Summary: The esterification reactions between citric acid and lignin inhibit the formation of reactive intermediates in acid-catalyzed pretreatments. Adding citric acid to the pretreatment leads to higher cellulose recovery and lignin removal. Water content also plays an important role in the pretreatment and delignification process. The presence of citric acid improves enzymatic saccharification of cellulose by inhibiting repolymerization of degraded lignin fragments.

Summary: In this study, Coprinus comatus was found to effectively degrade lignocellulose in corn stalk. Various analyses, including scanning electron microscopy, specific surface area measurement, X-ray diffraction, Fourier infrared spectroscopy, and gas chromatography-mass spectrometry, were conducted to characterize the changes in corn stalk. The results showed that Coprinus comatus achieved a lignin degradation rate of up to 38.66%. The fungus eroded the structure of the corn stalk, forming pores that accelerated lignin degradation. Treated corn stalk exhibited increased specific surface area, reduced crystallinity, and the presence of small molecular substances. These findings demonstrate the effectiveness of Coprinus comatus for corn stalk degradation and suggest further investigation is needed to explore its potential in this field.

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.
