- a method for producing a hybrid coal slurry will be described in detail with the accompanying drawings.
- FIG. 1 is a conceptual diagram of a high-concentration hybrid coal slurry in which low-grade coal according to the present invention is advanced using a biomass-derived material.
- the coal hydrophilic surface is a ash surface of coal, and is a fixed carbon and volatile surface of coal having a -COOH (carboxyl group), -NH 2 (amine group), and -OH (hydroxyl group) functional group.

If the amount of biomass-derived material added to the weight of coal is less than 0.1% by weight, the amount of biomass-derived material penetrating into the hydrophilic surface of coal is insignificant, so that the hydrophilic surface of coal cannot be sufficiently coated so that the hydrophilic surface of coal is hydrophobically modified.

It may be referred to as a characteristic technical idea.
- the hybrid coal is homogeneous because the biomass-derived material penetrates into the pores of the coal and is physically chemically combined with the coal, as compared with the conventional non-uniform combustion characteristics by simply physically mixing the biomass and the coal.
- the degree of resorption of moisture after drying is lowered by blocking the pores of coal. Therefore, the more effectively the pores of coal are blocked, the less the resorption rate of water.
- the predrying is preferably carried out at 50 ⁇ 150 °C 0.1 ⁇ 24 hours. If the pre-drying temperature is less than 0.1 ° C for 50 ° C, it is difficult to completely dry organic solvents such as water, but the pore-filling effect of blocking pores of coal is insignificant. If it exceeds 150 ° C for 24 hours, Another increase in energy costs hinders efficiency.

- a high concentration hybrid coal slurry was produced.
- the weight ratio of alcohol / water was set to 0.01 to 0.99.
- the weight ratio of alcohol / water is less than 0.01, it is difficult to form a slurry, and if the weight ratio of alcohol / water exceeds 0.99, the wet gasification reaction does not occur, so it is preferable to maintain the weight ratio of alcohol / water in the range of 0.01 to 0.99.
- a dispersion medium of water / surfactant may be used by using a surfactant instead of alcohol, and the surfactant used at this time is usually used for the purpose of improving dispersibility in slurry production.
- CWM1002 (formaldehyde condensate of sodium naphthalene sulfonate), CWM1001 (polymer sulfonate), Na-CMC (carboxymethyl cellulose), Na-DBS (Alkylbenzene sulfate), Alkylsulfate sodium salt (Na-LS), alkylphenol ethyleneoxide (10) (NP1020), alkylphenol ethyleneoxide (50) (NP1060), CA1053 (casteroil ethyleneoxide (50)), ATLOX4913 (methyl methacrylate graft copolymer), cetyltrimethylammonium brimide or cetyltrimethylammonium chloride, etc.

- Sibeobu raw coal from Mongolia was prepared 100g of coal dried for 12 hours in an 110 °C oven.
- An aqueous sucrose solution was prepared in which 25 g of sucrose was dissolved in 100 g of water.
- Sucrose aqueous solution was added to the dried sibeobu coal to knead, and a composite of the sibeobu coal and the sucrose aqueous solution was obtained in the form of a paste.
- the obtained paste was placed in a reactor at 250 ° C. under a nitrogen atmosphere, and then dried and carbonized to prepare hybrid coal.
- Table 1 below shows the industrial analysis results and calorific value of Sibeobu raw coal and hybrid coal according to the preparation example.
- the hybrid coal had a lower calorific value (when considering the latent heat of high moisture content) of 570 kcal / kg and a higher calorific value of 350 kcal / kg, compared to Sibeobu raw coal. It can be seen that the calorific value is improved when manufactured with hybrid coal. In addition, since hybrid coal additionally contains artificial carbon formed from biomass-derived materials, the fixed carbon was found to be about 14.2 wt% higher than that of Sibeobu raw coal. More importantly than the fact that hybrid coal has a higher calorific value than Sibero coal, it is possible to maintain the calorific value of the hybrid coal for a long time because moisture is not resorbed.
- a viscosity and concentration measuring method through slurry production is generally used as a method for measuring the amount of water adsorbed on coal.
- the coal concentration of the slurry at an arbitrary viscosity is inversely proportional to the amount of water adsorption of coal. It is known that the lower the coal concentration in the slurry, the higher the water adsorption amount of coal. Therefore, the moisture of the hybrid coal of Examples 1 and 2 and the Sibeobu dry coal and Sibeobu raw coal of Comparative Examples 1 and 2 below. Adsorption amount could be confirmed by measuring the viscosity of the slurry prepared in the following examples, the results can be seen from FIG.

