Problems solved by technology

The aviation gasoline blending component contains aromatic amines. Although aromatic amines can meet the performance requirements of gasoline antiknock agents, they have more serious wear on metal materials of engine valve seats and other parts, and will make some rubber parts or gaskets shortened life and poor sealing performance
Moreover, the octane number of this aviation gasoline is only 99.6, which is relatively low, which is easy to cause wear and tear on the engine

preparation example Construction

[0075] In some embodiments, the preparation method of the aviation gasoline composition of the present invention further includes the step of obtaining blending component D. The step of obtaining the blending component D may be: gently drying the sweet orange peel in an oven at 40-50°C, such as 46°C, through flowing air for 8-16 hours, such as 12 hours, and drying it at 170-180°C, 7 After extraction into a stable oil-in-water emulsion by steam explosion at -9 bar, the distillation operation is performed for 25-35 minutes, for example, 30 minutes, and the obtained component is blending component D.

[0076] The various parameters of the aviation gasoline composition of the present invention meet the requirements of the ASTM-D7719 standard for No. 102 unleaded aviation gasoline. The motor octane number of the aviation gasoline composition of the invention is not less than 102, which meets the antiknock requirement. The Reid vapor pressure of the aviation gasoline composition of...

Abstract

The invention provides an aviation gasoline composition capable of being used as No. 102 lead-free aviation gasoline and a production method thereof, the aviation gasoline composition contains base oil and an additive, and the base oil contains a blending composition A (mesitylene as a main component), a blending component B (C8 alkylate as a main component), a blending component C (C5-C6 alkane as a main component) and a blending component D (limonene as a main component). The aviation gasoline composition contains the blending component D, can significantly increase the octane number, does not contain tetraethyl lead, methyl tert-butyl ether and aromatic amine compounds, and can reduce environmental pollution. The motor octane number of the aviation gasoline is not less than 102, the octane number is high, the vapor pressure, the distillation range and other indexes meet the requirements of the ASTM-D7719 standard on the 102 # aviation gasoline, the production cost is low, the fuel performance is good, the raw materials are wide and easy to obtain, and the production method is simple.

Description

technical field [0001] The invention belongs to the technical field of fuels, and in particular relates to No. 102 unleaded aviation gasoline and a preparation method thereof. Background technique [0002] Aviation gasoline is a petroleum product used as a fuel for piston aircraft engines, and it is required to have sufficiently low crystallization point and high calorific value, good evaporation and sufficient antiknock performance. Tetraethyl lead is a widely used gasoline additive. Adding tetraethyl lead can significantly increase the octane number of the fuel and improve the efficiency and power of the engine. But at the same time, tetraethyl lead is a highly toxic substance, which will damage the health of the human body and the environment, which is not conducive to the development of green environmental protection. [0003] Most of the aircraft engines currently on the market are old piston engines, which have relatively high octane requirements. High-octane aviation...
