Electron-beam decomposition of vaporized VOCs in air

A study on electron-beam treatment was carried out to find out the effective decomposition conditions of vaporized volatile organic compounds. Air streams containing aromatic and aliphatic compounds were irradiated with electron beams in batch and flow systems. The research showed that chloroethene...

Description
Summary:A study on electron-beam treatment was carried out to find out the effective decomposition conditions of vaporized volatile organic compounds. Air streams containing aromatic and aliphatic compounds were irradiated with electron beams in batch and flow systems. The research showed that chloroethene was readily decomposed through a chain reaction with one of the fragmentation products, Cl radical. A thermal electron and negative oxygen ion were important active species for decomposing carbon tetrachloride. The formation of particles was observed only from the irradiation of aromatics, like benzene, xylene, and chlorobenzene. Dechlorination of chlorobenzene was enhanced in the presence of ammonia.
