Beschreibung
Zusammenfassung:	The instant invention relates to a multi-stage process for producing low-nitrogen hydrocarbonaceous boiling range products involving contacting a hydrocarbonaceous feedstream with an acidic solution to selectively remove heterocyclic nitrogen-containing compounds, recovering the used sulfuric acid solution, and cascading the used sulfuric acid solution to another downstream contacting stage.
