Crude Oil Model Emulsion Characterised by means of Infrared Spectroscopy and Multivariate Techniques

Ti-MCM-48 mesoporous materials have synthesized by sequential addition of alkoxides. The atomic ratio of Si and Ti in the synthesis gel was 40 and 5, respectively. The materials were characterized by means of powder XRD, N2 adsorption-desorption measurements, HREM, (29)Si MAS NMR, diffuse reflectance FT-IR spectroscopy, electrophoretic mobility measurements and electron probe microanalysis.
