  An embodiment of the present invention which is considered to be suitable will be briefly described with reference to the drawings showing the operation of the present invention.

  The inventor, for example, uses charcoal husk charcoal as a carbonized porous plant material for liquid adsorbents, anti-slip materials, excrement disposal materials, soil improvement materials, humidity control materials, deodorizing materials, or filtrations that require hydrophilicity. Considering the application to the wood, we focused on the hydrophilicity of the rice husk charcoal.

  When rice husk charcoal produced by existing carbonization equipment (badge-type carbonization equipment that performs carbonization in a low-oxygen atmosphere by making the carbonization part a sealed space) is thrown into water, rice husk charcoal immediately sinks into the water , Hydrophilic rice husk charcoal) and rice husk charcoal (hereinafter referred to as water-repellent rice husk charcoal) that does not sink in water and has the opposite property. There is also rice husk charcoal (hereinafter referred to as semi-hydrophilic rice husk charcoal) that floats on the water surface in a half-sunk state.

Therefore, the carbon content of the rice husk charcoal was considered to be largely related to the hydrophilicity and water repellency, and the carbon contained in the rice husk charcoal was examined (Experiment 1) .

  That is, as a result of measurement by Fourier transform infrared spectroscopy, carbon was graphite.

  Since this graphite has extremely high water repellency, it has been found that the difference in carbon content in each rice husk charcoal greatly affects hydrophilicity and water repellency. Therefore, it is possible to distinguish between hydrophilic husk charcoal and water-repellent husk charcoal based on the graphite content.

Next, the graphite content per gram of rice husk charcoal in hydrophilic rice husk charcoal and water-repellent rice husk charcoal was examined (Experiment 2 ).

  Specifically, as a result of calorific value analysis, the calorific value per gram of hydrophilic rice husk charcoal is 16,060 J / g, and the calorific value per gram of semi-hydrophilic rice husk charcoal is 16,760 J / g. The calorific value per 1 g of water-repellent rice husk charcoal was 19,020 J / g.

Above experiments 1 or al, difference the heat value is the difference of the graphite content was calculated graphite content per rice husk charcoal 1g as follows.

  Since the calorific value of graphite is 394 kJ / mol and the atomic weight of carbon 1 mol is 12, it is 394 kJ / mol per 12 g and 32,800 J / g per 1 g. Based on this, hydrophilic rice husk charcoal, quasi-hydrophilic rice husk The graphite content per gram of charcoal and water-repellent rice husk charcoal is obtained as follows.

<Hydrophilic rice husk charcoal>
(Heat generation amount per gram of hydrophilic rice husk charcoal 16,060 J / g) ÷ (heat generation amount per 1 g of graphite 3,2800 J / g) = 0.489 g (graphite content per gram of hydrophilic rice husk charcoal)
<Semi-hydrophilic rice husk charcoal>
(Calorific value 16,760 J / g per gram of semi-hydrophilic rice husk charcoal) ÷ (calorific value 32,800 J / g per gram of graphite) = 0.510 g (graphite amount per gram of semi-hydrophilic rice husk charcoal)
<Water repellent rice husk charcoal>
(Heat value 19,020 J / g per gram of water-repellent rice husk charcoal) / (heat value 32,800 J / g per gram of graphite) = 0.579 g (graphite amount per gram of water-repellent husk charcoal)

Next, as a result of examining the water absorption rate when the moisture content of the hydrophilic rice husk charcoal and the water-repellent rice husk charcoal was set to substantially the same state (Experiment 3 ), the hydrophilic rice husk charcoal was about 1. It was confirmed that water was absorbed 7 times more.

From the above Experiments 1 to 3 , the present inventors found that the difference between hydrophilic rice husk charcoal and water-repellent rice husk charcoal is the difference in graphite content having water repellency, and as a result of repeating various experiments, It was confirmed that a rice husk charcoal with a graphite content of less than 0.5 g per 1 g of this rice husk charcoal is suitable for hydrophilic rice husk charcoal, and that with a graphite content of 0.5 g or more per gram of rice husk charcoal is suitable for water-repellent rice husk charcoal. .

