“…Decrease in the proportion of aromatic hydrocarbons in oils and petroleum products can be achieved by various methods, one of the main catalytic processes is hydrodearomatization of gasoline fractions in the presence of highly efficient catalysts, in which process the operational characteristics of petroleum fuels, oils and raw materials for petrochemical refining are improved. [2][3] Scientists from many countries are engaged in the problem of hydrodearomatization of oil products -USA, Great Britain, France, Germany, Japan, Russia, China, Poland etc. [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] The main development trends in the field of hydrodearomatization of automotive fuels and the development of catalysts based on platinum metals are aimed to reducing the cost of catalysts (decrease of the content of noble metal, selection of carriers and modifiers) and increasing their stability and resistance to sulfur compounds.…”

The work is devoted to the catalytic hydrodearomatization of gasoline fractions to reduce the content of benzene and polycyclic aromatic hydrocarbons and the catalytic oxidation of carbon monoxide in motor vehicle exhaust gases. At hydrodearomatization of gasoline fractions of LLP "Atyrau Refinery" on 0.2% Rh-Pt/Al 2 O 3 bimetallic catalyst, the benzene content of the stable catalysate LG fraction decreased from 3.23 to 0-0.03% and the content of aromatic hydrocarbons decreased from 55.04 to 28.40% and benzene was completely removed of the fraction Straight-run gasoline AVT with the decrease of aromatic hydrocarbons from 9.93 to 5.04%. CO oxidation with 100% conversion over metal block Pt-Co/Al 2 O 3 catalysts begins already at 100°C, the optimal volume rate for the oxidative conversion of CO is 80000-100000 h -1 . Tests on a pilot plant showed complete removal of monoxide from the exhaust gases of internal combustion engine.

Liquid-phase hydrogenation of benzene ring in gasoline fractions of Atyrau Oil Refinery LLP (Kazakhstan) was studied. Mono-and bimetallic catalysts on the basis of platinum metals on various carriers were synthesized. It was succeeded to reduce aromatic compounds content (totally) for "hydrogenate" fraction to 0.6-4.64 % (in initial gasoline -11.2 %), and also to completely exclude the content of benzene from final sample or to reduce its quantity to 0.06 % (in the initial sample -2.54 %). For the fraction "stable catalysate" benzene content was reduced to 0.15 wt. % (in the initial sample -5.17 % wt.), benzene conversion -97 %. For the fraction "hydrogenate" aromatic compounds content was decreased from 13.70 to 2.26 wt.%. For the "stable catalysate" an amount of aromatic compounds was reduced from 51.5 to 22.96 wt.%. At catalytic hydrodearomatization of the gasoline fractions octane number was not reduced.
