Sažetak
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.
