Summary: A combination of dual-frequency acoustic cavitation and UV assisted advanced oxidation processes was developed for desulfurization of raw naphtha. The hybrid process of acoustic cavitation/peracetic acid/hydrogen peroxide showed the most effective treatment with high desulfurization efficiency. The alternative treatment process of acoustic cavitation/UV/acetone/water achieved complete desulfurization of specific sulfur compounds.

Summary: Desulfurization is crucial in oil refining to mitigate the harmful effects of sulfur compounds. Naphtha, a key middle distillate, is extensively used as a fuel for automotive, engine, and jet-B applications. Hydrodesulfurization (HDS) is the conventional method employed to remove sulfur, but oxidative desulfurization (ODS) is gaining attention due to its mild reaction conditions and absence of hydrogen requirement. While ODS of diesel has been extensively investigated, limited studies have focused on ODS of naphtha. Understanding the challenges and optimizing ODS for naphtha, particularly in mini-refinery applications, is essential. This study comprehensively examines naphtha cuts, ODS mechanism, classification and comparative analysis of different ODS methods, various oxidants/catalysts, and kinetics of ODS reaction. Additionally, the impact of temperature, pH, catalyst content, and oxidation time on desulfurization efficiency is investigated, along with discussion on research gaps and suggestions for future studies in the field of ODS of naphtha.

Summary: The feasibility of steam gasification of tire char and the impact of various biomass ashes in the process were assessed. The addition of a catalyst and increasing its loading improved the reactivity of the tire-char and had a significant impact on gas component yields.

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 presence of sulfur hinders the clean utilization of coking coal. Inorganic sulfur, mainly in the form of pyrite, contaminates clean coal during flotation, while organic sulfur can only be effectively removed chemically. Desulfurization using a combination of flotation and oxidation methods reduces inorganic sulfur more efficiently than organic sulfur. The sulfur and ash content in coal were reduced from 2.55% and 46.16% to 1.33% and 13.41%, respectively, through the flotation-oxidation method. However, the oxidation-flotation method led to the formation of Fe2O3 on pyrite surfaces and increased the presence of oxygen-containing functional groups, adsorption capacity of water molecules, and hydrophilicity. MD simulation supported the experimental results, showing a lower diffusion coefficient of water molecules on the surface of oxidized coal compared to raw coal. This reduced the hydrophobicity of coal and resulted in lower product recovery compared to the flotation-oxidation method.

Summary: This study found that TDC showed notable catalytic capability due to the abundant acid sites on its surface, improving BTEX yield by 2.4 times compared to the uncatalyzed case. The loading of additional Zinc increased the acid sites on TDC and further improved catalytic performance. Increasing catalytic temperature and catalyst-to-tire ratio favored the formation of BTEX, but also caused undesirable consequences such as mass loss of tire pyrolysis oil and formation of polycyclic aromatic hydrocarbons.

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.
