Abstract—In this work were selected the optimal conditions of the dearomatization reaction based on the hydrogenation of benzene to cyclohexane over Rh catalyst, which increases the octane number. The results showed that the study of the catalytic activity of 1% Rh catalysts were active and selective. Carbonized apricot pits 0.5% Rh-promoted exhibits catalytic activity in hydrogenation of benzene in the temperature mode, but by increasing the space velocity rapidly loses activity. Rh catalyst on calcined Al

0C showed markedly less stability in comparison to the other samples. 0.5% Rh- promoted clay-containing zeolite exhibits catalytic activity in the hydrogenation of benzene in the temperature range 280-350
0C, and also has high selectivity to yield of cyclohexane and DMB. As a result, turned improve the environmental performance of motor fuel to achieve the parameters corresponding to Euro-4 standards.
