COMPARISON OF EXPERIMENTAL AND MODELLED DATA FOR SULFUR MOLECULAR DISTRIBUTION IN DIESEL FEEDS FROM VARIOUS ORIGINS

摘要

The clean fuel legislation in the EU and USA has brought stricter limitations requiring a total sulfur content in gasolines and diesel oils around 10 ppm after 2008.Advances in hydrotreatment and hydrocracking technologies over the last decades have improved the removal of sulfur from refined products such as diesel oils.However,some organic sulfur compounds are known to be refractory towards hydrodesulfurization pathways,especially alkylated dibenzothiophenes.Therefore,the molecular identification and quantification of sulfur compounds is a fundamental requirement to the understanding of reactions involved in sulfur removal from diesel feeds.
