Extraction and oxidative desulfurization of diesel fuel catalyzed by a Bronsted acidic ionic liquid at room temperature

, 2010
The Bronsted acidic ionic liquids 1-butyl-3-methylimidazolium hydrogen sulfate ([BMIM][HSO(4)]) and N-butylpyridinium hydrogen sulfate ([C(4)Py][HSO(4)]) were used as extractant and catalyst for desulfurization of diesel. The results show that [BMIM][HSO(

Oxidative desulfurization of model gasoline with ultrasound [PDF]

, 2015
Oksidacijska desulfurizacija je proces u kojem se sumporovi spojevi oksidacijom uklanjaju iz naftnih derivata. Sumporovi spojevi su nepoželjni jer su katalitički otrovi, vrlo su korozivni u brojnim procesima preradbe nafte i izgaranjem stvaraju ekološki ...

Machine learning–driven design of catalytic processes for sulfur dioxide oxidation: Lessons from the trenches

AIChE Journal, EarlyView.
Abstract Despite the growing use of ML in chemical engineering, the catalytic conversion of sulfur dioxide (SO2) to sulfur trioxide (SO3) remains underexplored from a data‐driven modeling perspective. This study evaluates an integrated workflow for literature‐derived SO2 oxidation data, combining data curation, preprocessing assessment, machine ...
