From an industry perspective, the two belong to different industrial fields. The former belongs to the forest chemical industry and the latter belongs to the coal chemical industry. At the same time, due to the difference in the downstream application fields of coal-based activated carbon and wood-based activated carbon, the downstream customers of wood-based activated carbon and coal-based activated carbon users are also different.granular carbon  The downstream users of wood-based activated carbon are mainly concentrated in food and beverage, medicine and other fields, while coal-based activated carbon The manufacturers' customers are concentrated in the chemical, printing and dyeing, sewage treatment and other industrial fields.

In the field of liquid phase adsorption: coal-based activated carbon contains heavy metals and ash content, and the product purity is relatively low. Because coal-based activated carbon is mainly produced by physical methods, the pores are mainly micropores, suitable for small molecule adsorption, and the application range is relatively narrow. Generally used in petrochemical, metallurgical, printing and dyeing, sewage treatment and other industrial fields in liquid phase adsorption;

The wood activated carbon has low ash content, less impurities, and is easy to purify. It is easy to adjust the pore distribution structure of the activated carbon under the chemical production process, and the micropores and mesopores are developed. Wood activated carbon is widely used, especially in fields such as food and beverage, medicine, which require high adsorption performance and high product safety requirements, and coal-based activated carbon cannot be replaced.

In the field of gas-phase adsorption: coal-based activated carbon products are strong and easy to recycle, so they are often used for gas-phase adsorption; wood-based activated carbon has low strength and is not traditionally used for gas-phase adsorption. However, with the advancement of technology and the improvement of production processes At present, the application of wood activated carbon has also been expanded to some emerging activated carbon gas phase adsorption fields such as oil and gas recovery, household air purification, etc., and as people pay more attention to health and environmental protection, the application space of wood activated carbon in the gas phase adsorption field will be further increase.yrdcarbon.com

From a long-term trend: raw coal resources are not renewable, coal-based activated carbon resources are limited and carbon dioxide emissions are greatly increased during the production process, so the price of coal-based activated carbon is increasing due to the cost of raw materials and environmental protection;

However, because the main raw material of wood activated carbon is the "three remnants" of forest products, it can be recycled, and the price of wood activated carbon is expected to decrease due to technological progress. Therefore, the long-term competitive advantage of wood activated carbon is higher than that of coal-based activated carbon.
