The treatment of triphenyl waste gas using activated carbon.

"Three Benzene" refers to three types of toxic, flammable aromatic hydrocarbons: benzene, toluene, and xylene, which can explode when mixed with air. Their exhaust gases are commonly found in industries such as shoemaking, painting, and printing.
Activated carbon has three processes for adsorbing and purifying "Three Benzene" exhaust gases:
1. Activated carbon adsorption and desorption recovery.After activated carbon adsorbs a certain amount of pollutants, steam is used for desorption, followed by condensation separation to recover the solvent. This method is suitable for treating single-component exhaust gases, requires a large investment, and is not suitable for small factories.
2. Activated carbon adsorption catalytic combustion.After activated carbon adsorbs pollutants, hot air is used for desorption, and the desorbed pollutants undergo catalytic combustion. This process is suitable for treating large volumes of organic exhaust gases and does not cause secondary pollution. However, due to the thick layer of activated carbon, heat can easily accumulate and cause spontaneous combustion.
