A Glimpse into the Molecular Journey inside an Ultralow Sulfur Diesel Reactor



Rapid advances in increasing the efficiency of the ultralow sulfur diesel (ULSD) process are hindered owing to the lack of realistic understanding that could be obtained by looking inside an operating ULSD reactor. Herein, quantitative information about the molecular journey of the sulfur, nitrogen, and aromatic compounds from the inlet to the outlet of a ULSD reactor has been provided. The improved understanding resulting from this work is expected to significantly assist catalyst development and mechanistic pathway determination efforts in this important area of research.
