METHOD OF INCREASING STABILITY OF OXYGEN-CONTAINING COMPONENTS OF MOTOR FUEL AND CONTROLLING OXYGEN CONTENT THEREIN Russian patent published in 2017 - IPC C10G69/04 C10L1/00 C07C45/00 C07C5/02 

FIELD: fuel.

SUBSTANCE: invention describes a method of controlling content of oxygen in high-octane component of motor fuel based on carbonyl compounds of general formula, where R¹ is H, or alkoxide -O-C_nH_2n+1, or a hydrocarbon radical of general formula -C_nH_2n+1; R² is a hydrocarbon radical of general formula -C_nH_2n+1; n is a number from 1 to 5 or mixture thereof, and controlling chemical stability of this component consists in that, carbonyl compounds of said general formula or mixture thereof in gaseous phase in excess hydrogen are passed over a layer of composite material, consisting of a mechanical mixture of a hydrogenation catalyst and a dehydration catalyst, at temperature of 100–400 °C and pressure of 1–100 atm.

EFFECT: technical result consists in increasing activity, selectivity and stability of operation of catalysts for hydrogenation of branched ketones to corresponding branched alkanes, and/or alcohols and/or their mixtures.
