Abstract

The invention relates to a low-lead aviation gasoline. The low-lead aviation gasoline comprises the following components: A) 50-90wt% of alkylated device oil, B) 3-15wt% of pentane component oil produced by a reformer, C) 0-25wt% of C7 aromatic hydrocarbon component oil produced by an aromatic hydrocarbon extracting device, D) 0-20wt% of isopropylbenzene, and E) 5-15wt% of C6 non-aromatic hydrocarbon raffinate component oil produced by the aromatic hydrocarbon extracting device, wherein the aviation gasoline comprises 0.95-1.2g / kg of lead tetraethyl, less than 0.5wt% of arylamine and less than 10ppm of sulfur; at least one of the component C and the component D is included. The aviation gasoline not only meets a low-lead standard, but also basically does not contain arylamine compounds, so that the environmental pollution of the aviation gasoline is greatly reduced; a good balance between the octane value and the heat value is achieved, the net heat value at least reaches 43.5MJ / kg, and the motor octane value is not less than 99.6.

Description

technical field [0001] The invention belongs to the technical field of fuel application, and in particular relates to a low-lead aviation gasoline and a preparation method thereof. Background technique [0002] Aviation gasoline, also known as aviation piston engine fuel, is mainly used for piston aircraft engines. Aviation piston engines work on the same principle as general automobile engines, but with higher power and lighter weight. Therefore, the quality requirements for aviation gasoline are similar to those for motor gasoline. This aviation piston engine is mainly used in the field of general aviation. [0003] The rapid development of general aviation has made its role in my country's economy and society increasingly prominent, especially after the gradual opening of low altitudes, the demand for general aviation in economic and social development will show explosive growth. The number of general aviation aircraft in China is increasing, and it is expected to appro...
