Abstract

The
present work aimed to investigate the feasibility of removing sulfur from real light
gas oil using different types of inorganic ionic liquids (ILs) assisted by
ultrasonic waves in a continuous flow setup. Experimental results showed that
within 30 min, 66% of sulfur was removed under mild conditions using 10wt%NaOH assisted
by ultrasonic waves. It was found that ultrasonic waves not only facilitate the
sulfur removal but it improves gas oil properties by decreasing density and viscosity
while cetane number (CN) showed a different trend. A correlation of solute
selectivity as a function of sulfur mole fraction was presented 

Keywords
