Description

Activated carbon production device and process based on semi coke

Technical Field

The invention relates to the technical field of activated carbon production, in particular to an activated carbon production device based on semi coke.

Background

Activated carbon is a specially treated carbon produced by heating an organic raw material (husk, coal, wood, etc.) in the absence of air to reduce non-carbon components (this process is called carbonization), and then reacting with a gas to erode the surface and produce a structure with developed micropores (this process is called activation). In the preparation process, disordered carbon atoms and heteroatoms of the high-temperature activating gas with oxidability firstly react to open the originally closed pores, so that the surface of the basic microcrystal is exposed, and then the activating gas and the carbon atoms on the surface of the basic microcrystal continuously carry out oxidation reaction to continuously enlarge the pores. Some unstable chars are gasified to generate CO, CO2, H2 and other carbon compound gases, so that new pores are generated, and meanwhile, tar, non-carbonized substances and the like are removed, and finally, an activated carbon product is obtained.

When inorganic components in the semi-coke are carbonized and activated, most of the inorganic components are converted into ash, the ash can cause cracks on an interface where the ash is contacted with carbon, the strength of the activated carbon is influenced, the ash blocks gas from contacting with raw materials, the size distribution of semi-coke particles is uneven in the activation process of the semi-coke, when the particle size of the semi-coke is overlarge, the activation reaction is influenced by the diffusion speed of an activating agent in the carbon particles, the contact area of the activating agent and the carbon is small, the phenomenon that the outer part of the particles is burnt and the inner part of the particles is not activated can occur, and when the semi-coke particles are overlarge, the passing resistance of activated airflow is increased, and the purpose of uniform activation can not be achieved.
