Abstract	Authors describe the synthesis of a new sorbent material for desulfurization of gasoline, which is composed of polyimide (PI) and vanadium pentoxide via the solution direct-dispersing method. Researchers prepared the highly porous PI–V2O5 hybrid materials, containing various concentrations of V2O5 ranging from 1 to 10 wt%, from pyromellitic dianhydride, 2,4,6-triaminopyrimidine, and vanadium pentoxide. They examined the effect of V2O5 on the sulfur removal properties as well as the thermal stability and porous structure of composites. They studied the resulting material to ascertain their sorption characteristics for sulfur compounds from fuels. Using this material, 91 wt% of the sulfur content was removed from sulfur-containing standard oil. An economic sensitive and simple method for the removal and separation of sulfur in fuel samples, using an PI–V2O5 packed mini chromatographic column, was established.
