The Alternating Growth of Bacteria within a Consortium During Desulfurization of Coal
Efforts to reduce organic sulfur in coal are taken through biodesulfurization by using desulfurization bacteria to release covalently-bound sulfur from the coal matrix. Coal is a complex hydrocarbon material that requires collaboration from more than one

Active-alkali metal promoted reductive desulfurization of dibenzothiophene and its hindered analogues [PDF]
Reductive desulfurisation of organic compounds is of importance both in organic synthesis and in industry. Benzo- and dibenzothiophenes are between the most abundant sulphur containing impurities in crude oils, and their desulfurization is a mandatory ...

One-pot cascade synthesis of dibenzothiophene-based heterobiaryls from dibenzothiophene-5-oxide
A one-pot protocol to access 4-substituted dibenzothiophene (DBT) from dibenzothiophene-5-oxide (DBTO) was developed via a sulfoxide directed C–H metalation/B2Pin2 mediated reduction/Suzuki coupling cascade process.

Three Novel Sets of Cs2H[PW4Mo8O40] Based on Various Supports: insight Into Comparative Evaluation in Oxidative Desulfurization [PDF]
Three novel heterogeneous catalysts were prepared by immobilization of a synthesized cesium salt of 4-tungsto-8-molybdophosphoric acid (abbreviated as CW4Mo8) on well prepared and modified support materials of UiO-66, microsphere SBA-15 and Graphene ...

Adsorption of thiophene, dibenzothiophene, and 4,6-dimethyl dibenzothiophene on activated carbons [PDF]
Four activated carbons (ACs) activated by different activation methods from different precursors were heat-treated at 600℃ to decrease surface oxygen functional groups and to separate the effect of pore texture from surface chemistry on their sulfur adsorption performance.
