Comparison of an Industrial Adsorbent and Hybrid Materials for Direct Air Capture
The discourse on climate change is ubiquitous, prompting extensive research efforts by both the scientific and industrial communities. Carbon dioxide (CO2) is emerging as a key player in this challenge, as it is the primary contributor to the greenhouse effect by trapping heat in the atmosphere. Researchers in academia and industry recognize the need not only to design novel materials, but also to characterize them in detail.
For our benchmark material, we’ve chosen an amine-functionalized resin, specifically Lewatit® VP OC 1065, which was identified as a promising candidate for direct air capture back in 2012. Despite its advantages, Lewatit has drawbacks that necessitate the exploration of alternative materials to significantly improve process efficiency. Hybrid materials, exemplified by metal-organic frameworks (MOFs) or covalent organic frameworks (COFs), show considerable potential for direct air capture (DAC) processes due to their large specific surface areas and, in particular, their exceptional structural flexibility.
In this study, we perform a comprehensive comparison between the benchmark material and two hybrid counterparts. This comparative analysis begins with the acquisition of static manometric single-gas isotherms, which allow us to determine fundamental properties such as gas uptake, pore volume, pore size distribution, and heat of adsorption. Water isotherms are also recorded in recognition of the prevailing moisture in the atmosphere. However, industrial separation processes are typically dynamic, introducing various kinetic factors. Therefore, a complete characterization requires the acquisition of dynamic breakthrough curves.
Our laboratory is equipped with a special apparatus designed to collect dynamic adsorption data of various gas mixtures under humid conditions. This apparatus, tailored for small sample quantities (100 mg – 1000 mg), is ideal for method development and optimization. Materials can be tested under process-like conditions, and it also facilitates thermodynamic studies and cyclability investigations in an eco-efficient manner.
This set of experiments and methods is universally applicable to any porous material and serves to underscore the importance of thorough and reproducible characterization when evaluating potential candidates for CO2 capture.
