The adsorption of solute molecules in water by coal based granular activated carbon is a complex process, which is the result of several forces, including ionic attraction, van der Waals force and chemical hybrid force. According to the double rate diffusion theory of adsorption, the adsorption is a two speed process consisting of two stages of rapid diffusion and slow diffusion. The rapid diffusion is completed in a few hours, which gives full play to the adsorption capacity of 60% ~ 80% coal based granular activated carbon. Rapid diffusion is the process of solute molecules diffusing in the radial uniform distribution of macropores with small resistance. These macropores produce radial diffusion resistance. When the molecules diffuse from the macropore into the micropore which is connected with the macropore, they are very slow due to the great resistance caused by the narrow pore size. Micropores are also uniformly distributed in the carbon particles, but do not form radial diffusion resistance. The factors affecting the adsorption of coal based granular activated carbon involve the polarity, molecular weight and spatial structure of solute molecules, which depend on the characteristics of water quality. Coal based granular activated carbon has selective adsorption for different substances.
Waste gas treatment activated carbon is high quality Taixi coal and Jinshan coal as raw material, after crushing, carbonization, activation, refining and other strict process processing. It has the characteristics of large specific surface area, developed pore structure, reasonable pore distribution, strong adsorption capacity, uniform particle distribution and high wear resistance.Used for purification of chemical raw gas, chemical synthesis gas, pharmaceutical industry gas, beverage carbon dioxide gas and hydrogen, nitrogen, hydrogen chloride, ethyl hydrocarbon, ethane, cracking gas, inert gas, etc. It is also used to remove pollutants from the air and to separate and purify gas mixtures.
Wastewater treatment with activated carbon is high quality coal as raw material, after crushing, carbonization, activation, refined from. Reasonable void structure can effectively purify domestic sewage and chemical sewage.The rich specific surface area can also be applied to sewage bioculture bacteria, which is very suitable for bacteria to attach and multiply in large numbers.
Desulfurization and denitration
Desulfurization and denitrification products, columnar particles, black appearance, are made of high quality carbon raw materials, and add a certain proportion of adhesives, co-catalyst. After selection, ingredients, crushing, molding, drying, carbonization, activation and deep processing. The utility model has the advantages of high activity, high porosity, large sulfur capacity, high desulfurization efficiency and high mechanical strength. It has the advantages of good water resistance, low gas resistance, easy regeneration and not easy to break under high pressure. The product is mainly used for the removal of H2S in various gases such as biogas, water gas, semi-water gas, coke oven gas, natural gas, carbon dioxide, city gas, synthetic ammonia process gas, chemical raw gas and so on.
Solvent recovery and treatment of activated carbon, using high quality natural coal as raw material, refined by physical activation method, is black granular, non-toxic and tasteless, developed pores, three kinds of pore distribution is reasonable, strong adsorption capacity. It has a great adsorption capacity for most organic solvent vapors and is widely used in the recovery of organic solvents such as benzene, ethyl ether, xylene, ethanol, acetone, gasoline, chloroform and carbon tetrachloride over a wide concentration range.
