Summary: Porous activated carbon was prepared from industrial coal sludge by one-step pyrolysis and KHCO3 activation and used for phenol removal from water. The activation parameters affected the characteristics of activated carbon and phenol adsorption. CSAC-900 exhibited abundant pores and a three-dimensional structure. The adsorption of phenol on CSAC-900 was controlled by various mechanisms, and the Langmuir model described the adsorption isotherm. The maximum adsorption capacity of phenol on CSAC-900 was 305.83 mg/g. The positive ΔH and negative ΔG indicated that the adsorption was spontaneous and endothermic. Compared to commercial activated carbon, CSAC-900 showed advantages in adsorption capacity and rate, and could be regenerated and recycled.

Summary: This study investigated the influence of textural properties of cotton-based activated carbon fiber (CACF) on benzene adsorption, revealing the impact of carbonization temperature, phosphoric acid embedment, and micropore characteristics on the adsorption performance of CACF. The results showed the importance of micropore surface area and volume for benzene adsorption, with a preference for adsorption in micropore walls rather than larger pores. Additionally, it was found that the affinity of CACF for benzene could unexpectedly improve with a decrease in micropore size.

Summary: Structured catalysts with different ceramic structures were utilized for the deposition of NiO-Al2O3 coatings in the oxidative dehydrogenation of ethane. Better catalytic performance was observed when cordierite monolith and alumina foam were used as substrates, resulting in higher ethylene selectivity values compared to the alumina-silica paper substrate. The addition of a second element like cerium led to an increase in ethane conversion but a decrease in ethylene selectivity, attributed to the generation of electrophilic oxygen species.

Summary: This study focuses on understanding the opportunities and limitations of sub-ambient CO2 capture processes using a multistage separation process, proposing a hybrid process design involving pressure-driven separation and CO2-rich product liquefaction. Among the considered sorbents, zeolite 13X fiber composites were found to perform better at ambient temperatures compared to sub-ambient, while MIL-101(Cr) and UiO-66 fiber composites showed improved purity, recovery, and productivity at colder temperatures, reducing costs of capture to as low as $61/ton CO2.

Summary: The chemical stability of metal-organic frameworks (MOFs) in water and acidic and basic solutions is well understood, but there is limited research on their stability in the presence of acid gases found in industrial settings. MIL-101-(Cr), a stable MOF in liquid water and acidic/basic solutions, was tested for its stability when exposed to sulfur dioxide (SO2) and nitrogen dioxide (NO2) gases. The breakthrough experiments and physisorption experiments showed that both gases reduce the adsorption capacity of MIL-101-(Cr). X-ray photoelectron spectroscopy (XPS) confirmed the presence of sulfur and nitrogen species in MIL-101-(Cr) after exposure to SO2 and NO2 gases. In situ infrared spectroscopy experiments revealed that SO2 adsorption in MIL-101-(Cr) is not fully reversible and NO2 adsorption causes structural degradation similar to observations in HKUST-1.
