SYNTHESIS OF SYNTHETIC PETROLEUM ACIDS BASED ON NAPHTHENE-PARAFFINIC CONSENTRATE IN THE CATALYTIC PRESENCE OF REDUCED GRAPHENE OXIDE

The aerobic oxidation of naphthene-paraffinic fractions were derived from a mixture of Azerbaijan oils were firstly conducted. The various modifications of reduced graphene oxide (RGO) were used in petrochemical synthesis as a catalyst for the reduction reaction at first time. The basic parameters affected by the process were identified. The effect of the reaction medium effected on the structure of RGO was discussed in detail. The dependence of the yield of petroleum acids was also investigated for the catalyst composition which effected from acids. It was found that, after 5 hours oxidation of naphthene-paraffinic hydrocarbons in the presence of powder RGO the yield of synthesized synthetic petroleum acids rich 15%, the yield of oxysynthetic petroleum acids-21.2 %. The highest yields of synthetic oxy- and petroleum acids (SPA+OSPA) were obtained from powder form of the RGO. The powder RGO showed the highest catalytic activity at initial stages of oxidation of naphthene-paraffinic fractions.
