Simultaneous removal of polycyclic aromatic hydrocarbons and soot particles from flue gas by gliding arc discharge treatment

摘要

The removal of Polycyclic aromatic hydrocarbons (PAH's) and soot particles from flue gas was studied using a gliding arc discharge reactor, and the flue gas was emitted from the polyethylene (PE) or polyvinyl chloride (PVC) combustion in a laboratory-scale drop tube furnace. The removal efficiencies have ranged from 70.3% up to 74.4%. The maximum removal efficiency of soot particles was up to 89.3%. Experimental results show that the technique can successfully remove PAH's and soot particles from flue gas, a possible mechanism is proposed to explain the experimental observations.
