The overall objective of this project is to explore a new desulfurization system concept,
which consists of efficient separation of the refractory sulfur compounds from diesel fuel by …

The need for cleaner fuels in term of low sulfur content is becoming a very challenging task
to most of the refineries. This is due to the stringent environmental regulations which are …

Sulfur compounds represent one of the most common impurities present in the crude oil.
Sulfur in liquid fuel oil leads directly to the emission of SO2 and sulfate particulate matter …

Sulfur content of diesel fuel has been cut down to ultra low levels by environmental
regulation in many countries with the aim of reducing diesel engine's harmful emissions and …

This review discusses the problems of deep desulfurization of transportation fuels and
presents an overview of new technologies and emerging catalyst or sorbents for ultra-deep …

Deep hydrodesulfurization (HDS) of diesel fuel oil was designed based on the recognition
that alkyl dibenzothiophenes such as 4-methyl-and 4, 6-dimethyldibenzothiophenes were …
