Title:

硫酸消費量が低減された石油ストリームの窒素含量の低減法

Document Type and Number:

Japanese Patent JP2007513244

Kind Code:

A

Abstract:

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.
