Thiophenic sulfur removal was attempted in three different modes of operation, such as
extraction, oxidation and simultaneous oxidation–extraction for a model fuel. Extraction was …

Liquid phase oxidation of thiophene in dodecane and subsequently extraction of the
oxidized product into a polar solvent were studied in continuous process, as a model for …

Removal of sulfur species from fuels is an increasingly critical environmental issue.
Hydrodesulfurization (HDS) removes sulfur compounds, such as mercaptans and sulfides …

Benzothiophene, Dibenzothiophene (DBT), 4-methyldibenzothiophene, and 4, 6-
dimethyldibenzothiophene are typical thiophenic compounds prevailing in diesel fuels …

Thiophene, benzothiophene, and dibenzothiophene were extracted from isooctane using
water and aqueous solutions of hydrochloric acid, sulfuric acid, nitric acid, acetic acid …

Thiophenes are the major sulfur compounds contained in transportation fuels, and the
removal of thiophenes dictates the degree of deep desulfurization of fuels. A new …

The thiophene extraction from model fuel by using N-methyl-2-pyrrolidone [NMP],
dimethylformamide [DMF] and ethylene glycol [EG] as solvents had been carried out at …

In a series of studies on precleaning technology based on sulfur forms, an advanced
desulfurization process that can be carried out under mild conditions has been developed …

An efficient extraction–oxidation catalytic system for deep desulfurization of a model fuel was
explored. First, Mo/γ-Al2O3 catalysts were prepared using an impregnation method and …

Thiophene is a commonly occurring sulfur compound in liquid hydrocarbon streams
produced in a petroleum refinery. The concentration of thiophene often needs to be reduced …
