METHOD FOR PRODUCING COMPONENTS FOR ENGINE FUELS

摘要

1. A method for producing components for engine fuels, comprising reforming in the presence of platinum-containing catalyst with a subsequent separation of liquid high-octane products from gaseous products (hydrogen and C1-C4 hydrocarbon gases) and recycling C1-C4 hydrocarbon gases into the reforming area, characterized in that the gaseous products of reforming are subjected to separating by binding hydrocarbon at contacting with aromatic hydrocarbons in the area of catalytic hydrogenation, after which the products of hydrogenation are separated and C1-C4 hydrocarbon gases are recycled into the reforming area. 2. The method according to claim 1, characterized in that C1-C4 hydrocarbon gases are continuously recycled in a closed area from the hydrogenation area to the reforming area and back, keeping them in the process. 3. The method according to claim 2, characterized in that an additional amount of C1-C4 hydrocarbon gases is supplied into the recycling gas flow from an outer source. 4. The method according to claim 1, characterized in that speed of hydrogen binding in the hydrogenation is maintained being equal to the speed of hydrogen separation in the reforming area. 5. The method according to claim 1, characterized in that the process in the hydrogenation is performed at a pressure being not less than 0.3 MPa and at a temperature 50-300 degree C using a catalyst comprising VIII group metal(s). 6. The method according to claim 1, characterized in that the hydrogenation products are separated to cyclohexane-type hydrocarbons and C1-C4 hydrocarbon gases by a method of medium-temperature phase separating. 7. The method according to claim 1, characterized in that the bound hydrogen is removed from the process in the form of the cyclohexane-type hydrocarbons. 8. The method according to claim 1, characterized in that the cyclohexane-type hydrocarbons are directed into the area of catalytic dehydrogenation with a subsequent separation of the dehydrogenation products to aromatic hydrocarbons, which are recycled into the hydrogenation area, and hydrogen. 9. The method according to claim 8, characterized in that the process in the hydrogenation is performed at a temperature 300-500 degree C using a catalyst comprising VIII group metal(s). 10. The method according to claim 1, characterized in that C1-C4 hydrocarbon dissolved in liquid products are separated and then recycled into reforming area for mixing liquid raw material. 11. The method according to claim 1, characterized in that C1-C4 hydrocarbon dissolved in the cyclohexane-type hydrocarbons products are separated and then recycled into reforming area for mixing liquid raw material. 12. The method according to claim 1, characterized in that the reforming area comprises one reactor or a system of several reactors.
