Abstract
The invention discloses to provide a vehicle clean environmental-protection methanol gasoline, composed of basic oil and additive. Firstly, refine the basic oil by zeolite screen to eliminate water, colloid and harmful metallic ion. It compounds additive with toluene, mixed benzene, methylcyclopentadiene three carbon manganese, trimethyl phosphate, sodium hydroxide, oligomer and corrosion resisting agent to make additive mixed solution, and then proportionally adds the mixed solution in the basic oil for blending to prepare the product. It has advantages of good antiknock quality and stability, obvious energy conserving effect, fine accelerating performance, obvious reduction of tail gas discharge, non-causticity, etc.
Description
The invention belongs to automobile-used fuel substitute, particularly be refining, the prescription and the additive of methanol gasoline, methanol gasoline base oil.
At present, the fuel that explosive motor uses is petroleum products substantially, as gasoline, diesel oil and kerosene etc.Along with the minimizing day by day of petroleum resources, national governments constantly encourage and seek the alternative fuel of explosive motor; On the other hand, flourish along with transportation, a large amount of uses of automobile fuel gasoline, discharge tail gas has caused severe contamination to atmospheric environment, and existent environment of people in serious threat.Therefore, large quantities of vehicle fuels that substitute arise at the historic moment, with situation that solves undue dependence oil and the environmental protection problem of more and more paying attention to.Wherein use at most, development is methanol gasoline faster, is to be spiked in the motor spirit to replace commercial labeled gasoline as gasoline-like alternative with part methyl alcohol.Because the synthetic route of methyl alcohol is (coal, Sweet natural gas, naphtha, heavy oil etc. and the synthetic route of depositing) extensively, and the burning back is little to the pollution of environment, be subjected to the common concern of automobile industry at present, so the researchdevelopment clean environmental-protection methanol gasoline is the ideal fuel substitute again.
Ubiquity that anti-knocking property are poor in the present methanol gasoline, poor stability, energy-saving effect is poor, acceleration characteristics is poor, have corrodibility, exhaust emissions exceeds standard, can not be mixed with other oil product, uses a series of problems such as also there being the low-temperature cool starting weak effect for extremely frigid zones.Mostly the problems referred to above are to adopt per-cent, the interpolation certain quantity of additive of adjusting each component in the production of methanol gasoline, discrete also will improve motor car engine a little at the characteristics of methanol gasoline.Though these ways can solve some problems, the moisture content that in base oils such as used gasoline, methyl alcohol, contains, colloid, deleterious heavy metal ion and some problems can not or not solved.
The purpose of this invention is to provide a kind of vehicle clean environmental-protection methanol gasoline; these oil product anti-knocking property, good stability; energy-saving effect is obvious; acceleration characteristics is good, and exhaust emissions obviously reduces, do not have corrodibility, can cleaner engines; can be mixed with other oil product; cheap, have the good low-temperature cold starting effect, adapt to northeast extremely frigid zones large-scale production and use especially.
The concrete technical scheme of the present invention is: vehicle clean environmental-protection methanol gasoline is made up of base oil and additive, and the synergy that can play behind base oil and the compound compatibility of additive realizes goal of the invention.Select suitable base oil, and base oil made with extra care, by refining moisture content, colloid and the harmful metal ion of removing in the base oil, improve the low-temperature cool starting performance of oil product, improve the stability of oil product and satisfy the index request of environment oil product burning back exhaust emissions; Select suitable binder component and content, by toluene, benzene mixed, methyl cyclopentadienyl three carbon back manganese, trimethyl phosphite 99, sodium hydroxide, oligopolymer, the compound mixing solutions of making additive of corrosion inhibitor, again the mixing solutions of additive is added in the base oil after refining to reconciling into methanol gasoline with certain adding proportion.Can not only bring into play original separately performance and effect after additive is compound, also can better bring into play the cooperative effect between binder component owing to its compatibleness produces certain synergy; Adjust the adding proportion of additive at the difference of basic oil composition and content, improve oil product anti-knocking property, reduce acid number, the corrodibility of oil product, increase the compatibility with other oil product, realize goal of the invention.