- a slurry was prepared in the same manner as in Comparative Example 1 except that the sibeobu dry coal of Comparative Example 1 was replaced with the sibeobu raw coal.
- Sibeobu raw coal from Mongolia was prepared 500g of coal dried for 12 hours in a 105 °C oven.
- a molasses aqueous solution in which 32 g of molasses was dissolved in 280 g of water was prepared.
- a molasses aqueous solution was added to the dried Sibeobu coal to knead to obtain a composite of Sibeobu coal and molasses aqueous solution in the form of a paste.
- the obtained paste was aged at room temperature and atmospheric pressure for 24 hours.
- the aged paste was subjected to predrying at 105 ° C. for 12 hours.
- the pre-dried paste was placed in a reactor at 250 ° C. under a nitrogen atmosphere to prepare hybrid coal by drying and carbonizing for 2 hours.
- Sibeobu raw coal from Mongolia was simply dried in an oven at 105 ° C. for 2 hours to obtain 500g of Sibeobu coal.
- the step of performing the preliminary drying step of Example 3 was omitted, and the aged paste was put in a reactor at 250 ° C. under a nitrogen atmosphere to prepare hybrid coal by drying and carbonizing for 2 hours.
- the Sibeobu simple dry coal was easily dispersed while absorbing water due to amphipathy, but in the case of hybrid coal after reforming, most of them were floating on the water despite strong stirring due to hydrophobicity. It could be observed. From this, it was confirmed that the hydrophilic pore surface of the hybrid coal was hydrophobically modified, and the resorption of moisture was suppressed.
- the coal concentration at the same slurry viscosity was higher in the order of hybrid coal> dry coal> raw coal, in particular, in the case of the hybrid coal according to the present invention, the coal concentration of the slurry was markedly high.
- the coal slurry concentration was 3000 cP
- the hybrid coal prepared in Example 1 showed a slurry concentration of 9.4 wt% higher than that of Sibeobu coal and 5.5 wt% higher than that of Sibeobu dry coal.
- the hybrid coal prepared in Example 2 showed a slurry concentration of 8.1 wt% as compared to Sibeobu raw coal and 4.2 wt% as compared to Sibeobu dry coal.
- the water added in the process of preparing the slurry is coated with the carbon component of the biomass-derived material and is inhibited from penetrating into the hydrophobicly modified hydrophilic surface.
- the artificial carbon component of the biomass-derived material filling the hydrophilic surface such as the ash hole, reduces the effective volume in which water can be absorbed, the absorption of water is reduced.
- Figure 4 shows the slurry calorific value change behavior according to the slurry viscosity change for each sample of Example 1, Comparative Examples 1 and 2. It was confirmed that the hybrid coal of Example 1 showed an extremely high slurry calorific value under the same viscosity condition as compared to the Sibeobu dry coal of Comparative Example 1 and the Sibeobu raw coal of Comparative Example 2. Therefore, when the hybrid coal slurry is used for the wet fractionation layer gasification, the gasification performance can be improved than when raw coal or dry coal slurry is used.
- Example 3 In order to evaluate the hydrophobicity of hybrid coal and simple dry coal prepared in Example 3 and Comparative Example 3, a disk of each coal sample was prepared and a contact angle measurement of water droplets on the surface of the disk was performed. Hybrid coal and simple dry coal are sieved with a powder of 100 ⁇ m or less and compressed to 50 atm to produce a disc having a diameter of 3 cm. Water droplets were dropped on the disks of the hybrid coal and the simple dry coal prepared in Example 3 and Comparative Example 3 to measure the contact angle with the disk surface, and the photograph is shown in FIG. 5. As shown in FIG. 5, the contact angle of the simple dry coal is 78.1 degrees, whereas the contact angle of the hybrid coal is significantly increased to 132.3 degrees.
- the hybrid coal of the present invention had a true calorific value (when considering the latent heat of high moisture content) of about 1450 kcal / kg, compared to Sibeobu raw coal, and the takeover calorific value generally used in power plants. It can be seen that about 1300 kcal / kg is higher, and the calorific value is greatly improved when manufactured with the hybrid coal of the present invention.
- the hybrid coal of the present invention additionally contains artificial carbon formed from the biomass-derived material, the fixed carbon was found to be about 13.4wt% higher than that of Sibeobu coal. More important than the fact that the hybrid coal produced in the present invention has a higher calorific value than the Sibeo raw coal, the resorption degree of moisture is significantly reduced, so that the calorific value of the hybrid coal can be maintained for a long time.
- Example 6 is Graph showing the pore size distribution of the hybrid coal prepared from Example 3 using a two-step drying step and Comparative Example 4 using a one-step drying step without the pre-drying step by introducing a predrying step of a paste containing a biomass-derived material. to be.
- the pore volume in the mesopore region of the hybrid coal of Comparative Example 4 is larger than the pore volume of the hybrid coal prepared from Example 3.
- Example 3 The coal prepared in Example 3 and Comparative Examples 3 and 4 was soaked in excess water to allow water to be adsorbed into the pores while stirring for 10 minutes, and then filtered for 20 minutes to remove external moisture and weighed. Moisture resorption rate was calculated as follows.
- Moisture resorption rate (wt%) (C wet -C dry ) / C dry * 100
- the hybrid coal produced from Example 3 using the two-step drying process had a resorbency rate of 30.74 wt% of water, and the moisture resorption rate of Sibeobu raw coal, which was simply dried at 105 ° C of Comparative Example 3 It can be seen that the re-adsorption rate of the hybrid coal prepared from Comparative Example 4 using 44.55 wt% and the one-step drying process showed a significantly lower value than 34.93 wt%.
- the hybrid coal manufactured by using the two-stage drying process of the present invention can maintain the high calorific value of the dry coal as it is, can be used as a fine fuel for power plants, and the generation efficiency compared to mixing low-grade coal containing intrinsic moisture There is an advantage that can be improved.
