More particularly, the present invention relates to a hybrid fuel, apparatus and method for producing a hybrid fuel using the hydrophobic bio-fluid or oil, and more particularly, The present invention relates to a hybrid fuel, an apparatus, and a manufacturing method thereof using a hydrophobic biocide or oil having improved density and heating value.

Interest in coal as an energy source is rising again due to rising oil prices and distrust of nuclear energy stability. However, coal is the largest source of carbon dioxide in fossil fuels, which is a poor source of competitiveness given the global warming issue. As a result, the use of renewable energy is one of the issues that are currently being addressed globally as an energy source. This is due to the fact that the emission of carbon dioxide is reduced compared to conventional fossil fuels such as petroleum and coal, This is because it is attracting attention as an energy source. However, in Korea, when new or renewable energy sources such as solar or wind power are used for power generation or heating, land use and diffusion are limited due to differences in generation cost compared to fossil fuels.

On the other hand, the use of renewable energy is one of the issues that have been raised in the world as an energy source. This means that the emission of carbon dioxide is reduced compared to existing fossil fuels such as petroleum and coal, This is because it is attracting attention as an energy source. However, in Korea, when new or renewable energy sources such as solar or wind power are used for power generation or heating, land use and diffusion are limited due to differences in generation cost compared to fossil fuels.

Renewable Portfolio Standard (RPS) has been introduced since 2012, as Korea has been dealing with depletion of fossil fuels and the reduction of greenhouse gas emissions due to the international treaty, the Climate Change Convention. It is a burden to energy providers.

As a result, the power generation companies are attempting to reduce the generation of carbon dioxide in coal, and try to use IGCC and IGCC to combine coal gasification combined cycle (IGCC) and biomass (CCS) for the treatment of carbon dioxide is required to be installed at a cost of about KRW 1.3 trillion per unit, and it is very economically burdensome to install the carbon capture and storage (CCS) .

In case of biomass coexistence, there is a problem such as reduction of power generation efficiency due to combustion of biomass having a relatively low calorific value as compared with coal. That is, in the case of a fuel simply mixed with coal and oil-based biomass, the surface of the coal is coated with oil or oil is impregnated into the pores. However, due to the low surface tension of the oil itself and the lack of coupling between the oil-based biomass and the coal surface, the respective fuels, namely coal and biomass, maintain their original combustion characteristics and eventually exhibit different combustion characteristics. When this is applied to a power plant, oxygen is preferentially consumed excessively due to the low-temperature combustion pattern of the oil at the front of the burner. As a result, the amount of unburned carbon increases and the power generation efficiency is reduced do.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a hybrid fuel, an apparatus and a method for manufacturing the hybrid fuel using the hydrophobic biocide or oil. More particularly, the present invention relates to a hybrid fuel, And a method of manufacturing the hybrid fuel, apparatus and method using the hydrophobic biocide or oil, which exhibits the combustion characteristics of a single fuel by mixing at least one of them, and has improved density and calorific value.

In order to achieve the above object, there is provided a method for producing a hybrid fuel using a hydrophobic biocide or an oil, comprising the steps of: mixing a coal having a plurality of pores formed on a surface thereof with at least one of a hydrophobic bio- step; A second step of drying the mixture to form a hybrid fuel by impregnating a hydrophobic biocide or oil into coal pores present in the mixture; The present invention also provides a method for producing a hybrid fuel using the hydrophobic biocide or oil.

In the first step, the coal may contain more than 0 wt% and less than 100 wt% and at least one of the hydrophobic biocides or oils may be more than 0 wt% and less than 100 wt%.

The hydrophobic bioactive liquid may be any of animal oils such as palm oil, rape oil, soybean oil, jatropha oil, corn oil, coconut oil, sunflower oil, canola oil and all vegetable oils and their residues, And may include one or more.

The oil may comprise any or all of the light or heavy oil and residues thereof, including naphtha (gasoline), kerosene, light oil, heavy oil, etc., produced in the crude oil process.

In the first step, the hydrophobic biocides or oils may be heated or dissolved in a solvent and mixed with coal for even mixing.

