A method for producing high-octane component of motor fuels from olefin mixts. of catalytic cracking by oxidn. of olefin mixt. with nitrous oxide, followed by sepn. of product mixt. as high-octane component, is developed. Other version of the method involves oxidn. of olefin mixt. with nitrous oxide in gas phase at the first stage and at the second stage - condensation of products obtained during the first stage, followed by sepn. of product mixt. as high-octane component. Third version consists in oxidn. of olefin mixt. with nitrous oxide in gas phase at the first stage and at the second stage - condensation of products obtained during the first stage, followed by the third stage involving reaction of mixt. from condensed oxygenates produced at the second stage, or mixt. of carbonyl compds. produced at the first stage, with hydrogen in the presence of hydrogenation catalyst, followed by sepn. of mixt. from hydrogenated products as high-octane component. The proposed method allows to produce ecol. clean high-octane additives with high-octane no.
