The purpose of the present work is to explore the catalytic activity of locally available clays in petroleum fractions. The chemical analysis indicated mainly the presence of alumino-silicate dominance in the clay mineral composition. The major, minor and trace elements in clays were determined by employing X-ray Fluorescence (WD) and the mineral nature of clays were determined by IR spectroscopy. UVNisible spectrometry was employed to observe the concentration of naphthalene and benzene in gasoline of premium and naphtha brand. Clay sample no I and 2 showed the maximum catalytic reforming, whereas, sample no 4, 7 and 10 showed the maximum catalytic cracking. Sample no. 3, 5, 6, 8, and 9 showed no appreciable catalytic activity.
