Description of the Related Art Heavy fuels such as heavy oil and asphalt have a large amount of residual carbon content, and when they are burned by an external combustion engine such as a burner or a boiler or an internal combustion engine such as a marine diesel engine, unburned hydrocarbons (dust ) Tends to occur easily.
As a method to easily control the dust particles without improving the combustion equipment, there is a method such as increasing the amount of excess air to burn, but this method lowers the combustion efficiency and increases harmful nitrogen oxides. Will end up. Therefore, a method of adding an additive to the fuel has been adopted as a method for reducing the amount of dust without increasing the amount of air.

In order to solve these problems, an additive containing Ce, Nd, La and the like (Japanese Patent Laid-Open No. 1-256593) can be mentioned as an additive which can improve the effect of reducing the amount of dust with a small amount. However, although the rare earth element has a large auxiliary combustion effect, it has a drawback that it is expensive as compared with transition metals such as Fe, alkali metals and alkaline earth metals. Although alkali metal additives such as Na and K have a high combustion supporting effect, they are known to generate vanadium and low melting point compounds contained in heavy oil, and cause high temperature corrosion in exhaust systems and the like. In addition, among the alkaline earth metals, Ca, which has a relatively large effect and is inexpensive, has the drawback that the deposit has a strong adhesive force and is difficult to peel off.

The reason why the fuel additive of the present invention has a great effect of reducing dust particles is that Ce oxide has an oxygen pumping function for taking in and out oxygen, and that function promotes complete combustion of residual carbon. It is conceivable that the reaction rate may be further accelerated by the presence of Fe oxide. Further, the addition of Fe suppresses the crystallization of the produced carbon to a low level, so that residual carbon that is easily burned is formed. Due to these effects, it is considered that the combustion promoting effect is increased by combining Ce and Fe. Moreover, since Ce combines with vanadium in heavy oil to form a high-melting point compound, it also has an advantage of suppressing high-temperature corrosion due to combustion products.

Further, if Ce and Fe are combined, a great synergistic effect can be expected, but in both cases fine particles have poor dispersibility and there is a risk of sedimentation. Further, the probability that Ce and Fe exist in the vicinity is low, and a large synergistic effect cannot be expected. On the other hand, in the present invention, it is considered that the fine particles and the oil-soluble compound are adsorbed on the surface of the fine particles by the action of a surfactant like that of the fine particles and the fine particles and the oil-soluble compounds. There is almost no sedimentation, which is a drawback of the additive.

EXAMPLES The present invention will be described more specifically below with reference to Examples and Comparative Examples. The measurement and calculation method of the burning rate, the measurement method of the amount of dust and the conditions of the combustion furnace are as follows. [Measurement and Calculation Method of Burning Speed] 10 mg of fuel oil containing a fuel additive was used as a differential thermal balance (TG811 manufactured by Rigaku Denki KK).
0) was used to calculate the burning rate from the mass reduction curve of the produced residual coal when heated to 500 ° C. at a heating rate of 100 ° C./min and burned and held at 500 ° C. The air flow rate was 100 ml / min. (In this measuring device, if the flow rate is 100 ml / min or less, the diffusion rate of air becomes the rate-determining factor, and the measured value tends to fluctuate.) The combustion rate constant ks is calculated by the following equation.
