Summary: This study measured and modeled the adsorption behavior of CO2 in shale formations, providing baseline values for carbon sequestration planning. The experimental program involved extracting extractable components from shale using supercritical CO2. The results showed that the total organic carbon content of the shale was the primary factor determining CO2 adsorption and provided useful knowledge for future gas extraction and sequestration projects.

Summary: Analytic expressions for isosteric heats of adsorption are derived for commonly used isotherm models and a two-dimensional molecular equation of state based on the SAFT-VR approach. The predicted isosteric heat of adsorption exhibits strong variations in regions where experimental data is insufficient.

Summary: This study proposed two composite models for shale gas adsorption which showed better fitting effects at low pressures. The research also revealed that filling of micropores hardly occurs in the competition of two adsorption modes, and changes in adsorption heat and entropy depend on this competition.

Summary: In this study, a series of hyper-cross-linked polymers of intrinsic microporosity (PIMs) with high CO2 uptake and good selectivity were designed, synthesized, and characterized. The functionalization of the starting hydrocarbon polymers led to improved adsorption selectivity towards CO2. The insertion of functional groups resulted in a decrease in porosity but an increase in CO2 uptake and selectivity. The findings have significant implications for carbon capture and biogas upgrading.

Summary: Understanding the gas sorption behavior of coals, different adsorption models, and the interaction between pore surface and CH4 molecules at different relative pressures are crucial for enhancing coalbed methane recovery. The isosteric heat and ultimate heat of CH4 adsorption in various rank coals were analyzed, showing a positive correlation with micropore surface area. This research may provide insights for the process of CH4 adsorption in coals.

Summary: Metal organic frameworks (MOFs) are promising materials for achieving cooling, heating, and water desalination with zero or negligible carbon footprint. This article investigates the water adsorption and desorption characteristics of different functional group-assisted MOFs in the adsorption heat transformation (A-HT) process, and evaluates their performance in terms of cooling, heating, and desalination capacities.

Summary: Nitrogen-doped carbonaceous adsorbents with high ultra-microporous structure were successfully synthesized in this study, showing the highest CO2 adsorption value at 700 degrees C due to the synergistic effect of nitrogen, high specific surface area, and micropore volume. The heterogeneous nature of the adsorbent, along with a strong interaction between the adsorbent and adsorbate, contributed to the high CO2 uptake efficiency.

Summary: The stoichiometry of hexacyanoferrate materials affects their porosity properties and CO2 capture applications. Varying amounts of Co ions and oxidation states of transition metals affect the structures of mesoporous K or Na-cobalt hexacyanoferrates (CoHCFs) and CO2 removal. The results demonstrate that CoHCFs have practical implications in CO2 capture and flue gas separations.

Summary: This study analyzed the effects of temperature and physical parameters on adsorption capacity in the Lower Cambrian Niutitang Formation shale in northern Guizhou Province, China. A new adsorption model with two physical meaning parameters was constructed and validated. The study also calculated the isosteric enthalpy of adsorption in the shale and discussed the factors affecting it. The results showed that the isosteric enthalpy decreased with temperature increase and increased with an increase of TOC. A new method to predict adsorption isotherms at different temperature conditions was provided, yielding better prediction results. This study provided new insights into the thermodynamic characteristics of shale adsorption.

Summary: This review focuses on the recent progress of nanoporous adsorbents developed for light hydrocarbon separation, which is classified into acetylene separation, alkene/alkane separation, and propyne separation. Adsorptive separation is considered a promising technique with lower energy consumption than conventional processes.

Summary: Metal organic frameworks (MOFs) are widely used in adsorption and separation due to their porous nature and high surface area. In this study, hydrogen adsorption in four copper MOFs was analyzed using molecular simulation. The results showed that PCN-60 exhibited high hydrogen uptake at both 298 K and 77 K.

Summary: The adsorption mechanism of ethanol on graphite was comprehensively investigated using experimental measurements and computer simulation. The study highlights the unique interplay of clustering and molecular layering of ethanol. Ethanol exhibits intermediate characteristics between simple gases and water during adsorption. The mechanism of ethanol adsorption involves the formation and growth of discrete clusters, predominantly in the form of tetramers and pentamers, followed by the coalescence of growing clusters. The interplay of clustering and coalescence depends on temperature.

Summary: This study investigated hydrogen adsorption on six commercial activated carbons under different temperature and pressure conditions. The authors found that the use of nonlocal density functional theory provided a more accurate prediction of hydrogen adsorption capacity. The relationship between hydrogen adsorption capacity and surface properties of activated carbons was established, and different parameters were identified for evaluating the best activated carbon for hydrogen storage or compression.

Summary: The study found that layer-by-layer assembled carbon nanotube coatings can enhance dropwise condensation heat transfer under steam-air mixture conditions, with further improvement in condensation heat transfer coefficient by adding a hydrophobic coating. A new HTC model incorporating constriction resistance was developed to better predict the measured condensation HTC.

Summary: This work investigates the impact of nitrogen doping on the porous structure and CO2 adsorption properties of carbon foams. Different carbon foams are prepared with varying nitrogen contents using different amino alcohols. The results show that nitrogen species and ultra-micropores contribute positively to CO2 uptake, and the nitrogen-doped carbon foam displays higher CO2 adsorption than the undoped carbon foam reference.
