Abstract

The invention belongs to the technical field of aviation fuel, and discloses a low-lead aviation gasoline and a production method thereof. The low-lead aviation gasoline comprises the following components in percentage by volume: 25%-60% of front-fraction alkylate oil, 18%-60% of super fraction alkylate oil, 10%-22% of methylbenzene, 3%-14% of dimethylbenzene, 10%-21% of carbon-5 and less than 0.53ml / l of lead tetraethyl. These components are mixed under a stirring condition; the isopentane content in the obtained low-lead aviation gasoline reaches 0.5%-22%; the content of isooctane reaches 20%-80%; and the motor octane number is greater than 99.5. The front-fraction alkylate oil and the super fraction alkylate oil are obtained by rectifying alkylate oil; the octane number index in the aviation gasoline is effectively improved; components with relatively much colloid are eliminated; carbon formation in a combustion chamber of an aircraft engine is avoided; and the security of the aircraft is improved.

Description

technical field [0001] The invention belongs to the technical field of aviation fuel, in particular to a low-lead aviation gasoline and a production method thereof. Background technique [0002] The so-called aviation gasoline refers to gasoline with specific properties suitable for powering aircraft by being filled into piston engines. The production and use of this gasoline is strictly controlled and supervised, and all indicators must meet national standards. Compared with motor gasoline, the distillation range of aviation gasoline is narrower, and the final boiling point temperature does not exceed 170 degrees; the octane number is also higher, and the motor octane number of commonly used No. 100 aviation gasoline is 99.5 or higher. In addition, there are special requirements for other physicochemical properties. For example, the vapor pressure of aviation gasoline must not exceed 49 kilopascals to avoid air resistance during use; it has strong anti-icing ability, and ...
