Abstract

The invention discloses 91# lead-free aviation gasoline and a production method thereof. The 91# lead-free aviation gasoline is prepared from the following components: industrial isooctane, industrialxylol and industrial isopentane. According to the 91# lead-free aviation gasoline and the production method thereof, the 91# lead-free aviation gasoline is prepared by blending the following components in percentage by volume: 80 to 90 percent of alkane and 10 to 20 percent of aromatic hydrocarbon or is prepared through a blending technology or a petrochemical refining technology; the alkane in the 91# lead-free aviation gasoline provided by the invention takes isoalkane as a main part and has high octane value, low steam pressure and a suitable distillation range; the requirements on the aviation gasoline are met; the octane value of a research method of the aviation gasoline is 97 to 99; the 91# lead-free aviation gasoline and the production method thereof have the advantages of high yield, low cost, simplicity and easiness for obtaining raw materials and simple preparation method.

Description

technical field [0001] The invention relates to the technical field of aviation gasoline, in particular to No. 91 unleaded aviation gasoline and a production method thereof. Background technique [0002] There are several grades of aviation gasoline. One is No. 95 (95 / 130, that is, the gasoline-air-lean mixture has a motor octane value of 95MON under cruising conditions, and the gasoline-air-rich mixture has a grade value of 130 at take-off), which contains tetraethyl lead. It is mainly used for large piston aeroengines with superchargers. The other is No. 75, water white (motor law octane number 75MON), unleaded gasoline. It is mainly used for small piston aeroengines without superchargers. It is blended from high-octane gasoline fraction produced by catalytic cracking or catalytic reforming, high-octane components and a small amount of antiknock agent and antioxidant. High antiknock performance. Aviation gasoline A petroleum product used as fuel for piston aircraft e...
