Activated carbon is an adsorbent, catalyst and catalytic carrier. Each of its functions has a wide range of applications in industry. In terms of adsorption, it can adsorb various vapor substances, and it can also adsorb various substances in solution.

Of course, activated carbon is best at adsorbing organic matter, and it is much worse for inorganic matter. So some people call activated carbon a universal adsorbent. Although this statement is somewhat exaggerated, it is true. The catalytic properties of activated carbon make it widely used in industry.

Activated carbon is often used as a catalyst carrier in the chemical industry, and the catalytic active components are deposited on the surface of activated carbon by impregnation. Activated carbon not only plays the role of carrier in the catalytic process, because its pore structure characteristics, specific surface area and chemical properties will have a significant impact on the activity, selectivity and service life of the catalyst, so as a carrier it cannot be replaced by any other porous material.

How to choose high-quality and applicable activated carbon products?

Indicator parameters

Iodine adsorption value (iodine value 500-1200 mg/g): indicates the liquid phase adsorption capacity of activated carbon. The higher the iodine value, the stronger the adsorption capacity for liquid phase. Carbon tetrachloride adsorption rate (CTC40-120%): indicates the gas phase adsorption capacity of activated carbon. The higher the CTC, the stronger the adsorption capacity for gas phase. Methylene blue adsorption value (methylene blue value 5-18 ml/0.1g or 75-270 mg/g): indicates the decolorization ability of activated carbon. The higher the methylene blue value, the stronger the decolorization ability. Bulk specific gravity (0.45-0.55 g/L): The lighter the specific gravity, the more developed the pore structure of the activated carbon and the stronger the adsorption capacity. Other indicators: moisture, ash content, PH, caramel decolorization rate, strength, particle size, heavy metal content, etc., refer to the specific production process and use environment.  

Intuitive judgment

Look at the bubbles Put the activated carbon into the water, the bubbles of high-quality carbon are rich and the bubbles last for a long time. Look at the clarity When high-quality activated carbon is put into the water, the water quality is clear. Look at the appearance The raw carbon particles are uniform, the edges are clear, and there are no signs of use. Look at the volume Excluding the moisture content, the same weight of activated carbon, the larger the volume, the more developed the pore structure, and the better the adsorption capacity. Catalyst carrier activated carbon is mainly used in catalytic carriers, chemical industry, pharmaceutical synthesis, catalytic decomposition and other fields.

Catalytic carrier activated carbon uses imported coconut shells, sawdust, and anthracite as raw materials, and is refined by high-temperature steam activation production technology and process. It is mainly divided into granular and columnar. The product has the characteristics of developed pores, large specific surface area, good thermal stability, high mechanical strength, and reliable adhesion of the catalytic carrier.  

The catalyst is loaded on the activated carbon by immersing the activated carbon in an aqueous solution of metal salts. The activated carbon with more oxidizing functional groups on the surface is easy to load, and its performance as a carrier is determined by the pore structure and surface chemical structure. Catalytic carrier activated carbon Coconut shell activated carbon Catalyst carrier carbon series The catalyst that carries platinum, palladium and other platinum group catalysts on activated carbon has excellent catalytic performance for hydrogenation reactions, especially hydrogen-related reactions.

Activated carbon is impregnated with hydrogen oxidizing agent or NaOH for the purification of acidic gases.  

Copper, chromium and silver are impregnated on activated carbon to prepare anti-poison catalysts. Based on the evaluation of a large number of impregnated carbons, the following most commonly used and most effective compounds are selected, such as copper, silver, chromium, zinc, cobalt, manganese, vanadium and molybdenum compounds, as active components of carbon catalysts.   Palladium and platinum loaded on activated carbon is an important catalyst in industrial synthesis. Palladium and platinum supported on activated carbon are particularly suitable for reactions such as hydrogenation, dehydrogenation, dehydrogenation aromatization, cyclization and isomerization.
