Absorption Tower

Types of Activated Carbon

	Carbon Briquet · Product produced by high pressure extrusion · Low pressure loss and high iodine value · Used for high concentration gas such as painting and drying facilities, solvent recovery facilities, etc.		Granular Activated Carbon · Relatively large surface area · Most commonly used activated carbon in the industry · Waste activated carbon can be recycled
	Powdered Activated Carbon · Mainly used to discolor, deodorize, remove bad taste and impurities of liquid materials · Suitable for water treatment		Impregnated Activated Carbon Activated carbon with a new function of physical adsorption, chemical reaction and catalysis by attaching chemical reactions and materials of catalysis in the normal activated carbon pores.

Duclean's Selecting Criteria of Activated Carbon

Iodine Value's Importance

Breakthrough Curve

Over time on the breakthrough curve, we can see that the toluene concentration increases and the iodine adsorption power decreases. Using activated carbon with high iodine value can increase activated carbon replacement cycle and its adsorption power.
