Abstract
Micro-emulsified methanol diesel, energy-saving and emission-reduction belong to Alternative Diesel Fuel.Product of the present invention is made of general goods diesel oil 50%-85%, industrial methanol 5%-85%, emulsifier 30%-70%, cosolvent 10%-30%, fuel assistants 0.1%-2%, combustion catalyst 0.01%-1%, and product is as clear as crystal, and appearance is the same with national standard light diesel.The partial emulsifier non-commercially conventional surfactant that the present invention uses, but synthesized by oneself, product cost is reduced by a relatively large margin.Used emulsifier and cosolvent this product calorific value 9800Cal/g or so, close to ordinary diesel oil calorific value, good dynamic property.
Description
Technical field
The present invention is used to prepare inexpensive micro-emulsified methanol diesel, and energy-saving and emission-reduction belong to diesel oil substitute products, that is, use methanol
Substitute part diesel oil.
Background technique
The diesel engine thermal efficiency is high, and explosive force is big, and horsepower is big, and precise structure is compact, is widely used in haulage vehicle, especially
It is the industries engineering machinery such as high-power large size load-carrying vehicle and ship, agricultural, building, power generation.But application at present goes out three aspects
Problem:
1. supply shortage: the diesel oil and gasoline proportionality of oil plant production are formed by crude oil itself and process flow method restricts, city
On field, gasoline is superfluous, and diesel oil is in short supply.
2. discharge is high: the soot particulate object of diesel emission is 40 ~ 120 times of petrol engine, and smoke particles surface is inhaled
Attached heterocyclic substrate is carcinogenic substance, and country is existing to be strongly required to improve its exhaust emission.
3. non-renewable: petroleum is non-renewable substance, and it is extremely important to study renewable object substitution petroleum.It carries out both at home and abroad
Numerous studies are reached common understanding compared with, and methanol is the convenient substance of diesel oil substitute.
Methanol production raw material: coal, natural gas, biomass such as agriculture, woods waste, even cause lake ecological environment to deteriorate
Fast-growing algae be all renewable resource, alcohols object can be produced.Rich coal resources in China, and methanol production total capacity be greater than disappear
Consumption produces and is greater than pin, particularly suitable to do bavin, gasoline substitute.
The entity and individual of country's research and development methanol diesel-oil are more, achieve fine achievement, but also there is also some problems, return
It receives as follows:
1. storage period is short, standing time was both layered less than one month, and stability is poor.
2. the emulsifier and cosolvent price that use are higher, lead at high cost, deficiency in economic performance.
3. requiring methanol feedstock purity 99.5% or more, product stability is otherwise reduced.Certainty price with high purity, shadow
Ring economic benefit.
4. it is insufficient to burn, generation formaldehyde is not up to standard, causes secondary pollution.
5. methanol and diesel oil arbitrary proportion cannot be made to be mixed generation micro-emulsified methanol diesel.
6. the emulsification system used cannot make the methanol of arbitrary proportion and diesel oil produce micro emulsion methanol diesel-oil.
7. product flash-point problem, after diesel oil mixes methanol, flash-point is down to 14 DEG C or so from 50 DEG C or more, it is difficult to be promoted.
Summary of the invention
One, methanol micro-emulsion diesel main feature of the present invention
1. modified methanol can be miscible with arbitrary proportion with national standard diesel oil or commercial Dissel oil, immiscible material is still as clear as crystal, and appearance is the same as former
It is the same to carry out diesel oil.

Add agent, also known as modified methanol.
3. the preparation of methanol diesel-oil, component and its weight half point ratio are as follows:
Additive 90.4%
0# diesel oil 9.6%
Diesel oil is added in additive to get as clear as crystal M85 methanol diesel-oil is arrived.
It is detected through chemical examination, methanol diesel-oil all technical of the present invention meets light diesel fuel GB252-2000 standard, but flash-point
Exception, because there are methanol in system, declines flash-point.
Certainly, methanol diesel-oil is different from pure diesel oil actually, cannot apply light diesel fuel GB252-2000 standard completely naturally.
