Abstract

The invention relates to high-density and high-calorific-value jet fuel. Raw materials of the high-density and high-calorific-value jet fuel include a component in a distillation range at the temperature of 180-300 DEG C in F-T synthesis coal liquefaction and a high-density fuel blending component, wherein the mass ratio of the component in the distillation range at the temperature of 180-300 DEG C in the F-T synthesis coal liquefaction to the high-density fuel blending component is less than or equal to 5:7, the high-density fuel blending component takes inferior heavy oil as a raw material and is subjected to hydrofining, so that cycloparaffin and arene in a distillation range at the temperature of 180-300 DEG C and a tail oil part are obtained, the physical and chemical properties of the high-density fuel blending component accord with standards of RP-3 jet fuel, the density of the high-density fuel blending component is 960-980kg / m<3>, and the net calorific value is 43.8-44.8MJ / kg. By virtue of the design, the density and calorific value of the jet fuel are improved, and production cost is low.

Description

technical field [0001] The invention belongs to the field of aviation fuel, and in particular relates to a jet fuel with high density and high calorific value, which is made from components with a distillation range of 180-300°C in F-T synthetic coal-to-oil, and is suitable for increasing the density and calorific value of jet fuel. reduce manufacturing cost. Background technique [0002] Coal-to-liquids is a technology that uses coal as raw material to produce oil products and petrochemical products through chemical processing, which includes two technical routes of direct coal liquefaction and brief liquefaction. Among them, the indirect liquefaction of coal is to gasify coal first, and then convert it into hydrocarbon fuel through Fischer-Tropsch (F-T) synthesis. The F-T synthesis process is the process of preparing hydrocarbons from synthesis gas. Syngas can be prepared from raw materials such as natural gas, coal, light hydrocarbons, heavy oil, and biomass. According...
