Abstract : The decomposition of fractions b.190, 210, 230, and 250C, respectively of light oil at high temp. and characteristics of reactions controlled to produce solid aromatic hydrocarbons and especially naphthalene were studied. The gas yield increases slowly with increasing temp. with a simultaneous decrease in the liq. fraction content. Unsaturated hydrocarbons undergo at high temp. condensation, polymerization, alkylation, and separation into coke. The properties of the basic oil change as a result of these reactions. The yield of unsaturated hydrocarbons increases at 750C. The styrene concentration remains stable at these temps., and even increases as a result of breaking up of side chains of benzene homologs.
