Preparation method of high calorie material from wood tar {Preparation method of high calory material from wood-tar}

The present invention relates to a method for separating high-calorie material from molar tar, and more particularly, extracting molar tar with a solvent to obtain an extract; It relates to a method for producing a high calorie material from molar tar comprising the step of removing the solvent from the extract and a high caloric material prepared from molar tar by the same method.

The rapid development of science in the 20th century has made mankind more convenient than before the 20th century.

However, the development of science led to a more convenient life, but the development of science led to a more convenient life and mass production of environmental pollution. It is an important and sensitive topic.

Many researches are being conducted to solve environmental problems and human health problems. Among these findings, charcoal and wood vinegar have emerged as one of the solutions to such problems and are moving very actively in the industry.

Charcoal and wood vinegar are produced in the traditional charcoal kiln, and are classified into white and black coal according to the charcoal digestion system, and commercially available wood vinegar is obtained by cooling the smoke generated during the production process. On the other hand, charcoal and wood vinegar can be manufactured using a mechanical device rather than a charcoal kiln, which is distinguished from mechanical charcoal and wood vinegar, unlike the traditional method of charcoal and wood vinegar. The charcoal and wood vinegar produced in this way is in the limelight as a nature-friendly agricultural material for agriculture.

Meanwhile, when charcoal and wood vinegar are produced, smoke is generated during the manufacturing process, and when such smoke is cooled to produce wood vinegar, waste called moth tar remains. In the past, this tar was also used as an antiseptic, tire additive, and medicinal agent. However, with the recent development of better preservatives, tire additives, and medicinal preparations, the use of such tar tar has been greatly reduced and almost waste. Is treated as.

Some charcoal plants have moved to use this tar as fuel, but they need energy to solidify and remove moisture, and equipment for these treatments, so they use a different energy source than the cost of using tar as fuel. Because it is superior in terms of cost, practical use is not available. As a result, it is inconvenient to use mock tar as fuel and the calories for fuel are not superior to other fuel materials. Therefore, much research is still needed to use mock tar for fuel.

On the other hand, as mentioned above, since many environmental problems occur in modern times, many researches and / or attempts have been made to develop energy sources without causing environmental problems to mankind.

Therefore, many scientists are conducting worldwide research and practical use to obtain bioenergy such as bioethanol and biodiesel using natural resources such as wood and grains such as corn.

Thus, the inventors of the present invention have been conducted to obtain a component capable of producing high calories from the molar tar currently treated as waste as mentioned above, and extracting the molar tar as a solvent to obtain an extract; Including the step of removing the solvent from the above extract to find a method for producing a high calorie material from the tar tar was completed the present invention.

In addition, charcoal kilns and vinegar liquor manufacturers, which have to produce and process by-products of tar tar, sell motar tar, a material that can produce high-calorie substances, or sell high-calorie substances manufactured from moktar to companies that require high-calorie substances and local governments. It can also contribute to economic gains.

On the other hand, in the present invention, all solvents used to prepare high-calorie material from molar tar are low-boiling point general solvents, which are inexpensive and can be recovered in the present invention. The manufacturing method is very economically effective.

Wood has a calorific value of around 4,500kcal / kg, although it varies slightly depending on the species, and wood tar contains 25 to 45% of moisture. Although it varies depending on the method of making charcoal and wood vinegar, it is about 5,700 ~ 6,300kcal / kg. It has calories (see Table 1).

Calories of wood and tar (unit: kcal / kg) Kinds Calories (kcal / kg) wood About 4,500 Moktar 5,700-6,300 (6,000 avg)

&Lt; Example 1 >

Moth tar was extracted with a solvent for 45 minutes under a pressure of 25 ℃, 1 atm to obtain an extract.

Then, the solvent was removed from the above-mentioned moktar extract by a distillation under reduced pressure (40 ° C., 130 hpa) to prepare a high calorie material from moktar.

The solvent used was a mixed solvent in which hexane and alcohol were mixed in a volume ratio of 4: 6, wherein alcohol was used as ethanol.

<Example 2>

A high calorific material was prepared from moth tar in the same manner as in Example 1 except that a mixed solvent in which hexane and alcohol (ethanol) were mixed at a volume ratio of 5: 5 was used.

<Example 3>

<Example 6>

A high-caloric material was prepared from moth tar in the same manner as in Example 1 except that a mixed solvent in which hexane and alcohol (ethanol) were mixed at a volume ratio of 9: 1 was used.

<Test Example 1> Calorie change according to the composition ratio of the mixed solvent

The calorific value of the molar tar extract according to the mixing ratio of the mixed solvent for the molar tar extract isolated from the molar tar in Examples 1 to 6 was measured and the results are shown in Table 2 below.

As shown in Table 2 below, the lower the composition ratio of hexane in the mixed solvent, the higher the calorie content, and the lower the composition ratio of the alcohol, the lower the calorie tendency.

Heterogeneous hexane and alcohol at a volume ratio of 4: 6 showed 8,526 kcal / kg of calories and the highest calorie content. It is shown, but compared to the average calorie of 6,000 kcal / kg shown in Table 1 it showed a very high calorie.

In Examples 1 to 6, the calorie content of the tar tar extract separated from the tar tar is higher than that of the best charcoal (7,800 kcal / kg). Moreover, the separation and manufacture of the tar tar extract from the tar tar is mainly treated as waste. It is very encouraging in terms of its useful use of moth tar. In addition, the higher calorific value than wood-based fuel is considered to be noticeable in the high value-added use of wood materials, and it is very valuable in terms of manufacturing high value-added materials beyond the recycling of waste for wood tar treated as waste. It is considered a recipe. In addition, the effective use of waste is expected to play an important role in protecting the natural environment.

Test Example 2 Yield of High Calorie Material by Solvent Mixing Ratio

The yield of the molar tar extract according to the mixing ratio of the mixed solvent for the molar tar extract isolated from the molar tar in Examples 1 to 6 was measured and the results are shown in Table 3 below.

The yield of the wood tar extract according to the mixing ratio of the mixed solvent was measured by the content of the wood tar extract to the content of wood tar before the treatment ((wood tar extract content / wood tar content before treatment) × 100).

As shown in Table 3 below, when the mixing ratio of hexane is increased in the mixed solvent, the yield of high caloric material tends to increase, but in the mixed solvent where hexane: alcohol is mixed in a volume ratio of 8: 2, the yield of the highest molar tar extract is 10.2%. After showing, the yield was rather decreased even if the ratio of hexane in the mixed solvent was increased.

Therefore, the separation of molar tar, which is a high-calorie material, from the molar tar is considered to be very advantageous in terms of yield of the molar tar extract when using a mixed solvent with a hexane: alcohol ratio of 6-8: 4-2.
