Description
Technical field
The present invention relates to aviation gasoline technical fields, more particularly, to a kind of No. 91 unleaded aviation gasoline and its producer
Method.
Background technology
Aviation gasoline has several trades mark.One kind being No. 95, and (95/130, i.e., gasoline-air lean mixture is under Cruise Conditions
Motor octane number be 95MON, gasoline-performance number of the air rich mixture when taking off be 130), wherein containing tetraethyl
Lead.It is mainly used for the Large-scale Reciprocating aero-engine for having booster.Another kind is No. 75, and (motor octane number is water white
75MON), unleaded gas.It is mainly used for the small-sized piston formula aero-engine of no booster.It is given birth to by catalytic cracking or catalytic reforming
The high-knock rating gasoline fraction of production increases octane components and a small amount of anti-knock agent and antioxidant is concocted.The capability of antidetonance is high.Boat
Empty gasoline is used as the oil product of piston aviation engine fuel.With sufficiently low crystalline temperature (- 60 DEG C or less) and higher
Calorific value, good vapo(u)rability and enough anti-knock properties.Aviation gasoline is a kind of antiknock gasoline for aircraft, also once
Through being used in racing car.Aviation gasoline is served only on the aircraft of reciprocating engine, and jet plane and turbine-propeller fly
Machine then uses aviation kerosine.
China Aviation gasoline mainly contains the refined component of catalytically cracked gasoline, and adds suitable isopropylbenzene, alkylation
The antioxidant of gasoline, technical octane, isopentane and lead tetraethide and 100,000/several, is additionally added a small amount of corrosion suppression sometimes
Preparation and a small amount of oil-soluble dyes.Gasoline color is different because of dyestuff.Also No. 100, motor octane number 98.6MON, product
Angle value is not less than 130.Also contain lead tetraethide.Different types of aviation gasoline is differentiated for convenience of pilot, aviation gasoline can add
Enter dyestuff.80/87 is red, and 100/130 is green, and 100LL is blue.Aviation kerosine, such as JET A1 are colourless in itself
Or olive drab(O.D), and it is not added with dyestuff.Aviation gasoline volatility is lower than motor petrol, less easily vaporizes.The aviation vapour of today
Gasoline is not distinguished greatly when just being released with generation nineteen fifty and generation nineteen sixty, still pungent to increase by adding highly toxic lead tetraethide
Alkane value, this additive just disappear from motor petrol earlier than the 1980's.
Density of the aviation gasoline at 15 degree Celsius is per U.S. 6.02 pounds of gallon, this is also general aircraft weight and center of gravity
Numerical value used when EQUILIBRIUM CALCULATION FOR PROCESS.At subzero 40 degree Celsius, density is per U.S. 6.40 pounds of gallon.It is Celsius that temperature often rises five
Degree, density will reduce 0. 5 percent.Aviation gasoline is divided into several grades with maximum lead tolerance.Since lead tetraethide is one
The expensive additive of kind, is usually only added in seldom deal to aviation gasoline to reach the octane number of requirement, so aviation gasoline
Lead tolerance usually all than maximum lead tolerance be it is low.In passing, also other kinds of aviation gasoline, especially military class
Type, such as Avgas 115/145.The octane number of aviation gasoline, generally cannot be compared with motor benzine, because of aviation gasoline
Octane number is that the entirely different test engines of Yi Yitai are collated and stipulated with test method.First (numerical value is lower) number
" lean gas gaseous mixture octane number ", and second higher numerical value, be referred to as " rich gas gaseous mixture octane number " (" poor " and " richness ",
Refer to aviation gasoline ratio shared in gaseous mixture).Under opposite, the octane number of motor benzine is usually labeled as
" Ulva Pertusa index " is obtained by being averaged with both " research result " and " automotive engine test value ".
But current unleaded aviation gasoline octane number is low, vapour pressure is high, and boiling range is improper, cannot meet aviation gasoline
It is required that causing yield not high, cost is high instead, and raw material is not readily available, and preparation method is also complex, brings
Big inconvenience.
