High-Degree Oxidative Desulfurization of a Commercial Marine Fuel Using Deep Eutectic Solvents and Their Recycling Process

open access: yesSeparations, 2023
Escalating environmental concerns have dictated the need to develop innovative methods for efficiently desulfurizing marine fuels (heavy fuel oils). In this work, the oxidative desulfurization method using deep eutectic solvents (DESs) was applied to ...

Synthetic Strategies for Activity‐Based Probes to Decode Ubiquitin‐Like Modifiers

open access: yesChemistry – A European Journal, EarlyView.
ABSTRACT Ubiquitin‐like proteins (Ubls) such as SUMO, NEDD8, ISG15, URM1, UFM1, FAT10, ATG8/ATG12, and FUBI are essential regulators of cellular homeostasis, controlling processes from protein stability and trafficking to immune signaling and autophagy.

Synergistic Influence of Non-Thermal Plasma and Hydrogen Peroxide on Oxidative Desulfurization (ODS) of Model Fuel

open access: yesمجلة بغداد للعلوم
Desulfurization is the process of removing the organic sulfur component from fuel oils. In this work, model fuel containing the sulfur compounds benzothiophene and dibenzothiophene was oxidized using plasma technique and plasma technique assisted by 30%

Sonocatalytic Oxidative Desulfurization of Thiophene and Its Derivatives

open access: yesProcedia Engineering, 2012
AbstractCurrently, the sulfur level in diesels is limited to 10 and 15ppm in Europe and USA respectively, since the organosulfur compounds available in fuels emit corrosive SO2 gases into atmosphere during combustion, thus leading to acid rain. A lot of processes such as hydrodesulfurization (HDS), oxidative desulfurization (ODS) etc. have been used to

First Operation Results of a Methanol Demonstration Plant With Real Steel Mill Gases

open access: yesChemie Ingenieur Technik, EarlyView.
A demonstration plant with industrial setup regarding length, diameter, boiling water cooling system and gas recycle was initially operated with cleaned blast furnace gas and compared with earlier experiments with bottle gases. Dynamic disturbances from the steel mill and gas cleaning unit were noticed and could be compensated by the control system ...

Mixed‐Impurity Co‐Poisoning of NH3‐SCR Catalysts: Poisoning Mechanisms, Antagonistic Effects, and Anti‐Inactivation Strategies

open access: yesEcoEnergy, EarlyView.
This review summarizes the synergistic effects of mixed impurities on ammonia‐selective catalytic reduction (NH3‐SCR) catalysts, including the poisoning mechanism of the catalyst caused by mixed impurities, the antagonistic effects between the impurities, and the research on the anti‐poisoning strategies for the catalyst in recent years.

CO2‐Induced Reverse Lattice Oxygen Spillover on Pt/CeO2 Enables Sulfur‐Resistant Dry Reforming of Methane

open access: yesAngewandte Chemie, Volume 138, Issue 31, 27 July 2026.
A critical step, dry reforming of methane (DRM) converts biogas into useful syngas. Yet trace H2S in biogas rapidly poisons DRM catalysts, limiting practical use. We developed a robust Pt/CeO2 catalyst sustaining DRM activity via CO2‐induced reverse lattice oxygen spillover in H2S‐rich environments.

Low‐Temperature in Situ Upgrading of Ultra‐Deep Heavy Oil Using Ni–Ce/MOF–OTf Superacid Catalysts to Enhance Energy Utilization and Sustainability

open access: yesEcoEnergy, EarlyView.
A triflate‐functionalized Ni–Ce/MOF–OTf superacid enables low‐temperature (∼140°C) in situ upgrading of ultra‐deep heavy oil. It reduces viscosity by 92.11% in 12 h, maintains activity over cycles, and delivers 90.25% recovery with a lower carbon footprint by selective bond cleavage. ABSTRACT Ultra‐deep heavy oil is an important unconventional resource,

Toward a Paradigm Shift in Low‐Temperature SCR Catalyst Design: Defect Engineering and Data‐Driven Integration

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work systematically reviews the key factors influencing the performance of low‐temperature NH3‐SCR. The mechanism and challenges of defect engineering strategies, such as oxygen vacancies, heteroatom doping, crystal facet exposure, and surface reconstruction, in controlling both activity and selectivity were analyzed.
