Advantages of Activated Carbon As Catalyst Carrier

When activated carbon is used as a carrier, its application range is much wider than that of activated carbon itself as a catalyst. Activated carbon can load precious metals, sulfides, halides, inorganic acids, etc. Among them, activated carbon is used to load rare precious metals. When activated carbon is used as a carrier, the general process is to first impregnate the metal salt and load it onto the activated carbon, and then heat the activated carbon loaded with precious metals. After high-temperature heat treatment, the corresponding metal oxide is obtained.

Activated carbon has the following advantages as a carrier: low price, stable acid and alkali resistance, developed pore structure, huge specific surface area and excellent adsorption performance. In addition, the precious metals loaded on activated carbon are easier to recover through the combustion of the carbon carrier, and the specific surface area, pore structure and surface functional groups of the activated carbon will affect the properties of the catalyst, and these parameters of the carbon carrier can be modified through physical and chemical treatments. 

The catalyst has a greater range of adjustment and adaptability, so activated carbon is increasingly used as a carrier. Coconut shell activated carbon is based on the iodine value of coconut shell activated carbon above 1,000, making its iodine value reach above 1,450. The catalyst is a very small carbon particle with a large surface area, and there are even smaller pores in the carbon particle - capillaries. This kind of capillary tube has strong adsorption capacity. Because the surface area of the carbon particles is large, it can fully contact the gas (impurities). When these gases (impurities) hit the capillary, they are adsorbed and play a purifying role. It is widely used as catalyst carrier in high-purity gas, liquid, and petrochemical industries. It can also be used for desulfurization, deodorization and other applications in the petrochemical industry.
