Description
Technical field
A kind of energy-saving environment-friendly methanol petrol engine lubricating oil and preparation method thereof.The invention belongs to the petroleum products additive agent field.
Background technology
Along with China's rapid development of economy, the demand of the energy is day by day increased, especially along with the fast development of automotive industry, we are increasing sharply by automobile pollution, and the demand of the fuel for motor vehicle that causes increases too fast, the exploitation and the consumption that have strengthened petroleum resources.Limited prospective oil and produced quantity are difficult to satisfy the growing demand of society, and constantly the soaring and in the world the contention of petroleum resources is growed in intensity of world petroleum price, make countries in the world all strengthen the research and development of the oil replacement energy, break away from dependence, progressively developed some fuel products additional or alternative gasoline the foreign oil import.
Great deal of experimental proves: no matter be that methyl alcohol or ethanol can be applied to gasoline interpolation substitute field.Alcohols is except that oil, Sweet natural gas, the fuel that oil engine can substitute.Use that Aalcohols fuel is topmost to be also advantageous in that they can both reach the discharging more much lower than hydrocarbon fuel, be of great benefit to reducing topsoil; With traditional engine technology inheritance is arranged, when particularly using gasoline-alcohols propellant combination, engine structure changes little; Their octane value height when making spark ignition engine fuel, can be used for the higher engine of compression ratio in addition, improves the thermo-efficiency of engine, and it is the most promising fuel substitute of oil engine.Promoting the use of ethanol petrol or methanol gasoline in this sense all belongs to feasible concerning oil engine in the use.
The once extensive spread-foodstuff ethanol of China is difficult to as one substituting of share arranged but consider from a long-term for the first period.Because China's national situation is the population of supporting the world 22% with 7% arable land in the world, this is a major premise.By existing state of the art, 3.5 ton-grain food is cooked 1 ton of ethanol, considers the alcoholic acid calorific value, then 5 ton-grain food and 1 ton of gasoline equivalent.The coal that will consume 0.5～0.8 ton in addition is used for fermentation and dehydration.So, 1,000 ten thousand tons of gasoline then need account for 1/10 of China's total output of grain with 5,000 ten thousand tons in grain, so promote ethanol become impossible.Certainly, can consider, or make (present technology does not also have commercialization), but the latter exists large scale collection and transportation problem with stalk and other Mierocrystalline celluloses with other crop producing and ethanols in next life such as cassava and sweet sorghumes.In July, 2007, consider that from environmental protection and national energy present situation State Council promptly halts grain-production alcohol fuel project.
And other sources of alcoholic acid comprise the ethylene hydration method, are subject to the source restriction of ethene; Stalk cellulose system ethanol also only rests on theory stage.And the methyl alcohol source is very abundant, mainly contains following source: coal system methyl alcohol; Sweet natural gas system methyl alcohol; The synthesis ammonia plant combined production of methanol, each all is suitable for scale operation.
