Problems solved by technology

[0004] Yet the jet fuel that makes in the above prior art, though can be used as jet fuel, also only meets No. 6 jet fuel standard, and No. 6 jet fuel is as high-proportion jet fuel, fails to apply actually because of crude oil source problem, Therefore, it still cannot meet the higher performance requirements of jet fuel for new weapons and equipment

Abstract

The invention relates to coal-based mixed jet fuel and a preparation method thereof. The coal-based mixed jet fuel has a simple preparation process and enlarges the source of the jet fuel. Compared with the single 3# jet fuel, the prepared coal-based mixed jet fuel has more excellent physical and chemical properties, high volumetric specific heat capacity, high volume heat value and higher thermal oxidation stability.

Description

technical field [0001] The present invention relates to a coal-based mixed jet fuel and a preparation method thereof, more specifically to a coal-based mixed jet fuel obtained by mixing a coal-based direct liquefaction fraction with No. 3 jet fuel and a preparation method thereof. Background technique [0002] With the development of aircraft engine technology, petroleum-based jet fuel has been difficult to meet the needs of the new generation of high-speed aircraft. Therefore, it is necessary to develop a new type of jet fuel that matches the existing engine technology. Compared with existing jet fuel, the new jet fuel should be able to effectively meet the requirements of high speed and longer range of aircraft. [0003] my country is a big coal country, but now oil is increasingly dependent on imports, which has an impact on our people's livelihood and national defense. Therefore, it is necessary to develop a new type of high-density jet fuel suitable for aircraft engine...
