Abstract
1. Способ получения экологически чистого дизельного топлива путем жидкостной экстракции из гидроочищенной дизельной фракции, отличающийся тем, что дизельную фракцию разделяют методом ректификации на легкий и тяжелый компоненты, подвергают жидкостной экстракции тяжелый компонент дизельной фракции с последующей регенерацией растворителя из рафинатного и экстрактного растворов и компаундированием полученного рафината с легким компонентом дизельной фракции, в качестве растворителя в процессе жидкостной экстракции используют N-метилпирролидон, в качестве легкого компонента используют дизельные фракции с концом кипения до 300°C, а в качестве тяжелого компонента используют дизельные фракции с началом кипения не ниже 260°C. !2. Способ по п.1, отличающийся тем, что массовое соотношение тяжелого компонента дизельной фракции и N-метилпирролидона лежит в пределах от 1:0,5 до 1:2, а температуру в процессе жидкостной экстракции поддерживают на уровне от 40 до 70°C. 1. A method of producing environmentally friendly diesel fuel by liquid extraction from a hydrotreated diesel fraction, characterized in that the diesel fraction is separated by distillation into light and heavy components, the heavy component of the diesel fraction is subjected to liquid extraction, followed by regeneration of the solvent from raffinate and extract solutions and compounding the resulting raffinate with a light component of the diesel fraction, N-methylp is used as a solvent in the liquid extraction process irrolidone, diesel fractions with a boiling end up to 300 ° C are used as a light component, and diesel fractions with a boiling point of at least 260 ° C are used as a heavy component. ! 2. The method according to claim 1, characterized in that the mass ratio of the heavy component of the diesel fraction and N-methylpyrrolidone lies in the range from 1: 0.5 to 1: 2, and the temperature in the process of liquid extraction is maintained at a level of from 40 to 70 ° C.
