Study of Radiation Effect on Petroleum Oils

The article provides the gas chromatographic results of decomposition products produced by radiation of the low - viscosity hydraulic oils. The analysis of radiation effect of different doses on model mixtures distinguishing by hydrocarbon composition allowed establish ing that hydrogen and hydrocarbon gases are the main components of the hydrocarbon radiation decomposition. The cycloalkane hydrocarbons subjected to dehydrogenation are the main hydrogen source under radiation exposure. The alkanes of different branching degree and alkane substituents of cycloalkanes serve as the hydrocarbon gas source. The arene structures have a stabilizing effect on the hydrocarbons regard to the radiation. It was shown that isoparaffinic hydrocarbons demonstrate the least degradation u nder action of radiation. The stabilizing effect of monocyclic aromatic hydrocarbons with branched alkyl substituents was confirmed.
