Description
Technical field
The present invention relates to fuel areas, are related specifically to automobile-used cleaning composite power alcohol of one kind and preparation method thereof.
Background technique
Dependence of the world today to the energy has arrived inseparable degree especially to the dependence of vehicle used energy, and has
The reserves and yield of limit, it is difficult to meet the needs of people are growing, oil price grows to even greater heights, and people can't bear the heavy load, more
For the serious is, at any time there is the danger of oil starvation oil-break, threaten the economic security of country, how to utilize existing resource, into
Row effectively integrates, and to supplement or even substitute existing petrochemical industry gasoline, reduces the single dependence to petroleum, it has also become the hot spot of research is asked
Topic.Methanol is one of the alternate resources for most playing future, is had good burning performance, and more environmentally friendly.By methanol and coal inhibition and generation
Methanol gasoline can be obtained by proper proportion mixing in work extract (such as methanol, pumice brain), and be also known as used as power alcohol at home, first
Alcohol fuel compares that combustion heat value is higher, pernicious gas content is lower in exhaust emissions amount with existing petrochemical industry gasoline, can be not
It directly uses, can also be arbitrarily used in mixed way with existing petrochemical industry gasoline in the case where changing existing automobile engine system structure,
It adds more convenient.
But it is existing using methanol as raw material be made power alcohol there are the shortcomings that it is also very prominent: methanol have corrosion swelling
Property, many components are all made of rubber, metal in fuel cut engine system, and rubber product can occur molten in methyl alcohol
Swollen, phenomena such as being hardened, become fragile or softening, metal can also be corroded in methyl alcohol, therefore methanol is added and excessively easily causes oil pipe
Oil leak；In addition, methanol with it is poor as other components intersolubility in composite power alcohol made of raw material using methanol, engine will be reduced
Operation stability.
In conclusion it is existing using methanol as have the defects that in composite power alcohol made of raw material two it is quite fatal:

Specific embodiment
Embodiment is given below so that the present invention to be specifically described, it is necessary to which indicated herein is following embodiment
It is used to further illustrate the present invention, should not be understood as limiting the scope of the invention, the ordinary skill in the field
Personnel still fall within protection scope of the present invention to some nonessential improvement of the invention made or adjustment according to this embodiment.
The preparation of composite power alcohol in embodiment 1-6 and comparative example 1-2
It is formulated by table 1, methanol, light naphthar, re-request or light aromatic hydrocarbons, acetone is mixed, then sequentially add n-butanol, lubrication
Agent and benzoic acid, stirring 10-20min to obtain the final product.
Wherein, the lubricant is fatty alcohol.
The calorific value and octane number of composite power alcohol can be improved in the above component, re-request or light aromatic hydrocarbons, and fatty alcohol can increase machine
Tool lubrication, pumice brain can be changed methanol physicochemical property, improve its startability, frost resistance and warm-up property；Benzoic acid can reduce corrosion
Property and swellability；N-butanol may make methanol preferably to merge with other components, and enhance the water-resistance of composite power alcohol.
The content unit of each component is parts by weight in the following table 1.
Test one
8 carefully Chinese mugwort bodyguard board CAP7160BAC3 type cars are filled it up with the composite power alcohol in embodiment 1-6 and comparative example 1-2 respectively
Fuel tank, upper drive test examination (oil consumption: real is carried out in the environment of temperature is 14 DEG C, atmospheric pressure 100kPa, relative humidity are 37%
Apply the distance of every 50L composite power alcohol traveling 800-840km in a 1-6, every 50L composite power alcohol traveling in comparative example 1-2
760km-790km)；In addition, " spark ignition type starts the content of pernicious gas using GB 18285-2005 in the tail gas discharged to it
Machine automobile exhaust pollutant discharge limit value and measurement method (Double idle state method and simple condition method) " and HJ/T240-2005 HJ/T
240-2005 " principle and method for determining spark-ignition engine vehicle in use simple condition method tailpipe emission limit value " into
Row test, test result see the table below shown in 2.
Test two
The oil pipe O-ring that radius is 2.5cm is separately immersed in the composite power alcohol in embodiment 1-6 and comparative example 1-2,
The radius size for measuring the O-ring afterwards for 24 hours, as a result see the table below shown in 2.
Test three
Test material: red copper: meet 5096 copper corrosion requirement of GB/T；Brass: meet H70 copper requirement in GB/T 5231.
Red copper test piece, brass test piece are soaked in respectively in the composite power alcohol in embodiment 1--6 and comparative example 1-2,2
After a month, test piece observation, weighing are taken out, and unit of account area quality changing value, test result see the table below shown in 2.
As shown in Table 2, after the composite power alcohol burning in embodiment 1-6 in the tail gas that discharges pernicious gas content compared with
It is low, and O-ring does not swell after the composite power alcohol impregnates for 24 hours, red copper test piece, brass test piece are in the composite power alcohol
Mass area ratio changing value is also smaller.Result above proves that the automobile-used cleaning composite power alcohol in the present invention can effectively mitigate
The corrosion swellability of methanol, and the content of pernicious gas is far below the limit value in table 2 in tail gas.
The benzoic acid content of comparative example 1 is relatively low, although the content of pernicious gas is low in tail gas, two discovery of test is for 24 hours
The radius of later O-ring is swollen by 2.5cm as 3cm, the mass area ratio variation of metal testing plate after three discovery of test 2 months
It is worth higher；The benzoic acid content of comparative example 2 is higher, harmful in tail gas although the test result of test two, test three is more excellent
The content of gas is significantly raised.When i.e. methanol additional amount is relatively low, methanol can not be mitigated to the swelling action of rubber and to gold
The corrosiveness of category；When methanol additional amount is higher, then it be easy to cause burning insufficient to improve polluted gas content in tail gas,
It can be more than even GB 18285-2005 " spark-ignition engine automobile exhaust pollutant discharge limit value and measurement method when excessively high
(Double idle state method and simple condition method) " in limit value.
In conclusion the additional amount of benzoic acid preferably must be held in particular range in methanol formula system of the invention,
Not only the content of pernicious gas in tail gas could be controlled in lower range, but can mitigate methanol to the swelling action of rubber with
And corrosion of metal is acted on.
