In the present work, the distribution of these two groups of compounds over different fractions of crude oil was investigated. For this purpose two crude oil samples were separated in two steps: firstly, the asphaltenes were precipitated with n-heptane, and secondly, the maltenes were loaded on a silica column and eluted with solvents of increasing polarity. The four fractions of maltenes eluted from silica column were: F1, saturated and light aromatics; F2, polyaromatics; F3, resins; and F4, polar compounds. Fractions F1 and F2 were further investigated using gas chromatography, and all fractions were characterized by CHN analysis, confirming the increase of aromatics in the fractions 2, 3, 4 and asphaltenes. For the determination of Ni and V by ET AAS, oil-in-water emulsions were prepared. The speciation analysis was carried out measuring without chemical modifier (stable compounds) and with 20 g palladium (total Ni and V) and the volatile fraction was calculated by difference. The limits of detection were 0.02 g g−1 and 0.06 g g−1, for Ni and V, respectively, based on an emulsion of 2 g of oil in 10 mL. The volatile species of Ni and V were associated with fractions F3 and F4, while only thermally stable Ni and V was precipitated in part together with the asphaltenes.Submitted by JURANDI DE SOUZA SILVA (jssufba@hotmail.com) on 2012-07-11T13:23:53Z No. of bitstreams: 1 CONFIG~1...-S0039914007006418-main-1.pdf: 156391 bytes, checksum: 29ad9f2efe93a632d056b9740b0b4e70 (MD5)Made available in DSpace on 2012-07-11T13:23:53Z (GMT).
