Description
Technical field
The present invention relates to a kind of methanol gasoline, particularly relate to a kind of methanol gasoline that burn into is met not emulsification of water that do not have, belong to the technology of preparing of clean energy.
Background technology
Methyl alcohol is the simplest saturated monohydroxy alcohol of structure, chemical molecular formula CH
3
H.Methanol gasoline is that vehicle fuel substitutes, and is the important component part of new forms of energy.Methanol gasoline is the mixture of methyl alcohol and gasoline.Also comprise the alcohol mixture etc. of methyl alcohol, ethanol, n-propyl alcohol, propyl carbinol and Virahol and the mixture of gasoline.Wherein the methyl alcohol incorporation is generally 5%～30%.Serve as at most to mix 15%, claim the M15 methanol gasoline.Its capability of antidetonance is good, and octane value (RON) increases with the increase of methyl alcohol incorporation, and the toxicity of burning ejecta is littler than common doped fuel, and carbon monoxide content is also less in the exhaust.Combustion cleaning is functional.But general methanol gasoline is to petrolic corrodibility and all bigger to the swelling ratio of elastomeric material, and be easy to layering, methyl alcohol has as the weakness that fuel exists: methyl alcohol is met emulsifying water, thermal value is low, dynamic property is poor, the quantity discharged of the formaldehyde during engine combustion in the discharge rises significantly, can cause very big harm to atmospheric environment and person health and formaldehyde is a kind of stronger carcinogens.
The existing research methanol gasoline data of publishing is a lot, for example: publication number is the application for a patent for invention of CN101892097A, a kind of automobile-used oxygenated gasoline that utilizes crude product methylal and component oil preparation and preparation method thereof is disclosed, component by following weight content is formed: crude product methylal 100-500 part, component oil 500-900 part, anticorrosive swelling agent 0.0005-0.05 part, dewatering agent 0.5-3 part.The embodiment of CN101892097A (3) Zhong Jia place aldehyde accounts for 550 kilograms of 511 kilograms of component oil oil in oil product, embodiment (4) first place aldehyde accounts for 674 kilograms in oil product, 400 kilograms of component oils, and through inventor's inspection by sampling, crude product methylal octane value has only 57, and thermal value has only 5188.Even if add 3 in an embodiment, 93# GB gasoline, octane value is compared with petrochemical industry gasoline with thermal value and is had a long way to go.
Be among the embodiment that provides of some applications for a patent for invention such as CN101768477, CN100580064C, CN101787309A, CN101747954A at publication number: methyl alcohol 70%, gasoline 20%, methyl alcohol 50%, gasoline 38%, methyl alcohol 55%, gasoline 25% etc.
More than invention has been ignored fully, and the increasing octane value of methyl alcohol in oil product thermal value up to standard reduces, and thermal value has only 6000～7000 when the amount of accounting for reaches 50% in oil product, thermal value has only 5500～6500 when methyl alcohol accounts for 70% in oil product when methyl alcohol.So low thermal value, dynamic performance difference has only by enlargement discharge and remedies power, and 1:1.42～1:1.6 has caused the waste of Energy resources greatly.
Summary of the invention
The objective of the invention is to solve the prior art above shortcomings, and a kind of methanol gasoline that does not have the not emulsification of burn into chance water that provides.The present invention has mainly adopted refining methanol, purification, methyl alcohol-formaldehyde reaction, makes problems such as methanol modified, the emulsifying water of burn into chance, the thermal value that has thoroughly solved existing methanol gasoline existence is low, dynamic property difference.Above-mentioned refining methanol, purification, methyl alcohol-formaldehyde reaction are prior art, that is: methyl alcohol-formaldehyde building-up reactions, mainly containing two parts forms, successive reaction still and rectifying tower, methyl alcohol and formaldehyde flow into flow reactor with certain proportion, the discharging one of reactor is gas phase, and another is liquid phase (methylal, water, methyl alcohol).
Methyl alcohol is by above reaction, dehydration, dealcoholysis, passed through certain chemical reaction, decomposed the carcinogenic substance that exists in the corrodibility of methyl alcohol and the methyl alcohol, could really accomplish to be low-carbon (LC), the clean environment energy again in exhaust emissions.
The technical solution that the present invention provides is: this nothing corrosion, meet the methanol gasoline of not emulsification of water, be characterized in that main component has refining methyl alcohol or methyl alcohol-formaldehyde reaction thing or refining methyl alcohol and methyl alcohol-formaldehyde reaction thing, 120# or 200# solvent oil, petroleum naphtha, nonstandard gasoline 60#～70#, solubility promoter, the calorific value rising agent, stablizer, antioxidant and adjustment agent, the weight percentage of its adding is: refining methyl alcohol or methyl alcohol-formaldehyde reaction thing or refining methyl alcohol and methyl alcohol-formaldehyde reaction thing: 10～50%, 120# or 200# solvent oil: 10～20%, petroleum naphtha: 9～15%.
