Summary: A new methodology for evaluating commercial adsorbents for CO2 capture using temperature swing adsorption has been developed. The study found that binderless zeolites performed better in CO2 production and desorption energy compared to their binder-based counterparts. The 13XBL binderless zeolite had the highest CO2 production and lowest desorption energy, while the 5A zeolites had the lowest CO2 production and highest desorption energy among the zeolites.

Summary: Environmental pollution is a serious issue, particularly due to fossil fuel pollution increasing atmospheric CO2 levels. The use of carbon capture and storage technologies, as well as adsorption techniques with carbon materials, show promise for addressing this issue. Factors such as micropore volume, surface area, and introduction of basic functional groups play crucial roles in CO2 adsorption.

Summary: Experimental and modeling analysis shows that using packed open-cell foams as an alternative to standard packed bed configuration can achieve faster temperature transitions and reduce temperature gradients within the adsorption bed. Even though there is a loss of sorbent inventory with the presence of foam, higher process productivity is achieved due to faster temperature swings and more homogeneous temperature distribution within the adsorption columns.

Summary: This article reviews the properties of zeolites as CO2 adsorbents and critically presents and discusses their advantages and limitations. Firstly, an overview of the CO2 adsorption mechanisms on different types of zeolites is provided. Then, the relationship between the physicochemical properties of zeolites (framework type, Si/Al ratio, and extra-framework cations) and their performance as CO2 adsorbents for the separation of CO2/CH4 (biogas) and CO2/N2 (flue gas) mixtures is systematically discussed. Based on the identified trends and properties, a comparison of different zeolites is made, highlighting their advantages and drawbacks for CO2 adsorption. Finally, the state of the art in the shaping of zeolites in macroscopic format, which is crucial for their industrial utilization as adsorbents, is presented.

Summary: A process for carbon capture from limestone calcination in a steam atmosphere generated by hydrogen and oxygen combustion has been developed. This process allows for carbon dioxide capture by condensing steam from exhaust gases, eliminating the energy-intensive step of carbon dioxide separation. A techno-economic analysis shows that cost parity can be achieved once the price of hydrogen reaches a certain range.

Summary: A reaction-diffusion shrinking core model is used to describe the decay in diffusivity of supported amine sorbents upon CO2 sorption. The decay is caused by crosslinking and pore blockage, which occur as CO2 is adsorbed. Four kinetic parameters governing CO2 uptake kinetics and working capacity are obtained from the model. The kinetic performance is correlated to the dispersion of sorption sites and morphology of the active sorbent phase. This work provides a first principles kinetic analysis of CO2 sorption, improving upon previous semi-empirical models.

Summary: This study investigated the effect of H2S concentration in biogas on H2 production through the sorption enhanced steam reforming (SESR) process. The results showed that the catalyst activity was not affected at low H2S concentrations during the SESR cycles, but there was a slight decrease in catalyst activity at higher H2S concentrations. Sulfur was detected in both the catalyst and sorbent materials, with a higher proportion in the sorbent at higher H2S concentrations. H2 yield and purity decreased after the SESR cycles, especially at higher H2S concentrations.
