A facile synthesis of mesoporous Mo–Al oxides for desulfurization of dibenzothiophene in the extractive catalytic oxidative desulfurization system

Reaction Kinetics, Mechanisms and Catalysis, 2020
In order to obtain the deep desulfurization in the extractive catalytic oxidative desulfurization (ECODS) system, the evaporation-induced self-assembly (EISA) assisted by cash (combined assembly by soft and hard chemistry) method was applied to prepare mesoporous Mo–Al oxides with the stable catalytic performance when the acetonitrile as the extractant

Oxidative Desulfurization of Çayirhan Lignites by Permanganate Solution

Energy Sources, Part A: Recovery, Utilization, and Environmental Effects, 2008
Abstract Unless important developments record new and renewable energy sources, the role of fossil fuels as an energy resource goes on. It is possible to detect sulfur, heavy metals, and tracer elements such as arsenic and selenium by decreasing calorific value of coals.

Confined Heteropoly Blues in Defected Zr-MOF (Bottle Around Ship) for High-Efficiency Oxidative Desulfurization.

Small, 2020
The Keggin-type polyoxometalates (POMs) are effective catalysts for oxidative desulfurization (ODS) and confining these POMs in metal-organic frameworks (MOFs) is a promising strategy to improve their performances.

Oxidative desulfurization of benzene fraction on transition metal oxides

Russian Journal of Physical Chemistry A, 2013
It is established that molecular oxygen is able to oxidize thiophene selectively in a mixture with benzene on V2O5 · MoO3. The introduction of thiophene inhibits the oxidation of benzene. It is shown that the conversion of thiophene during operation of the catalyst is reduced at first and then increases until it reaches its initial value.

Highly efficient oxidative desulfurization of dibenzothiophene using Ni modified MoO3 catalyst

, 2020
Ni modified MoO3 (Ni-MoO3) had been synthesized by a facile one-step hydrothermal technique and was used for oxidative desulfurization (ODS) of dibenzothiophene (DBT) in the decalin/acetonitrile biphasic system with H2O2 as oxidant, the effect of ...

Polyoxometalate catalysis for oxidative desulfurization

2016
Oxidative desulfurization removes sulfur-containing molecules from petroleum feedstocks to upgrade the quality of fuels. It is driven by environmental legislation demanding very low sulfur levels in fuels. The oxidative desulfurization technology usually involves oxidation of sulfur-containing molecules with an appropriate oxidant, e.g.

Peroxide Oxidative Desulfurization of a Diesel Fuel

Theoretical Foundations of Chemical Engineering, 2018
The catalytic activity of transition metal compounds (Mo, V, and W) in the reaction of oxidative desulfurization of straight-run diesel fuel with hydrogen peroxide is studied. Oxidation with sodium molybdate decreases the total amount of sulfur in straight-run diesel by 43%, whereas the total amount of C20–C31 hydrocarbons is reduced from 87.4 to 83.6%.