Methyl alcohol has following characteristics: the quality low heat value of methyl alcohol has only 45% of gasoline, therefore, under equal thermo-efficiency, the virtual mass specific fuel oil consumption height of Aalcohols fuel.Calculate by mass, contain 50% oxygen in the methyl alcohol, make combustionvelocity fast, and relatively fully; The required air capacity of methyl alcohol perfect combustion is lacked than gasoline, and the also corresponding minimizing of heat that burning back tail gas is taken away is improved the engine overall thermal efficiency; Methyl alcohol theoretical mixture gas quality low heat value is that gasoline theoretical mixture gas quality is low-calorie 94%, so the engine for combusting methanol fuel can obtain the dynamic property roughly suitable with former machine.The latent heat of vaporization of methyl alcohol is 3.6 times of gasoline, and the high latent heat of vaporization and low vapour pressure and lower boiling point will cause gas mixture to form difficulty and engine start difficulty, but can reduce inlet air temperature, improve charging efficiency; Simultaneously,, can improve the inside cooling behind the engine combustion, improve the dynamic property of engine, reduce exhaust temperature because the latent heat of vaporization of methyl alcohol is big.Methyl alcohol has higher octane value, has higher knock resistance, and is very favourable to the thermo-efficiency that recently improves engine by the raising engine compresses, so methyl alcohol is good petrol motor fuel substitute, also is the good additive that improves gasoline octane rating.Regular gasoline and 15%～20% methanol mixed, octane value can reach the level of premium.The boundary of catching fire of methyl alcohol is wideer than gasoline, and engine is worked under rarer gas mixture, and this operating mode scope that will make engine is than broad, and is highly beneficial to exhaust gas purification and reduction oil consumption.The burning-point of methyl alcohol is not easy to the presence of fire accident than gasoline height, than using gasoline safety.Methyl alcohol has swelling action to some non-metallic material (as plastics, rubber etc.), and (as Sn, Pb, Al etc.) have slight corrosive nature to some metallic substance, in use should take appropriate measures.Aalcohols fuel contains hydroxyl, can dissolve each other with water, and the hydrocarbon fuel hydrophobic nature is strong, thereby the intermiscibility of methyl alcohol and gasoline is poor, when methyl alcohol mixes by a certain percentage with gasoline, has demixing phenomenon in certain temperature range.The methanol gasoline normal temperature and pressure is liquid down, processing ease, and the storage band is convenient, but has certain toxicity.
Methyl alcohol mixes according to a certain percentage with gasoline, and after adding certain additive composition propellant combination, low ratio methanol gasoline, as M3, M5, can equally with gasoline use, engine need not done any change, once is used as gasoline sales in a large number on Europe and other places, but generally will add solubility promoter (TBA) etc. in case the fuel layering; Middle ratio methanol gasoline, as M15, M25, engine only need adjust, and technical problem is simpler, once demonstrates in some international fleets of Europe, must add solubility promoter; Gasoline of high proportion methanol as M85, M90, need reequip, optimize engine, and its power, discharging and thermo-efficiency all are better than former petrol motor.
But for methanol gasoline engine, when burning methanol fuel, the external characteristic power of petrol motor descends to some extent, but less to the dynamic property influence of engine.The fuel injection duration of fuel is identical when full load, because the calorific value of methyl alcohol is low, the total heating value of carbinol gasoline fuel decreases when same fuel charge, and the circulation thermal discharge reduces, and causes engine power to descend slightly.But the flame propagation velocity height of methyl alcohol improves the combustionvelocity in the engine cylinder.Because the massfraction of oxygen is 50% in the methyl alcohol, mixture combustion is more abundant relatively, and efficiency of combustion improves, and the specific fuel oil consumption of methanol fuel is reduced, and economy improves.Because methanol gasifying latent heat is big, maximum combustion temperature reduces simultaneously, arranges temperature accordingly and descends to some extent, and the in-cylinder combustion temperature reduces, and can reduce the heat lost by radiation to water coolant of conducting heat and causing, and has also improved the effective thermal efficiency of petrol motor to a certain extent.Engine is when using methanol gasoline, because the vaporization heat of methyl alcohol is higher, gasification is bad during engine starting, more not evaporable methyl alcohol just condenses upon on the cylinder wall and enters in the engine oil, make the engine oil film be washed away and cause oxidation products formic acid that friction wear, methanol gasoline generate and corrosion that formaldehyde etc. causes the endless belt metallic surface in combustion processes.According to the literature, carry out gas chromatographic analysis by the composition of M100 being used oil, the result shows: used and mainly contain water and methyl alcohol in the oil samples, the content of formaldehyde, formic acid is atomic; Formaldehyde, formic acid part that methanol gasoline burning produces are volatilized, but also some and engine oil, additive reaction, cause additive to lose corrosion-resisting function and have accelerated the corrosive wear of piston and cylinder wall.
Therefore in sum, for the methanol gasoline machine, common lubricating oil is no longer suitable, in energy dilemma serious all the more today, promotes for the methyl alcohol class A fuel A, and it is particularly important that the preparation of methanol gasoline engine lubricating oil seems.
