Manioca biofuel mixture
Affiliated field
The present invention relates to use for diesel engine fuel, particularly a kind of manioca biofuel mixture.
Background technology
The main fuel that existing diesel uses is a petroleum diesel, because it is by getting in the oil, oil belongs to Nonrenewable resources, increase along with diesel engine quantity, petroleum resources are in continuous minimizing, and the release of diesel combustion product causes topsoil, and the annual new car output in the world is about 5,000 ten thousand at present, whole world automobile pollution about 7.5 hundred million (containing motorcycle).Along with rapid development of automobile industry, the consumption of gasoline and diesel oil increases with the increase of automobile pollution, has also brought problems such as automobile exhaust pollution simultaneously.Over nearly 20 years, though improving the oil product combustion processes, aspects such as tail gas clean-up have all obtained remarkable progress, but still can not meet the demands, the factor excitation people of this two aspect research and develop new fuel substitute, at present, the U.S., Canada, Britain, Japan, Brazil, states such as New Zealand have all carried out the research work of vegetables oil as alternative fuel for diesel engine, and obtained certain achievement, Japanese government's approved biofuel is provided by the service station as merchantable fuels, but, generally speaking, vegetables oil directly has following difficulty as diesel oil: (1) plant oil viscosity is big, and the kinematic viscosity ratio diesel oil of general vegetables oil is high 10 times, and this will cause fuel oil difficulty of transportation in diesel engine, atomization badness during through nozzle, incomplete combustion, easy carbon distribution when burning in existing diesel makes the piston bonding, filter element blocks, can not life-time service; (2) the plant oil flash is than diesel oil height, and volatility is poor, is unfavorable for the formation of gas mixture in the diesel engine cylinder, the difficult phenomenon of catching fire can occur; (3) the cloud point height of vegetables oil causes the cold start-up difficulty; (4) vegetables oil of unburn and incomplete combustion contacts with lubricating oil along cylinder wall, makes lubricating oil contaminated and rotten, causes component friction aggravation, and this just need do bigger improvement to the existing diesel engine, obtain comparatively difficulty of general popularization.
Since nineteen thirties; biofuel has been considered to the substitute of petroleum base diesel oil; attempted in some cases vegetables oil is added in the petroleum diesel; by vegetables oil is carried out chemical process; can relax problems such as the energy dilemma of petroleum diesel and environmental pollution; also can solve simultaneously many difficulties that above-mentioned vegetables oil is done diesel-fuel; the subject matter of biofuel is the cost height at present; vegetables oil such as soybean oil; rapeseed oil; plam oil and sunflower seed oil are edible oil; edible oil is widely used in diesel-fuel; lack realistic meaning; and plant these plants and generally need take big area and plough, the area that comparatively lacks for the soil, arable land is unfavorable for promoting.Therefore according to statistics, 75% of biodiesel manufacture cost is a raw materials cost, is the key that can biofuel practicability thereby adopt cheap raw material and improve that transforming reduces cost.
Chinese patent 88102687 discloses a kind of novel fuel for diesel engine, it is to be used for diesel engine as diesel-fuel or with fuel that the diesel oil of different model mixes as diesel engine separately with vegetable oil Chinese catalpa oil, but when Chinese catalpa oil mixes with the diesel oil of different model, use the desired temperature difference bigger, between-12 ℃~25 ℃, and for the runtime of diesel engine qualification being arranged also, these all make this novel fuel for diesel engine use significant limitation.
At present, the floorboard with high oil content of manioca fruit is about 60%, surpasses the common oil crops of China such as rape and soybean.It is reported that every mu of ground on average can produce 650 kilograms in manioca dry fruit, can extract and process about 180 kilograms of curcas oils.The scientific research personnel will utilize bio-technology improvement manioca kind, improve the oleaginousness of fruit.For this reason, the expert has set about the different certainly manioca resource of collecting all over the world, makes up the gene pool of this plant.Because manioca is strong to adaptive capacity to environment, the expert thinks that it can be used for the afforestation of arid area.
Summary of the invention
Purpose of the present invention promptly is to overcome the shortcoming of prior art, provide a kind of preparation cost cheap, do not change the manioca biofuel mixture of the engine of existing petroleum diesel use, the manioca raw material that its adopts can be planted widely, need not occupy cultivated land the output height.
Purpose of the present invention is achieved through the following technical solutions: a kind of manioca biofuel mixture, mixture contains following components in weight percentage: curcas oil 5~30%, diesel oil 60~94%, methyl alcohol or ethanol 1~10%.With curcas oil 20%, diesel oil 77%, methyl alcohol or ethanol 3% is good.Above-mentioned diesel oil is 0 #Diesel oil, 10 #Diesel oil, 20 #Diesel oil, 5 #Heavy gas oil, 10 #Heavy gas oil or 20 #Heavy gas oil.Need to add tensio-active agent in curcas oil, diesel oil, methyl alcohol or the alcohol mixture, the weight ratio of curcas oil, diesel oil, methyl alcohol or alcohol mixture and tensio-active agent is 0.5~50:1000, tensio-active agent is made up of oleic acid, ethyl lactate, diglycollic amide, isooctyl ester nitrate, and their weight percent is oleic acid 25%, ethyl lactate 15%, diglycollic amide 5%, isooctyl ester nitrate 55%.
By top narration as can be seen, the present invention has the following advantages:
(1) has good environmental protection characteristic.Substitute the part mineral diesel, mainly show owing to sulphur content in the manioca biofuel mixture is low, make that the discharging of sulfurous gas and sulfide is low, curcas oil contains oxygen in 10%, the quantity of the pollutents such as suspended particles, volatile organic compounds, polyaromatic hydrocarbon and carbonic acid gas that produce when burning is simultaneously also lacked than mineral diesel, in the stdn test, the curcas oil biological degradation is little organic molecule, carbonic acid gas and water.
(2) has good low-temperature engine starting performance.
(3) has lubricity preferably.Make the wear rate of oil injection pump, engine cylinder-body and connecting rod low, long service life.
