Hemp plants have porous and hollow structures and high lignin content, especially the lignin content of jute stalks as high as 23%. The prepared activated carbon has unique physical and chemical adsorption properties, which can increase the added value of the hemp industry. When carbonizing jute stalks, you need to pay attention to the following aspects:

1. Temperature control: Different temperatures will affect the quality of charcoal. Excessively high temperature and too long time will cause excessive carbonization of jute stalks, making them brittle, hard and brittle, affecting the use effect. Therefore, when carbonizing jute stalks, it is necessary to choose the appropriate temperature according to the actual situation.

2. Carbonization time: It is equally important to determine the appropriate carbonization time. The length of carbonization time will also have an impact on the properties of charcoal. Typically, carbonization time will vary based on temperature and the nature of the original material.

3. Airtightness: During the carbonization process, maintaining the airtightness of the carbonization furnace helps to control the internal temperature and atmosphere and ensure the stable progress of the carbonization process. A properly designed carbonization furnace can prevent outside oxygen from entering, thereby preventing the charcoal from burning instead of carbonizing.

4. Atmosphere control: Controlling the atmosphere in the carbonization furnace is one of the keys to ensuring the carbonization effect. An oxygen-deficient or low-oxygen atmosphere is often used to prevent complete combustion of the wood and instead allow for a carbonization reaction.

5. Emission treatment: During the carbonization process, some gas and liquid emissions may be produced. These emissions must be dealt with in compliance with regulations to ensure no negative impact on the environment.

Hemp charcoal has the characteristics of uniform carbonization, light specific gravity and rapid combustion. It is used in many industries, including military fuses, rubber, plastics, environmental protection, brewing, fireworks, firecrackers, medicine and other fields. It has a wide range of uses and functions. big.
