The results of studies on distribution of microelements in the mixture of Azerbaijan oils and obtained from them atmospheric and vacuum gasoil fractions and residues boiling at different temperatures, are provided. These mixtures of oils will be used as raw materials in the new Oil and Gas Processing and Petrochemical Complex that will be built in the future. It is noted that the distribution of microelements in Azerbaijan oils and their residues have been studied by many researchers, but the distribution of microelements in distillate fractions is being studied for the first time. The presence of microelements in distillate fractions is explained by the fact that during distillation of the petroleum organo-metallic compounds disintegrate and get into fractions. In the investigated oils 9095 % of the metals are in the resins and asphaltenes, and their quantity in the fractions varies between 15 ppm. Since the number of resins in these samples is more than that of asphaltenes, it may be assumed that the largest portion of metals is in resins. Studying distribution of metals in oils, in their factions and residues is of a great importance in terms of finding solutions to a number of issues such as the genesis of oil, increasing the efficiency of technological processes of oil refining, as well as environmental issues.
