Summary: This study focused on the synthesis and application of activated carbon in removing DBT and DMDBT from isooctane, showing that the adsorbent synthesized from agricultural waste material exhibited high surface area and porosity. DFT calculations predict the selectivity of the activated carbon towards DMDBT, with results indicating that DMDBT preferentially adsorbs onto adsorbents with larger pore sizes and volumes. Thorough studies on the adsorbent's performance in removing organosulfur compounds revealed that process parameters such as pyrolysis temperature and ramping rate play crucial roles in determining the adsorbent's efficiency.

Summary: This study compared the performance of potassium permanganate-modified bamboo biochar (MBB) with unmodified bamboo biochar (BB), activated carbon, and manganese greensand in adsorbing manganese from simulated groundwater. The results showed that the Langmuir model was the best fit for manganese adsorption by MBB and BB, with maximum adsorption capacities of 21.277 and 0.803 mg g(-1), respectively. The heat of adsorption from the Temkin model indicated that manganese adsorption occurs via an ion exchange process for MBB and a physical adsorption process for BB.

Summary: Biochars derived from agricultural wastes were modified by manganese ferrite (MnFe2O4) co-precipitation and used as adsorbents for the removal of Cu(II) ions from water. The MnFe2O4-biochars exhibited rapid adsorption kinetics and significantly enhanced adsorption capacities. Complexation reactions involving carboxyl and hydroxyl groups in pristine biochars, as well as Mn-O and Fe-O groups in MnFe2O4-biochars, were identified as the principal adsorption mechanisms. The regenerated MnFe2O4-biochars could be reused for three cycles with a decline in maximum adsorption capacities.

Summary: The study shows that NaY modified with ammonium nitrate and citric acid increases the adsorption capacity of thiophene in simulated coke oven gas. On medium-strong Bronsted acid sites, thiophene polymerization reaction occurs easily, leading to a significant decrease in Q(b-thiophene) due to acid sites covering and micropores blocking. The increase of Lewis acid is beneficial to desulfurization and provides a wider temperature region for thiophene removal compared to Bronsted acid.

Summary: In this study, NaY-zeolites were modified by combining Cu ion-exchange and Na2O or CuO impregnation for adsorptive desulfurization. The results showed that Na2O promoted the adsorption of TBM, while CuO inhibited it. Among the tested samples, the Cu ion-exchanged Y-zeolite containing Na2O showed the most efficient adsorption performance with a 3.97 wt% uptake for TBM, which is 30% higher than that of the Cu ion-exchanged Y-zeolite. The Cu ion-exchanged Y-zeolite containing CuO showed the lowest adsorption ability with a 2.21 wt% uptake for TBM.

Summary: In this study, a hybrid structure, MIL-53(Al)@MWCNT, was synthesized by combining MIL-53(Al) particles and -COOH functionalized multi-walled carbon nanotube (MWCNT). The hybrid structure was then embedded in a polyethersulfone (PES) polymer matrix to prepare a mixed matrix membrane (MMM) for CO2/CH4 and CO2/N2 separation. The addition of MWCNTs prevented MIL-53(Al) aggregation, improved membrane mechanical properties, and enhanced gas separation efficiency.

Summary: Non-conventional amines are being researched worldwide to overcome the limitations of traditional amines like MEA and MDEA. Adequate process and thermodynamic models are crucial for understanding the applicability and performance of these amines in CO2 absorption, but studies on process modeling for these amines are limited. This study used rate-based modeling and Deshmukh-Mather method to model CO2 absorption by DETA solution in a packed column, validated the model with experimental data, and conducted a sensitivity analysis of mass transfer correlations. The study also compared the CO2 absorption efficiency of DETA solution with an ionic solvent [bmim]-[PF6] and highlighted the importance of finding optimum operational parameters for maximum absorption efficiency.

Summary: The utilization of smart water in EOR operations has gained attention, but more research is needed to understand the complex mechanisms involved. This study investigated the interfacial tension between smart water and crude oil, considering factors such as salt, pH, asphaltene type, and aged smart water. The results revealed that the hydration of ions in smart water plays a key role in its efficacy, with acidic and basic asphaltene acting as intrinsic surfactants. The pH also influenced the interfacial tension, and the aged smart water's interaction with crude oil depended on asphaltene type, salt, and salinity.

Summary: In this study, high-performance solid catalysts based on phosphotungstic acid (HPW) supported on Zr-SBA-15 were synthesized and evaluated for the one-pot conversion of furfural (FUR) to γ-valerolactone (GVL). The catalysts were characterized using various techniques, and the ratio of HPW and Zr was found to significantly affect the selectivity of GVL. The HPW/Zr-SBA-15 (2-4-15) catalyst exhibited the highest GVL yield (83%) under optimized reaction conditions, and it was determined that a balance between Bronsted acid sites (BAS) and Lewis acid sites (LAS) was crucial for achieving higher catalytic performance. The reaction parameters and catalyst stability were also investigated.
