Summary: The study focuses on the sulfur removal from tire pyrolysis oil (TPO) by distillation and oxidation desulfurization process (ODS). A fraction of TPO with boiling point range of 190-350 °C, designated as TPO190-350 °C, was obtained by distillation. The sulfides in TPO190-350 °C were mainly benzothiophene derivatives. A POM-based catalyst was used in the ODS process to remove sulfur compounds from the oil, and it showed excellent catalytic performance and recyclability. The desulfurization efficiency of TPO190-350 °C was achieved up to 91.28%, reducing the initial sulfur contents from 11033 ppm to 961 ppm.

Summary: The consumption of fossil fuels has been increasing rapidly while tire degradation has been notably slower than tire disposal. Tire pyrolysis oil (TPO) produced through the pyrolysis process can be used as a substitute for fossil fuels and also accelerate tire degradation. Blending TPO with diesel can be a viable solution to address these issues.

Summary: An improved heat transfer model was developed in AVL-BOOST to enhance the efficiency of a diesel engine fueled with biodiesel, incorporating a five-component biodiesel skeletal mechanism. The model accurately predicted the engine's performance characteristics, with errors less than 2% between experiment and simulation. The nozzle diameter, injection pressure, and injection advance angle were found to be significant factors in the injection system, highlighting the need to choose the injection rate reasonably.

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.
