There are many types of coal-based activated carbon for clean water. The most commonly used ones are coal-based columnar activated carbon, coal-based granular activated carbon, coal-based powdered activated carbon, and coal-like spherical activated carbon.
Most of the coal-based activated carbon used for clean water is refined from selected high-quality bituminous coal. It has the characteristics of large specific surface area, prosperous pore structure, fast adsorption speed and easy regeneration. It is mainly used for benzene, toluene, xylene and ether. Recovery of organic solvents such as alcohols, gasoline, chloroform, tetrachloromethane, acetone, and recovery of hydrocarbon vapors.
The activity means that the fluid mixture passes through the bed of coal-based activated carbon, during which the adsorbate is adsorbed. After some time of operation, the beginning of the fluid flowing out of the bed of coal-based activated carbon exhibits a certain amount of adsorbate, indicating that the activated carbon bed of the coal is lost. In this case, the amount of adsorbate adsorbed on the activated carbon at this time is called the activity of activated carbon.
Important data required for the adsorption system. A useful and useful method for determining the adsorption capacity of coal-based activated carbon by liquid phase isotherm can be used to determine the initial and reactivated and powdered activated carbon.
According to the performance of the gas mask, the pore size distribution of activated carbon must be mostly microporous, so that it can be more suitable for adsorbing substances with small molecular diameter (toxic gas). If the pore width of the adsorption pore of activated carbon is smaller than the critical molecular diameter of the adsorbate, it belongs to Invalid pores, but too wide pores can only function as diffusion channels. Therefore, only the critical molecular diameter of the adsorbate is smaller than the pore width, and it cannot exceed a certain size requirement (according to various types of anti-virus) to achieve effective adsorption.

VIEW DETAILSFollowing the increase in environmental pollution, water use has been affected to varying degrees. In addition, the environment varies from place to place, making the water content of the day different. The use of "odor" in daily water, especially in drinking water, has become the cause of many areas plaguing residents. Honeycomb activated carbon manufacturers will handle this problem for us.
VIEW DETAILSThe shell activated carbon is a porous carbon material made of carbon-containing organic matter through carbonization and activation process. It has good selective adsorption force and is widely used in decolorization, water purification and other fields. It is an important chemical product in the national economy. First, the function of the shell activated carbon is extremely large.
