preparation example Construction

[0080] The preparation method of the aviation gasoline composition of the present invention may also include distilling the alkylation reaction product of C4 olefins and isobutane to obtain a fraction with an initial boiling point of 21-45°C and a final boiling point of 140-153°C as Procedure for blending component A. Preferably, the components obtained have an initial boiling point of 40-45°C. Preferably, the fractions obtained have an end boiling point of 145-153°C. The composition and distillation range of the components obtained by the above method meet the requirements of blending component A described above. The alkylation reaction is carried out in the presence of a catalyst. The catalyst for the alkylation reaction may be an acid, such as one or more selected from sulfonic acid, hydrofluoric acid, and concentrated sulfuric acid. The molar ratio of catalyst to C4 olefin (acid-olefin ratio) can be 1-1.2:1. The temperature of the alkylation reaction can be 4-10°C, the...

The octane number of the aviation gasoline composition is 99.6-103, the vapor pressure and the distillation range meet the requirements, the cost is low, the raw materials are simple and easy to obtain, and the preparation method is simple.

Description

technical field [0001] The invention belongs to the technical field of aviation fuel, and in particular relates to an alkane composition, No. 100 unleaded aviation gasoline composition containing the alkane composition and a production method thereof. Background technique [0002] Aviation gasoline is a high-octane fuel used in aircraft and is an important part of aviation fuel. The octane number is an indicator of the knock resistance of the fuel used in vehicles. Due to the gradual increase in the compression ratio of aviation engines, the requirements for the octane number of the fuel used by the engines continue to increase. In order to ensure that the engine obtains the maximum power under the condition of no knocking and consumes less fuel, it is necessary to add additives that can improve the anti-knocking performance of the fuel into aviation gasoline. Tetraethyl lead is a commonly used antiknock agent that increases the octane rating of the fuel and prevents knock...
