preparation example Construction

[0043] The preparation method of the above-mentioned nano-fuel combustion-supporting agent comprises the following steps: in a water-bath thermostat, utilize a ball mill to rely on mechanical forces such as strong shearing\compression\impact of grinding media, add the following components (weight percentages) in sequence, and finally prepare Get nano-fuel combustion improver;

[0044] Nano-copper cerium and lanthanum complexes: 1.5-3.5%

[0045] Sorbitan Oleate: 20-35%;

[0046] Polyoxyethylene sorbitan oleate: 2.5%-5%

[0047] Copper-manganese acetylpropane complex: 2-4%

[0048] Succinimide: 2-3.5%

[0049] Fatty acid polyethylene glycol ester: 5% to 10%

[0050] Tween or Sibon: 1-3.5%

[0051] Isoamyl alcohol: 0.8-1.8%

[0052] Di-isooctyl phthalate: 15-25%

[0053] Calcium petroleum sulfonate: 1%

[0054] Kerosene or gasoline: balance.

[0055] The preparation principle shows that the self-made ball mill has a water-cooled interlayer, a variable-speed stirrer, and...

preparation Embodiment 1

[0057] Using a ball mill to combine the mechanochemical method with the chemical modification method, add dispersants, surfactants and accelerators, and neutral environment-friendly lubricants to the micron-sized copper cerium acetylacetonate and lanthanum complexes: 1.5-3.5%. Synthetic ester di-isooctyl phthalate: 15-25%, kerosene to prepare high-efficiency fuel combustion aids, and stably exist in fuel combustion aids. The dispersant is sorbitol oleate: 20-35%; polyoxyethylene sorbitan oleate: 2.5%-5%; acetylpropylene copper manganese complex: 2-4%; succinimide: 2-3.5% %; fatty acid polyethylene glycol ester: 5% to 10%; calcium petroleum sulfonate, etc. The surfactant is a mixture of Siben-20, Siben-80, Tween-40, Tween-60 and the like. The accelerator is isoamyl alcohol. Dispersant 15ml, surfactant 500ml, accelerator 1600ml, environment-friendly lubricant—synthetic ester di-octyl phthalate: 6400ml; grind at 1200rpm, 75°C for 15 minutes, add 160 grams of micron-sized acetyl...

preparation Embodiment 2

[0059] In the ball mill, the micron-sized copper acetylacetonate cerium lanthanum complex (as a dispersion item) was added. With the increase of crushing, the particle size is refined; the degree of particle dispersion increases, and the aggregation speed between particles also increases. When the crushing speed and aggregation speed of the material are equal earlier, the crushing and dispersion reach a dynamic balance. Micron-sized copper cerium acetylacetonate Lanthanum complexes cannot be pulverized finer. However, if the crushing speed of the material can be greatly improved by strengthening the pulverization, the enhanced dispersion method of forming a "core-shell" structure can also be adopted to reduce the aggregation speed between particles, and the micron-sized copper cerium lanthanum acetylacetonate complex can It is crushed finer and reaches the nanometer level. Appropriate grinding time; appropriate stirring speed; optimum content of nano-additives, appropriate mo...

Abstract

The invention discloses a nanometer fuel combustion adjuvant and a preparation method thereof. In a water bath thermostatic bath, through utilizing the mechanical acting forces of a ball crusher, such as scissoring / compressing / impinging and so on, the following components (weight percentage) are added in sequence: 1.5 to 3.5 percent of nanometer acetylacetone cerium and lanthanum composition, 20 to 35 percent of sorbitan oleate, 2.5 to 5 percent of polyoxyethylene sorbitan oleate, 2 to 4 percent of acetylacetone and manganese composition, 2 to 3.5 percent of succinimide, 5 to 10 percent of fatty acid polyethylene glycol ester, 1 to 3.5 percent of tween or span, 0.8 to 1.8 percent of isoamyl alcohol, 15 to 25 percent of diisooctyl phthalate, 1 percent of calcium petroleum sulfonate, and the rest of kerosene or petroleum. The nanometer fuel combustion adjuvant is added into the fuel in the proportion of 1:(150-250), and the rate of economizing fuel of a single cylinder tractor is 8 to 14 percent, the rate of economizing fuel of a diesel locomotive or a dead oil boiler is 8 to 16 percent, and the rate of economizing fuel of a gasoline engine is 6 to 10 percent.

Description

technical field [0001] The invention relates to a fuel oil combustion rate can be greatly improved, emissions of pollutants CO X , NO X Greatly reduced nanometer fuel combustion enhancer and preparation method thereof. Background technique [0002] Existing vehicles, ships, and industrial boilers all use diesel oil, gasoline, or heavy oil as fuel. During the combustion process of the fuel, due to the short combustion time in the internal combustion engine or boiler, the combustion is incomplete, so the tail gas contains some incompletely combusted substances, such as Hydrocarbons, carbon monoxide, nitrogen oxides and other toxic substances. This not only causes waste of energy, but also seriously pollutes the environment. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a nano combustion accelerant which can fully burn the fuel and reduce the emission of pollutants after combustion and its preparation method. ...
