Description
Technical field
The invention belongs to fuel applications technical field, it is related to a kind of unleaded aviation gasoline and preparation method thereof.
Background technology
With the flourishing of national economy, low latitude field is opened gradually, and General Aviation cause shows extensively in China
Wealthy development prospect.Demand of the market to high grade aviation gasoline is still being continuously increased, and needs the aviation for developing the higher trade mark
Gasoline.
Currently, the state of development of China's high grade aviation gasoline is, the trade mark is low, unstable quality, to engine flexibility
The popularization difficulty of difference, the unleaded aviation gasoline of high grade is larger.Domestic high grade aviation gasoline demand is with leaded 91# and 100#
Main, the overwhelming majority is produced by petrochina Lanzhou Petrochemical Company.
Aviation piston type engine requires to use high-octane aviation gasoline.Nineteen twenty-one, General Motors Corporation are sent out for the first time
Existing, lead tetraethide, which is added in gasoline, can reduce pinking, improve octane number.Aviation gasoline manufacturer is mostly by boat at present
Lead tetraethide is added in empty gasoline to improve fuel economy, increases the Ulva Pertusa ability of gasoline.
Lead tetraethide itself is extremely toxic substance, it can by the number of ways such as respiratory system, digestive system and skin into
Enter human body, cause photis, phonism, stupor or even death will be made one when serious.The lead oxide that generates is also after lead tetraethide burning
Extremely toxic substance causes providing brain with oxygen insufficient, causes Poisoning by severe jamming human metabolism's activity after it invades brain
Neuropathy.Numerous studies show that the usage amount of blood lead content and doped fuel is closely related in metropolitan resident's body.In view of
The adverse environment of lead tetraethide influences and its harm to human health, the developed countries such as America and Europe the mid-90 in last century
It completely forbids motor petrol and uses lead tetraethide.On January 1st, 2000, the publication of China national Administration of Quality and Technology Supervision are " automobile-used unleaded
Gasoline mandatory national standards ", and start to be forbidden to use leaded motor petrol in the whole nation.
However, in aviation gasoline application field, due to not yet finding ripe lead tetraethide substitute at present, also permit
Perhaps lead tetraethide is added in aviation gasoline.Nevertheless, the developed countries such as America and Europe to lead tetraethide adding in aviation gasoline
Dosage has carried out stringent limitation, and the trend of reduction year by year is presented.Recently it has been reported that, the leaded chemical combination in aviation gasoline
Object has caused the flight range pollution at water source nearby and obviously increasing for toxic neuropathy number of the infected.
Since the pressure of environmental and human health impacts is increasing, the research and development of unleaded aviation gasoline are more and more weighed
Depending on.The rapid development of unleaded aviation gasoline will be to solve the problems, such as that General Aviation lead contamination indicates a practicable road.Cause
This, provides the unleaded aviation gasoline that a kind of physical and chemical index can meet domestic and international unleaded aviation gasoline standard, just becomes the skill
Art field urgent need to solve the problem.
The fuel of nitrogenate can form nitrogen oxides NO in burningx.Nitrogen oxides is cause atmosphere pollution main
One of pollution sources.The increase of nitrogen oxide emission makes China's Acid Rain Pollution from sulfuric acid type to compound turn of sulfuric acid and nitric acid
Become, the rapid growth of discharged nitrous oxides exacerbates the degradating trend of region acid rain.
The NO that gasoline combustion generatesxAnd NH3And its effect product can be floated into troposphere, therefore coverage bigger；
NOxNon-linear photochemical effect can also generate a large amount of Tropospheric ozone.The sedimentation of N includes gaseous state and solid-state, passes through air
Balancing Analysis of Charges and model value calculate, and can calculate the settling amount of a certain specific particle, the active nitrogen of part sedimentation
Compound can be again with NH3, NO or other NOxForm discharge into the atmosphere.
The multinomial patent application publication of Dutch Shell companies, such as CN104593094A to CN104593098A and
CN104593101A and CN104593102A discloses high-octane lead-free aviation gasoline, however these unleaded aviation gasoline need
To include the aniline of up to 2-10 volumes %.Since novel arylamine compound burning will produce oxynitrides, air is produced
Raw oxynitrides pollution.
Main technical indicator is as shown in table 1 below in American-European existing unleaded aviation gasoline standard ASTM D7547-14.
