However, if the temperature is raised rapidly using this method, organic plants (
A problem arises in that dry flowers (dried flowers) undergo rapid and significant decomposition, resulting in lower molecular weight, and the strength of the carbide decreases. Further, in order to prevent this, the above method requires a long time (10 hours) for carbonization, and the carbonization yield is not high.

It has been found that molecularization can be prevented, the strength of the resulting carbide can be increased, and the carbonization time can be shortened.

A method for producing a carbonized vegetable material, which comprises preliminary oxidation treatment at 300°C, followed by heating and carbonization in a non-oxidizing atmosphere. 2. 2. The method for producing a carbide of a plant according to item 1 above, which uses any one of nitrogen gas, argon gas, or hydrogen gas as the non-oxidizing atmosphere airflow.

度である。First, the dried plant is preoxidized prior to carbonization. Pre-oxidation can be carried out by placing the dried plant in a transparent quartz container or the like and heating it in the air at 200 to 300°C. If the heating temperature is lower than 200° C., oxidation takes time and sufficient oxidation cannot be achieved. Also, the heating temperature is 30
If the temperature exceeds 0°C, oxidation will proceed excessively, resulting in a significant decrease in weight and deformation, which is not preferable. Further, although the heating time and temperature increase rate are not constant depending on the size, type, etc. of the plant, the heating time is usually about 0.5 to 2 hours.
【0009】次いで、上記予備酸化での加熱温度を保持

Like the heating temperature during oxidation, the carbonization temperature in this case is not constant depending on the size and type of the plant, but it is usually about 600℃, and if necessary
In some cases, it may be heated to about ℃.

In addition, the carbonization time is significantly shortened, and excellent productivity can be achieved. Furthermore, since carbonization occurs under an air flow, air will not enter the container and cause oxidation, and decomposition products will be discharged outside the container, allowing a clean charred surface to be maintained.
