Abstract

The invention discloses lead-free aviation piston type engine fuel and a preparation method thereof. The fuel is prepared from a fuel mixture and an additive, the fuel mixture is prepared from the following components in percentage by mass: 10 to 15 percent of isopentane, 18 to 25 percent of low-purity isooctane, 40 to 50 percent of high-purity isooctane, 10 to 15 percent of methylbenzene and 3 to8 percent of xylene, the additive comprises an antistatic agent, an antioxidant and a reinforcing agent, the reinforcing agent is prepared from succinimide, cyclopentane, xylene, ethylene glycol andturpentine, and is prepared by sequentially pumping the components in the formula ratio into a blending tank, uniformly mixing and filtering. According to the present invention, the motor octane number of the aviation fuel is increased, the ASTM D7592 standard is met, the aviation fuel does not contain lead, and the harm on the environment and the human body is low, meanwhile, the preparation method is simple, the overall performance of the aviation fuel oil is improved, the cost is low, and technical support is provided for marketization of domestic high-grade lead-free aviation fuel.

Description

technical field [0001] The invention belongs to the technical field of fuel application and relates to a lead-free aviation engine fuel, in particular to a preparation method of the lead-free aviation piston engine fuel. Background technique [0002] The development of aviation fuel has gone through a long historical process. Every historical change of aviation engine will bring about the rapid development and innovation of aviation fuel. The performance improvement and change of engine will have higher performance requirements for fuel, thus promoting the development of aviation fuel. development of. From the human power source in the engineless flight system, to the aviation diesel power source in the internal combustion engine system, to the aviation piston engine fuel, to the jet fuel power source in the jet engine system, to the high density in the supersonic engine system Hydrocarbon fuels, and then biofuels or solar power sources in new energy engine systems, that is...
