The adsorption of model naphthenic acid such as hexanoic acid, benzoic acid and commercial naphthenic acid from dodecane/kerosene was also investigated. The silica supported ionic liquids are good adsorbent for the removal of naphthenic acid from highly acidic model oil. The regeneration of supported ionic liquid phases as well as recovery of naphthenic acids from the supported ionic liquid phases (SILPs) was investigated. © 2015 by De Gruyter. publisher: Walter de Gruyter GmbH date: 2015 type: Article type: PeerReviewed identifier: Shah, S.N. and Lethesh, K.C. and Abdul Mutalib, M.I. and Mohd Pilus, R.B.
