Summary: This study examines the feasibility of a novel cryogenic carbon capture method, where CO2 is deposited as frost onto a cold moving bed to continuously remove CO2. Experimental results show that frost front velocities range from 0.4 to 1 mm/s, enabling the design of a moving bed system for continuous capture. Conducted experiments demonstrate successful cryogenic carbon capture under moving bed conditions without frost accumulation.

Summary: This study presents a first-principle process simulation model for the chemical absorption of CO2 with MEA aqueous solutions using RPB. The model accurately simulates the phase and chemical equilibria, the heat and mass transfer, the reactions between MEA and CO2, and the RPB hydraulics. The reaction rate constant is found to be the controlling step with the greatest potential to enhance CO2 absorption performance in RPB.

Summary: This study investigates enhancing the separation performance of cellulose acetate (CA) by incorporating ionic liquid-like pendants. The experiments show that with increasing HEDMA content, the permeability of CO2 and N-2 decreases, while the selectivity of CO2/N-2 initially decreases and then gradually increases. This suggests potential for further improvements by altering interactions between the polymer network and permeating CO2 molecules.

Summary: Bicomponent nanofibers of cellulose acetate (CA) and polyethylene imine (PEI) were successfully fabricated using electrospinning technique for CO2 gas capture. The nanofibers were characterized and their morphology was studied using FT-IR, XRD, TGA, and SEM. The CO2 adsorption capacity of the nanofiber membranes was investigated and found to increase with higher PEI content and lower temperature. The CA/PEI electrospun membrane showed 99% retention of its initial CO2 adsorption capacity after 5 cycles of adsorption and desorption.

Summary: The study found that PAMAM dendrimer functionalized CNCs had higher CO2 capture capacity compared to bare CNCs and other derivatives, with CNC-G2 showing the best performance. The pseudo-second-order kinetic model provided a better fit to the adsorption kinetics, with an activation energy of 55.67 kJ/mol indicating dominant physisorption mechanism for CO2 capture. The FTIR spectra confirmed the formation of ammonium carbamate during CO2 capture, contributing to high tolerance of CO2 desorption under subsequent drier conditions.

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 paper investigates CO2 capture at room temperature and atmospheric pressure using a fluidized bed of Ca(OH)(2) powder, finding that an increase in relative humidity promotes CO2 capture, especially at near 100% RH. Quantitative analyses using X-ray powder diffractometry reveal that CaCO3 content in samples stored under high humidity originates from carbonation.

Summary: In this study, researchers used dry glass reference perturbation theory (DGRPT) and fully mutualized diffusion theory to predict the temperature and pressure dependent separations of complex liquid mixtures using SBAD-1 glassy polymer membranes. The results showed that the approach could accurately predict membrane-based separation of complex liquid mixtures over a wide range of temperature and pressure, using only single-component vapor sorption isotherms measured at 25 degrees C to parameterize the model. Furthermore, the model was successfully applied to predict the membrane separation of a light shale crude using a structure oriented lumping (SOL) based compositional model of petroleum, showing accurate prediction based on the trend of both molecular weight and molecular class.

Summary: Developing highly efficient bifunctional oxygen electrocatalysts is crucial for zinc-air flow batteries. Metal-organic frameworks (MOFs) and covalent organic polymers (COPs) have emerged as promising alternatives due to their designable and controllable atomic-level structures. However, their catalytic performances are limited by conductivity and catalytic activity. In this study, nanosheet FeNi-MOF and iron phthalocyanine rich COP hybrid materials are assembled through the pi-pi stacking effect to create highly efficient bifunctional electrocatalysts. The resulting catalyst exhibits superior catalytic performance and stability, making it a promising candidate for zinc-air flow batteries.

Summary: In this study, we modified the electrolyte cubic plus association equation of state (e-CPA EoS) and integrated it with two electrical conductivity models to estimate the electrical conductivity of 11 monovalent electrolyte solutions in water. The modified e-CPA model demonstrated better performance and the hybridization with electrical conductivity models resulted in two predictive models for estimating the electrical conduction of dilute and concentrated electrolyte solutions. These predictive models showed relative average percentage deviations (AARD) of 11.15% and 13.87% over wide ranges of temperature and electrolyte concentration.
