Professional Manufacturer biomass coconut shell activated charcoal making machine

Activated carbon is a specially treated carbon that heats organic raw materials (nut shells, coal, wood, etc.) to reduce non-carbon components without air (this process is called carbonization), then reacts with the gas and the surface is covered with air . Erosion, creating a microporous structure (this process is called activation). Since the activation process is a microscopic process, that is, the surface erosion of a large number of molecular carbides is point erosion, there are countless tiny pores on the surface of activated carbon. Most micropores on the surface of activated carbon have diameters between 2 and 50 nm. Even a small amount of activated carbon has a huge surface area. The surface area of activated carbon per gram is 500 to 1500 square meters. Almost all activated carbon applications are based on this characteristic of activated carbon.

Activated carbon is divided into coconut shell activated carbon, fruit shell activated carbon, wood activated carbon and coal activated carbon in terms of raw materials.
Activated carbon is divided into powdered activated carbon, granular activated carbon and special-shaped activated carbon based on the shape of the finished product.

The first process includes dehydration and carbonization. The raw materials are heated, dried at a temperature of 170 to 600°C, and approximately 80% of the original organic matter is carbonized. The second process is to activate the char. This is accomplished by reacting with charcoal using an activator such as water vapor. In the endothermic reaction, a mixed gas composed of CO and H2 is mainly produced, which is used to burn and heat the char to the appropriate temperature (800°C). to 1000℃) to burn out all decomposable substances, resulting in a developed microporous structure and huge specific surface area, thus having strong adsorption capacity

1. First: Use a dryer to dry materials . The raw materials of activated carbon generally come from materials containing high carbon content such as bamboo, hardwood, and persimmon shells. These raw materials are first dried and peeled to remove moisture and impurities.

2. Second: carbonization process . The processed raw materials are put into the carbonization furnace and treated with high temperature to convert them into raw charcoal. During this process, a certain temperature and oxygen content need to be maintained to ensure the carbonization effect. You can choose a continuous carbonization furnace or a horizontal carbonization furnace .

3. Third: activation process . After activation and carbonization, the organic matter in the raw material remains in the carbon micropores, causing the micropores to become clogged. Activating gas is introduced under high temperature conditions, and the water gas reaction occurs in the residual carbon in the absence of oxygen, which expands the micropores and obtains activated carbon with a porous structure.
There are many types of activated carbon, and their classifications are also different due to different raw materials, manufacturing methods, appearance, and usage occasions
