Competition of price difference between wood and columnar activated carbon

Time of publication: 09:50, October 29, 2020

Wood columnar activated carbon has the function of physical adsorption and chemical decomposition. In particular, benzene and formaldehyde can be absorbed in the air. The adsorption capacity is strong. Wood columnar activated carbon can quickly contact with harmful gases in the air, and firmly absorb harmful gas molecules through its own pores, making the air fresh and clean.

Columnar activated carbon has the characteristics of rich macropores, strong adsorption capacity and high strength. Because of the rich raw materials, the price of coal column activated carbon is lower in the same iodine value and the same quality of activated carbon products. For some industries with low requirements, the amount of wood activated carbon is a little too large. After all, the price of columnar activated carbon is relatively low, so it can be more favored by customers. Due to the high cost of raw materials, the production cost is high.

 Columnar activated carbon

The price of columnar activated carbon is higher than that of columnar activated carbon, with low impurity content, low ash content, high gas adsorption value, reasonable pore size distribution and fast adsorption speed. It has a long service life and is suitable for the occasions with high air purification requirements such as home, office and automobile. Although.

The price of columnar activated carbon is superior, but for the same iodine value and quality of columnar carbon, the adsorption capacity of coal is weak, the ash content of coal column carbon is higher than that of wood, and the specific gravity is relatively large. Powdered activated carbon (PAC) is produced by zinc chloride process with high quality sawdust and shell as raw materials. It has the characteristics of developed mesoporous structure, large adsorption capacity and fast filtration speed. Columnar activated carbon is made from high quality coal, coconut shell and sawdust through a series of production processes. Black cylindrical particles are widely used in gas treatment, sewage treatment, desulfurization and denitrification, solvent recovery, nitrogen generator, air separation equipment, painting workshop and other fields. In contrast, it is not much better than wood columnar carbon. In fact, it's not expensive or cheap, but we still buy the right products according to our own needs.
