to employ these materials in process models for adsorbent screening are rarely available. Here, we showcase Purolite A110, a commercially available amine-functionalized polymeric resin, as a new candidate adsorbent for DAC and compare its properties to a current benchmark, Lewatit VP OC 1065. For both materials, we report their chemical features and composition, skeletal, particle, and bed density, total pore volume, particle porosity, BET area, thermal stability, and specific heat capacity. We determine their equilibrium sorption properties by measuring the volumetric CO₂ isotherms at 288, 298, 308, 333, 343, 353, and 393 K, N₂ and H₂O isotherms at 288, 298, and 308 K, and Ar and O₂ isotherms at 298 K. For CO₂, N₂, and H₂O, we also present the corresponding isotherm model fitting parameters and heats of adsorption. These data can help facilitate process modeling and optimization studies to properly assess these adsorbents at scale.
