The　extraction　of　trace　polar　compounds,　among　them　neutral　nitrogen-containing　compounds　(N-compounds),　has　received　much　attention　from　refiners　because　of　their　inhibiting　effect　on　the　hydrodesulfurization　(HDS)　process.　Recently,　we　have　shown　that　chloride-based　ionic　liquids　(ILs)　can　selectively　extract　N-compounds　from　straight-run　diesel　feeds.　However,　the　measurable　solubility　of　ILs　in　hydrocarbon　fuel　is　not　a　desired　outcome　of　the　process.　Thus,　the　covalent　binding　of　ILs　moieties　on　polymers　was　studied.　Starting　from　Merrifield　resin,　three　resins　were　prepared　with　imidazolium,　pyridinium,　and　triethylammonium　chloride　functionality.　The　resins　were　evaluated　using　a　synthetic　solution　with　dibenzothiophene　and　carbazole　as　model　compounds,　and　a　high　selectivity　for　N-compounds　was　found.　Imidazolium　and　pyridinium　resins　were　then　further　evaluated　using　straight-run　diesel　feed　containing　13400　ppm　S　and　105　ppm　N.　The　selectivity　toward　N-compounds　was　comparable　to　the　selectivity　observed　with　ILs.　Moreover,　the　resins　could　be　easily　regenerated　using　a　protic　solvent　like　methanol.　©　2009　American　Chemical　Societ.
