Why use powdered activated carbon when making adsorption isotherms

The carbonization material of powdered activated carbon needs to be added into the activation tube of the activation furnace at intervals, and the superheated steam is fed into the reaction. The carbon is heated by the steam monotonously in the process of gradual decline, compensates for the carbonization, and then is activated. After all, it is cooled from the lower end. The discharge port is discharged at intervals. Explained below: The water vapor passes through the preheating chamber to be superheated to 300-400 degrees Celsius, and then is sent into the activated tube as the activation medium. It flows in parallel with the carbon from top to bottom, and continuously contacts with the carbon particles during the process of activity. A series of activation reactions turn into water gas at the lower part of the activation tube. The water gas is cooled together with the powdered activated carbon, and then separated in the separate section of the tube. The secondary air pipe sucks in air to achieve a satisfactory combustion demand, and the generated heat maintains the furnace temperature, so that the activation response continues. After the activated charcoal is cooled, it is sent to the ball mill with a belt conveyor for damage. The activated material on the conveyor belt is sucked into the ball mill by the suction of the exhaust fan, and impurities such as large sand and stone are left on the conveyor belt and removed. The fine carbon is sucked into the separator by the wind, and the coarse carbon is broken in the ball mill returned from the separator. The qualified carbon is sent to the cyclone separator with the wind for separation. The gas discharged from the cyclone separator is collected by the bag filter. After the powder is emptied, the charcoal collected by the cyclone separator and bag filter can be directly sold as a product. If users have higher requirements for the purity of powdered activated carbon, the collected activated carbon must be treated by pickling, watering and dehydration to remove some impurities such as iron salts and ash in the activated carbon. The dehydrated carbon contains 50% water. It can be sold as wet powder activated carbon. If you need to produce dry activated carbon, you need to dry it to reduce the moisture content to about 10%, which is a product of dry activated carbon. The steam activation process of powdered activated carbon is widely used, and the demand for powdered activated carbon is also great. The information and production process of powdered activated carbon determine the production and cost of powdered activated carbon, and also affect the competition in the market.

The carbon particles of 3-30 mm are selected as the activated materials. Broken, too fine carbon particles can be used as materials for producing granular activated carbon.