In the first step, the solvent may be an organic solvent such as pure water, fresh water, nadir, brine, or a mixture of alcohol and water in the form of water, aliphatic hydrocarbons such as hexane; Aromatic hydrocarbons such as benzene, toluene, xylene and methylnaphthalene; Heterocyclic compounds such as quinoline and pyridine, ketones such as acetone, methyl ethyl ketone and cyclohexanone; Esters such as methyl acetate and methyl acrylate; Amines such as diethylenetriamine and N, N-dimethylaminopropylamine; Ethers such as diethyl ether, propylene oxide and tetrahydrofuran (THF); amides such as N-methylpyrrolidone (NMP), dimethylformamide and dimethylacetamide; And an organic solvent such as an aprotic polar solvent such as hexamethylphosphoramide, dimethylsulfoxide, and the like.

In the second step, the drying temperature range may be from 50 캜 to 350 캜.

And adding a surfactant to at least one of the hydrophobic biocides or the oil before the first step.

The surfactant is selected from the group consisting of LAS (sodium linear alkylbenzenesulfonate), AS (sodium alpha saffate), AOS (sodium alpha-olefin sulfonate), AES (sodium alkyl ether ester ester), POE (polyoxyethylene alkyl ether salt) , Synthetic surfactants such as SLS (sodium lauryl sorbate), SLES (sodium laureth sulfate), lauryl sulphate and sulphate, or synthetic surfactants such as coco betaine, lecithin, sorbilizer, sliver, emulsifying wax, , Natural surfactants such as montanov wax, olive oil wax, LES (sulfosuccinate), yuccaside gel, APG (alkylpolyglucoside), olive liquid, and the like.

The present invention also provides a hybrid fuel using a hydrophobic biocide or oil, which is produced by the above method.

The combustion characteristics of the hybrid fuel using the hydrophobic biocide or oil exhibit the combustion characteristics of a single fuel rather than the independent combustion characteristics due to the mixing of the fuel having different reactivity.

The present invention also provides an apparatus for producing a hybrid fuel using the hydrophobic biocide or oil, wherein the first step is performed in a mixer and the second step is performed in a dryer.

According to the hybrid fuel, the apparatus and the method of manufacturing the same using the hydrophobic bio-fluid or oil of the present invention, the hydrophobic bio-fluid or the oil is impregnated into the pores of the coal, thereby enhancing the binding force between the coal and the bio-fluid or oil. As a result, the hydrophobic bio-fluid or oil-impregnated coal, that is, the hybrid fuel, can be burned in a continuous pattern almost identical to the combustion pattern of coal.

Therefore, the hybrid fuel containing the bioc liquid or oil according to the present invention can burn in a continuous pattern almost the same as the combustion pattern of coal, thereby solving the problem that the power generation efficiency due to the generation of unburned carbon is inferior Since the surface becomes hydrophobic, moisture adsorption is reduced, and transportation cost can be reduced by removing water.

The coal used in the present invention may be any one selected from peat, lignite, bituminous coal, bituminous coal and anthracite.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a hybrid fuel, an apparatus and a method for producing the hybrid fuel using the hydrophobic biocide or oil according to the present invention will be described in detail with reference to the drawings.

The hybrid fuel according to the present invention comprises coal, biocide or oil. At this time, the bioliquid or oil is dissolved by heating or a solvent to have fluidity and then mixed with coal. When the solvent is used, the solvent is heated to remove.

At this time, coal has many pores on the surface. As the coal, peat, lignite, bituminous coal, bituminous coal or anthracite can be used, but the present invention is not limited thereto. In the present invention, hybrid fuels are basically produced in such a manner that low-grade coal having a moisture content of, for example, 20 to 60% by weight, such as lignite and sub-bituminous coal, is produced.

The biocide or oil is impregnated into the pores of the coal by the capillary phenomenon in the process of mixing the coal with the biocide or the oil and drying.

The bio-liquid is a hydrophobic bio-liquid containing all the vegetable oils and their residues including palm oil, rape oil, soybean oil, jatropha oil, corn oil, coconut oil, sunflower oil, canola oil, all animal oils such as tallow and fish oil, But not limited to, all biotic liquids having a hydrophobic surface such as waste oil.

And oils include, but are not limited to, all light or heavy oils and their residues and all types of oils, including naphtha (gasoline), kerosene, light oil, heavy oil, produced in the crude oil process.

A method of manufacturing a hybrid fuel according to the present invention will now be described with reference to FIG. 1 is a flowchart illustrating a method for producing a hybrid fuel according to the present invention.

First, in step S10, coal and biotic liquid or oil are prepared, and a coal-biotic liquid or a coal-oil mixture is prepared. For biogas or even mixing of oil and coal, the biocide or oil is heated to a certain temperature or melted in a solvent if necessary and mixed with coal. At this time, 0.1 to 100% by weight of the biocide or oil may be used based on coal.

