| titleOfInvention | Method for producing aircraft fuel |
| abstract | FIELD: fuels. n SUBSTANCE: invention relates to a method for producing aircraft fuel by contacting a mixture of gas oils of secondary origin containing at least 60 wt.% aromatic hydrocarbons with a hydrogen-containing gas at elevated temperature and pressure in the presence of a catalyst loaded into a system of reactors with separate reaction areas, followed by rectification of the hydrogenate. A package of catalysts sulfided immediately before the process in the system of reactors is used as a catalyst, consisting of 85 to 90 vol.% of the main layer and 15 to 10 vol.% of the protective layer located above said layer. The main layer consists of two hydroprocessing catalysts. An alumina-nickel-molybdenum catalyst with a total content of active metal oxides per calcined catalyst from 22 to 34.5wt.% and phosphorus oxide from 1.6 to 2.8 wt.% is placed first in the direction of movement of the gas-feed mixture in the amount of 75 to 85 vol.% of the main layer. An alumina-nickel-molybdenum catalyst with a content of active metal oxides per calcined catalyst from 45 to 63 wt.% and no more than 10 wt.% silicon oxide is placed second in the direction of movement of the gas-feed mixture in the amount of 25 to 15 vol.% of the main layer. The protective layer constitutes a composite located in the direction of movement of the gas-feed mixture and consisting of 20 to 25 vol.% of a highly porous cellular active filtration material with an open porosity of at least 50% and a cellularity of 10 to 30 mesh, 20 to 25 vol.% of an aluminium-nickel-molybdenum diolefin hydrogenation catalyst based on a highly porous cellular material with a cellularity of 10 to 30 mesh, open porosity of at least 50% and a total content of active metal oxides per calcined catalyst of at least 2.5 wt.%, 40 to 45 vol.% of an aluminium-nickel-cobalt-molybdenum catalyst with a total content of active metal oxides per calcined catalyst no less than 6 wt.% and a content of silicon oxide no more than 15 wt.%, 10 to 15 vol.% of an aluminium-nickel-molybdenum catalyst with a total content of active metal oxides per calcined catalyst of 25 to 30 wt.% The method is executed at a pressure of 16 to 30 MPa, a temperature of 340 to 420°C, a volumetric feed supply rate of 0.3 to 1.0 h -1 , a hydrogen-containing gas/feed ratio of 1500 to 3000 nm 3 /m 3 . 20 to 30 vol.% of the hydrogen-containing gas therein is supplied for mixing with the feed, and the rest of the hydrogen-containing gas is evenly distributed between the third and the twentieth reaction areas of the reactors. The target fraction isolated from the hydrogenated product, boiling within the temperature range of 195 to 280°C, can be used as aircraft fuel after introduction of an anti-wear and/or antioxidant additive. n EFFECT: technical result of the invention is expansion of the lower limit of the pressure value and implementation of the process at a pressure of 16 to 30 MPa, wherein the operational life of the main catalyst is doubled and the yield of the target product is increased by up to 10 wt.% from the source material of the process. n 2 cl, 1 tbl |