  Therefore, when the rice husk charcoal with a graphite content of less than 0.5 g per gram of the rice husk charcoal is used as the main raw material, the liquid adsorbent, anti-slip material, excrement treatment material, soil improvement material, humidity control material that are required to absorb water , It is extremely useful as a hydrophilic member used in a deodorizing material or a filtering material.

Further, in the present invention , when producing rice husk charcoal which is a main raw material for the hydrophilic member, when carbonizing the rice husk in the carbonization processing unit 1, the gas generated in the carbonization processing unit 1 is removed from the carbonization processing unit 1 outside. Force exhaust to.

  When the graphite content of the rice husk charcoal thus obtained was examined, it was confirmed that the graphite content was less than 0.5 g per gram of rice husk charcoal.

  This is because graphite is present in the gas generated in the carbonization processing unit 1 and forcibly exhausting this gas out of the carbonization processing unit 1 prevents the graphite from adhering to the rice husk charcoal. If the gas is not forcibly exhausted from the carbonization unit 1, when the produced rice husk charcoal is cooled together with the gas, the graphite in the gas adheres to the rice husk charcoal. In this case, the rice husk charcoal has water repellency. become.

  Therefore, by forcibly exhausting the gas generated in the carbonization part 1, rice husk charcoal having a low graphite content, that is, rice husk charcoal having excellent hydrophilicity as a main raw material of the hydrophilic member can be easily and reliably obtained. As a result, this carbonization method of rice husk is extremely excellent as a technique capable of separately producing hydrophilic rice husk charcoal and water-repellent rice husk charcoal.

  A specific embodiment of the present invention will be described with reference to the drawings.

  The present embodiment is a hydrophilic member used as a liquid adsorbent, anti-slip material, excrement treatment material, soil improvement material, humidity control material, deodorant material or filter material, for example, carbonized porous plant material The rice husk charcoal is used as a main raw material, and the graphite content of the rice husk charcoal is less than 0.5 g (0.489 g) per 1 g of rice husk charcoal.

  As described above, rice husk charcoal having a graphite content of less than 0.5 g per gram of rice husk charcoal has excellent hydrophilicity, and as described above, it is extremely useful as rice husk charcoal as a main raw material for the hydrophilic member.

  In this embodiment, the hydrophilic member is composed of 100% rice husk charcoal, but other materials may be mixed with rice husk charcoal to form a hydrophilic member.

  In addition, rice husk charcoal having a graphite content of less than 0.5 g per gram of rice husk charcoal includes an appropriate oxygen scavenger (for example, Ageless (registered trademark) manufactured by Mitsubishi Gas Chemical Co., Ltd.) and an appropriate desiccant (for example, AGC ES It is preserved by storing it in a container that does not vent together with Hishibeat (trade name) manufactured by ITEC Co., Ltd. and sealing it.

  The container is a bag (such as a bag made of barrier nylon / polyethylene, a bag made of polyethylene terephthalate / aluminum / polyethylene, manufactured by Meiwa Packs Co., Ltd.) made of a member that does not have air permeability (synthetic resin, metal, etc.), and has an opening. After storing a predetermined amount of rice husk charcoal, oxygen scavenger, and desiccant from the part, the opening is sealed (heat fusion). When closing the opening of the container, in some cases, the oxygen absorber and the desiccant may not be stored and the container may be simply sealed, or the container may be vacuum-treated or filled with an inert gas. May be.

  In addition, when the container is vacuum-treated (vacuum packed), it is possible to prevent as much as possible the deterioration in performance as a hydrophilic member due to sucking moisture in oxygen, which is a concern when oxygen is present in the container. Of course, the movement of rice husk charcoal in the container can be prevented, and the husk charcoal which is feared by the movement of rice husk charcoal in the container can be prevented as much as possible.

  Further, the container has antistatic properties. It has been confirmed that the above-mentioned materials are not charged with static electricity enough to ignite oil.

  For example, in a scene where oil is adsorbed (for example, an accident site or a gas station), there is a concern that the oil to be adsorbed may be ignited by static electricity charged on a member brought to the site.

  In this regard, this embodiment is extremely useful since the container has antistatic properties, and there is no fear of an electrostatic fire in which oil is ignited by static electricity.

  The container is not limited to a bag but may be a box-shaped body.
