March 15, 2024Sep 11, 2025

Characteristics of Different Activated Carbons：

Dimension of characteristics	coaly activated carbon	Wood activated carbon	Coconut shell activated carbon
Main aperture characteristics	The transition hole (middle hole) is relatively developed	The 2-5nm mesopore can be significantly increased by catalytic modification	The mesoporous structure can be optimized after modification
Specific surface area (m²/g)	Higher, usually 1000-1500	High, modified can reach 850-1150	High, modified can reach about 1000
Efficiency of adsorption of dioxins	Better (you need to select the model with developed holes)	High (significantly improved the removal efficiency of dioxin toxicity equivalent after modification)	High (the adsorption efficiency of gaseous dioxins can reach more than 96% after modification)
applicable scene	Waste incineration flue gas treatment (wide application)	Waste incineration flue gas treatment (modified with excellent performance)	Adsorption of dioxins in gas phase (high efficiency is shown in the study)
Other features	High mechanical strength, relatively moderate price	The adsorption capacity and rate of dioxins can be enhanced after modification	The source of raw materials is relatively limited and the price may be higher
matters need attention	The coal quality and carbon are different in different places and processes, so the mesopore size distribution should be paid attention to	The modification process (e.g., Fe(NO₃) ₃ catalysis) is crucial for the performance improvement	The modification process is crucial to the performance improvement
