Desulfurization of Benzothiophene Derivatives by Solvent Extraction Coupled With Oxidation Using Oxomolybdenum(VI) Bis(pyrazolyl)methane Catalysts

European Journal of Inorganic Chemistry, Volume 29, Issue 13, 1 May 2026.
A polymeric hybrid material formulated as [MoO3(bis(pyrazolyl)methane)] has been prepared and used as a catalyst precursor for the complete oxidative desulfurization of a model diesel containing recalcitrant benzothiophene derivatives. The precursor is converted in situ to an oxodiperoxo active species which is retained in the recyclable extractant ...

Nonthermal Plasma Regeneration of Coke‐Deactivated Catalysts Used for Plasma‐Catalytic VOC Removal

Plasma Processes and Polymers, Volume 23, Issue 4, April 2026.
The research focused on the regeneration of coke‐deactivated catalysts previously used for plasma‐catalytic toluene removal from the air. Three regeneration techniques (plasma, ozone and thermal) were compared. The plasma regeneration showed the highest efficiency in removing the coke deposits, whereas the effect of ozone and heat was negligible ...

Acid Modification of the Unsupported NiMo Catalysts by Y-Zeolite Nanoclusters

Crystals, 2019
Unsupported NiMo catalyst has high hydrogenation activity due to its high active site distribution. However, low specific surface area and pore distribution greatly limit the efficient utilization of the active components. The Y-zeolite nanoclusters were

Adsorption Desulfurization of Liquid Fuel Using a Blend of Date Stones and Walnut Shells by Box–Behnken Design

Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 2, March/April 2026.
ABSTRACT A specific microporous KOH/activated‐biochar (K/BC) was produced from a blend of date stones (DS) and walnut shells (WS) and used in the adsorptive desulfurization (ADS) of two types of model fuel DBT/n‐hexane (S‐hex), DBT/cyclohexane (S‐cyclohex).

Olefin separation from FCC naphtha by deep eutectic solvents: PC‐SAFT modeling and molecular insights

AIChE Journal, Volume 72, Issue 2, February 2026.
Abstract Olefin extractive separation from fluid catalytic cracking (FCC) naphtha with deep eutectic solvents (DESs) was systematically investigated in this work. In a first step, different DESs were screened for their separation performance of the binary mixture benzene/1‐hexene.