In step S20, a biofluid or oil and coal are mixed and dried to produce a hybrid fuel. At this time, the hybrid fuel can be produced by mixing the coal pores sufficiently to impregnate the biosolution or oil into the pores, and then drying at 50 to 350 degrees.

The hybrid fuel produced by the manufacturing method according to the present invention exhibits combustion characteristics of a two-in-one fuel.

The combustion characteristics of the hybrid fuel according to the present invention can be confirmed through Examples and Comparative Examples. 2 is a graph showing a combustion pattern of a conventional raw coal and a bio-fluid. FIGS. 3 to 6 are graphs showing the combustion pattern of the hybrid fuel according to the present invention. The raw coal means unprocessed coal.

Referring to FIG. 2, berau coal is used as coal in the comparative example, and palm oil, palm pan oil, rapeseed oil and soybean oil are used as representative bioliquids and oils. It can be seen that each bioliquid and oil exhibit different combustion pattern from coal. The biosol has the lowest volatilization temperature for palm oil, while palm oil, rape oil and soybean oil have similar volatilization temperatures to coal.

In FIGS. 3 to 6, a hybrid fuel (HCK) obtained by mixing bio-liquid with raw coal was produced and combustion characteristics were evaluated. At this time, 10 weight%, 20 weight% and 30 weight% of biocides were used based on the dried raw materials.

Hybrid fuels produced from palm oil (Fig. 3), rape oil (Fig. 5) and soybean oil (Fig. 6) seem to maintain the existing coal combustion pattern irrespective of the amount of biologic added. This is because the volatilization temperatures of palm oil, milk and rapeseed oil are in the same region of burning temperature of coal.

That is, the palm oil, the rape oil, and the soybean oil according to FIGS. 3, 5 and 6 also show the combustion characteristics of the two-in-one fuel like the palm oil residue.

On the other hand, it can be seen that the peak of the hybrid fuel produced from the palm oil residue (FIG. 4) is around 200 degrees. Here, the peak of the combustion pattern occurring at around 200 degrees means the combustion of the palm oil residue, and the peak of the combustion pattern occurring above 300 degrees means combustion of the raw coal.

However, in the case of the hybrid fuel produced from the palm oil residue of FIG. 4, only a certain portion of the amount of biosol is volatilized at about 200 degrees. That is, a certain portion of the added bio-liquid is impregnated into coal pores and shows a combustion pattern such as coal, and an excessive amount of biotic liquid outside the coal pores maintains the existing combustion pattern.

Table 1 below shows the comparison of the fuel characteristics of raw coal and hybrid fuel.

When comparing the hybrid fuel with the raw coal, the analysis of industrial, element and calorific value for raw coal and hybrid fuel was carried out in order to confirm the degree of high quality, and the results are shown in Table 1.

Referring to Table 1, the As-received calorific value of hybrid fuels is at least 1300 kcal / kg higher than that of the raw coal. The elemental analysis showed that hybrid fuels tended to have higher carbon ratios and lower oxygen ratios than raw materials.

Table 2 compares the adsorption rates of hydrocarbons and hybrid fuels.

In order to evaluate the hydrophobic properties of the hybrid fuel, the adsorption experiments of the hydrocarbons were carried out.

Referring to Table 2, all coal samples were dried at 105 ° C for 24 hours prior to the experiment for accurate determination of the adsorption rate of water bran. A dry coal sample was added to the excess water and stirred vigorously for 20 minutes to induce water uptake into the coal pores. The agitated coal slurry solution is filtered for 15 minutes by using a filter paper having a pore size of 1 mu m to remove excess water and adhesion water on the coal surface.

Weigh the filtered coal sample and call it Wi. The filtered coal sample is dried again at 105 ° C for 24 hours and weighed after drying, which is named Wd. The water re-adsorption rate of the coal sample is calculated as follows.

Moisture re-adsorption rate = (Wi - Wd) / Wi × 100

In order to calculate the adsorption rate of hydrocarbons of raw and hybrid raw materials, the above equation was used to calculate the adsorption rate.

 Experimental results show that the adsorption rate of water bran is 6-13% lower than that of the hybrid fuel. This appears to be due to the lower hydrophobicity adsorption rate due to the strong hydrophobicity of the hybrid fuel surface.

As described above, since the surface of the hybrid fuel is highly hydrophobic and the water adsorption rate is low, it is possible to reduce the possibility of spontaneous ignition and to prevent the reduction of the calorific value due to the adsorption of the hydrocarbons.
