Nanostructured iron and nickel oxide aerogels revolutionizing asphaltene removal in hydrocarbon processing.

ABSTRACT: Asphaltenes, complex molecules in crude oil, cause significant challenges in oil production and refining due to their tendency to form agglomerates and precipitate. This study investigates the effectiveness of preparation method of metal oxide-based adsorbents (NiO and Fe₂O₃) in removing asphaltenes. Nanostructured NiO and Fe₂O₃ xerogels and aerogels were produced through the Pechini-type and epoxide-derived sol - gel methods and employed for the adsorption of Ap1, a specific asphaltene extracted from Iranian crude oil. The nanomaterials were characterized by XRD, N₂ adsorption-desorption, FE-SEM, EDS, and FT-IR. The influence of synthesis parameters, including citric acid to metal precursor molar ratio, type of adsorbent, textural cha
