Description

Water-based hydrogenated diesel fuel additive

The present invention relates to the employed additive of a kind of synthol, particularly make the water-base diesel-oil synthol.

The shortage of petroleum resources at present, various synthols produce in succession, a lot of with alcohols for the test of oil, the someone proposes to replace diesel oil with water recently, manufacture water-base diesel-oil, its key is to select a kind of catalyzer or claim additive, makes two kinds of immiscible liquid of water and diesel oil that chemistry, physical change take place rapidly and becomes a kind of new synthol.Chinese patent 94101470.3 water and diesel oil synthol catalyzer and manufacture method thereof, Chinese patent 94108047.1 water-base diesel-oil additives and manufacture method and application is characterized in that or catalyst for additives, ignition dope, antioxidant, pour point depressant and lubricant are formed.The shortcoming of above-mentioned additive or catalyzer is that the water-base diesel-oil low temperature with its manufacturing becomes sticky easily, solidifies, in the transportation oil product produce static, may presence of fire or explosion hazard, dangerous.

The objective of the invention is to propose a kind ofly to have, the water-based hydrogenated diesel fuel additive of antistatic and peace and quiet function, it make the water-base diesel-oil synthol be difficult for solidifying, antistatic, have remove that engine chamber and piston face form add film and carbon deposit.

The present invention realizes like this.A kind of water-based hydrogenated diesel fuel additive comprises catalyzer, ignition dope, antioxidant, pour point depressant, it is characterized in that also containing purification agent, static inhibitor, anti-icer and anti-wear agent, and its composition is by weight percentage:

Catalyst S ₈₀83.6%～86.4%;

Antioxidant di-tert-butylphenol 1.8%～2.2%;

Anti-wear agent alkyl sulphur ortho acid fat 1.8%～2.2%;

Borated alkyl naphthalene sulfonate barium 1.8%～2.2%;

Anti-icer ethylene glycol monomethyl ether 1.8%～2.2%;

Static inhibitor chromium stearate 1.8%～2.2%;

Pour point depressant alkylnaphthalene 1.8%～2.2%;

Ignition dope sulfonated petro-leum 2.8%～3.2%.

Catalyst S wherein ₈₀Useful catalyst T ₈₀Substitute, antioxidant di-tert-butylphenol available oxidant 2-naphthylamines substitutes, and anti-quiet dose of chromium stearate can be used antistatic agent C _18-20Lipid acid chromium substitutes.

Having increased static inhibitor in the additive of the present invention, is because oil product is carried in pipeline, if transfer rate is very high, and then may be owing to the oil product friction produces static.Because the conductance of oil is very low, static can not in time discharge and accumulate, and can lead to fire and explosion hazard, adds the electric conductivity that static inhibitor can increase substantially oil product in the oil, reduces the electrostatic accumulation.

Increased anti-icer and be because the water-base diesel-oil of making, owing to contain a large amount of water, these moisture can be tied water, thereby stop up oil rectifier, cause the accident, and add just blockage phenomenon no longer of anti-icer.

Increased purification agent and be because behind the fuel oil combustion, form paint film and carbon deposit on the combustion chamber of engine and piston face, this needs in time to remove, otherwise reduces motor efficiency greatly, removes so added purification agent.

Having increased anti-wear agent is the synthol of making for this additive, when not having sintering, can obviously reduce wearing and tearing, when burning, can improve sintering load.

Most preferred embodiment of the present invention consists of: by weight percentage

Catalyst S 80 85%;

Antioxidant di-tert-butylphenol 2%;

Anti-wear agent alkyl sulphur ortho acid fat 2%;

Borated alkyl naphthalene sulfonate barium 2%;

Anti-icer ethylene glycol monomethyl ether 2%;

Static inhibitor chromium stearate 2%;

Pour point depressant alkylnaphthalene 2%;

Ignition dope sulfonated petro-leum 3%.

The manufacture method of this additive is as follows:

With catalyzer, antioxidant, anti-wear agent, purification agent, anti-icer, static inhibitor, pour point depressant and ignition dope, be mixed into emulsion liquid according to the above ratio and get final product.

Water-based hydrogenated diesel fuel synthol with the manufacturing of this additive, even chemistry, physical change, formation water-in-oil type emulsion, good stability take place rapidly in two kinds of immiscible liquid of water and diesel oil, do not precipitate, low temperature does not solidify, do not tie water, have peace and quiet function, antistatic, efficiency of combustion is high.
