Abstract

PURPOSE:To obtain a carbide having high strength in high yield by previously oxidizing a plant before carbonization of plant to prevent the formation of low-molecular weight substances resulting from rapid and extreme decomposition of the plant, successively heating and carbonizing the plant in a gas flow under a nonoxidizing atmosphere. CONSTITUTION:For example, flowers (small branches or leaves) of rose, Camellia sasanqua Thunb., or rose of Sharon or fruits of Japanese chestnut with bur are dried. The dried plants are previously oxidized at 200-300 deg.C, heated in a gas flow under a nonoxidizing atmosphere using a gas of N2 gas, Ar gas or H2 gas and carbonized to give a carbide of plant. This method provides a carbide having excellent strength in a relatively high yield, extremely shortens a carbonization time and shows excellent productivity. Since plants are carbonized in the gas flow, air is not fed into a container, will not cause oxidation, the decomposition products are discharged out of the container and clean surface of the carbide can be maintained.

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.

[Effects of the Invention] According to the present invention, by pre-oxidizing prior to carbonization, it is possible to obtain a carbonized product with excellent strength at a relatively high carbonization yield by preventing the rapid and drastic decomposition of organic matter from plants. 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.
