Description
Technical field
The present invention relates to liquid fuel field, more particularly to a kind of alcohol-oil fuel and preparation method thereof.
Background technology
Currently, in domestic Vehicular methanol petrol and ethanol petrol allocating technology, to make methanol, ethanol and gasoline, dissolving each other,
Need to add cosolvent wherein to improve its stability, the addition of various cosolvents, methanol fuel can be greatly lowered
Phase separation temperature, substantially alleviate the production of methanol fuel, the intermiscibility contradiction in.But the cosolvent developed is most
It is made up of the different organic matters such as polyalcohol, aromatic hydrocarbons, esters and ethers, there is following point:Less stable, it is unfavorable for first
Alcohol gasoline is stored for a long time, lamination easily occurs compared with cryogenic region in the winter time;Versatility is not strong, and most cosolvents aim at a certain model
Methanol gasoline configures, and it is most for methanol content it is relatively low or higher in the case of;Water resistant phase separation performance is poor, Xuzhou Yong Sheng Energy Section
Skill Co., Ltd methanol vapor additive only has M15 report, and economic benefit is not high, is added into M40 methanol gasolines equal
Under experimental condition, meet the placement of water 0.5% and turbid phenomenon occur in 10 days, put in -35 DEG C of low temperatures and occur within 6 hours to be separated now
As being restricted the popularization and application of methanol gasoline.
Improve at present in the research of methanol gasoline resisting phase separation performance and many deficiencies also be present:1st, only managed from resisting phase separation
Proposed a plan by angle, can not consider in additive addition vehicle fuel adapt to engine, vehicle needs and tail gas
The environment of discharge influences, and additive part material is unfavorable for the dirty development trend of vehicle fuel emission reduction drop;2nd, the preparation of additive
Complex process, it is less economical;3rd, the part material of additive is unprocessed using residue raffinate, and toxic and exhaust emissions is exceeded
Risk.
The content of the invention
For the problem present on, the invention provides a kind of alcohol-oil fuel, not only solves alcohol-oil fuel phase separation
The problem of, and the energy discharged during burning is suitable with gasoline, i.e., and one liter of fuel is equal to one liter of pure gasoline and used.Discharge pollutants
It is greatly reduced, charcoal discharge capacity significantly reduces.
Technical scheme is as follows:
A kind of alcohol-oil fuel, including the raw material of following volume fraction are made:
Low-carbon alcohols 20-40%;
Gasoline 60-80%;
Nitromethane 0.8-2.0%;
Cosolvent 0.3-1%;
The cosolvent is prepared from the following raw materials in parts by weight:Lubricating oil 90-00 parts, antioxidant 0.5-2 parts, group of the lanthanides
Rare earth metal 0.5-2 parts, the lubricating oil are IC engine lubricating oil oily based on mineral oil, preferably gasoline engine SF levels machine
Oil, diesel engine CD level machine oil;The antioxidant is BHT, Diphenylamine Antioxidant or 3,7- diisooctyl phenthazine;The lanthanum
It is that rare earth metal is lanthanum, praseodymium or erbium.
The preparation method of the cosolvent is as follows:All raw materials are heated to 85-200 DEG C, insulation 24- under anaerobic
48h, is cooled to room temperature, and the liquid particle of concentration, separation, removing more than 5 microns produces the cosolvent.
The low-carbon alcohols are methanol or ethanol;
The alcohol-oil fuel, is made using following methods:
(1) cosolvent is reconciled and stirred in proportion with nitromethane;
(2) gasoline is added into said mixture and is stirred, is stood after miscible;
(3) low-carbon alcohols are added into said mixture, stirring is miscible, stands and produces.
Step (2) stands 1 hour;At least 24 hours are stood in step (3).
The beneficial effects of the invention are as follows:The alcohol-oil fuel of the present invention, prepare simply, the addition of nitromethane improves fuel
Burning velocity, reduce the discharge of NOx in tail gas, exhaust emissions is far superior to state V, and the addition of cosolvent solves alcohol content and existed
20-40% problem of phase separation, still there is preferable stability under cryogenic, also improve the energy of alcohol oil, higher than existing
The low heating value of some alcohol-oil fuels, the energy of the alcohol-oil fuel is suitable with gasoline, and its another very important effect is exactly
The firing property of nitromethane is reduced, in the amount ranges of the present invention, explosion danger will not occur.It is single if being added without cosolvent
Detonation can occur for the pure combination for adding nitromethane and other cosolvents.
