There are many kinds of coal-based activated carbon for water purification, among which the commonly used are coal-based columnar activated carbon, coal-based granular activated carbon, coal-based powdered activated carbon, and coal-based spherical activated carbon.
Most of the coal-based activated carbon used for water purification is refined from selected anthracite coal as raw materials.activated charcoal wholesale supplier It has the characteristics of large specific surface area, developed pore structure, fast adsorption speed and easy regeneration. It is mainly used for benzene, toluene, xylene, and ether. , Alcohols, gasoline, trichloromethane, tetrachloromethane, acetone and other organic solvents, as well as hydrocarbon compound vapor recovery.
Activity means that the fluid mixture passes through the coal-based activated carbon bed, where the adsorbate is adsorbed. website After some time of operation, the fluid flowing out of the coal-based activated carbon bed begins to contain a certain amount of adsorbate, indicating that the coal-based activated carbon bed has lost its adsorption capacity At this time, the amount of adsorbate that has been adsorbed on the activated carbon is called the activity of the activated carbon.
Important data required for adsorption system. The standard practical method for determining the adsorption capacity of coal-based activated carbon by the liquid phase isotherm method can be used to determine the adsorption capacity of original and reactivated and powdered activated carbon.
