With the process of industrialization, people's demand for renewable resources is increasing. In this context, the furfural residue charcoal making process came into being, which has become an effective way to solve the two major problems of waste treatment and energy regeneration. Furfural residue, a common industrial waste, can be converted into high value-added carbon products after being treated by a carbonization furnace.
1. The ** and properties of furfural residue.
Furfural residue is mainly a solid waste generated in the process of refining furfural or furfuryl alcohol from biomass. It contains a large amount of organic components such as cellulose, hemicellulose and lignin, and has a high carbonization potential.
2. Furfural residue charcoal making process.
The furfural residue charcoal making process mainly includes two key steps: drying and carbonization.
Drying: This is the basis of charcoal making, and the moisture content of furfural residue is reduced through dehydration treatment to improve the carbonization efficiency. In the drying process, the control of temperature and time is very important, which directly affects the effect of subsequent carbonization.
Carbonization: In the anoxic or hypoxic environment, the dried furfural residue is treated at high temperature to decompose it into charcoal and gas. This is the core process of charcoal making, which requires control of carbonization temperature and oxygen content. In this process, the temperature level, heating time and atmosphere control will affect the quality and yield of the final carbon product.
According to the heating method and structural characteristics, the carbonization furnace can be divided into many types. Different types of carbonization furnaces have different advantages and disadvantages, suitable for different production scales and needs. For furfural slag, its material characteristics are small particle size, which is more suitable for drum carbonization furnace with continuous process, high production efficiency and large processing capacity.
3. Application of furfural slag charcoal.
Charcoal made from furfural residue can be used in a variety of fields. For example, it is used as a fuel in the industrial and civil sectors;It can also be used as a raw material for the manufacture of charcoal-based fertilizers. These applications not only enrich the use scenarios of furfural slag charcoal, but also enhance its economic value.
The R&D and application of furfural residue charcoal making process not only solves the problem of waste treatment, but also realizes the effective utilization of resources, which is in line with the current development concept of green, low-carbon and recycling.
