“…Benzaldehyde was also reported as a by-product in previous works (Sun et al, 2009;Han et al, 2003). This benzaldehyde formation strongly suggested the involvement of the Russell's and Bennett's mechanisms associated with the peroxyl radicals (Kim et al, 2010). Other oxidation reactions might also occur as reported by Shepson et al (1984) and Atkinson (1985).…”

“…In order to solve the problem, some research groups have carried out works on decomposition of VOCs using hybrid technology such as combined EB or plasma with catalyst (Kim et al, 2010(Kim et al, , 2005(Kim et al, , 2004Jeon et al, 2008;Moon, 2003;Ogata et al, 1999;Kohno et al, 1998).

“…However, one of disadvantages associated with this technique is the formation of by-products (Kim et al, 2010;Sun et al, 2009;Jeon et al, 2008;Kim et al, 2005). In order to solve that problem, a few research groups have investigated the decomposition of VOCs using a hybrid technology such as combination of EB or plasma with catalyst (Kim et al, 2010(Kim et al, , 2005(Kim et al, , 2004Jeon et al, 2008;Ogata et al, 1999;Kohno et al, 1998). Therefore, the objective of this research is to review all the subjects covering EB for the decomposition of aromatic and aliphatic VOCs.…”

The removal characteristics for aromatic and aliphatic VOCs by electron beam (EB) were discussed in terms of several removal variables such as initial VOC concentration, absorbed dose, background gas, moisture content, reactor material and inlet temperature. It was reviewed that only reactor material was an independent variable among the potential control factors concerned. It was also suggested that main mechanism by EB should be radical reaction for the VOC removal rather than that by primary electrons. It was discussed that the removal efficiency of benzene was lower than that of hexane due to a closed benzene ring. In the case of aromatic VOCs, it was observed that the decomposition of the VOCs with more functional groups attached on the benzene ring was much easier than those with less ones. As for aliphatic VOCs, it was also implied that the longer carbon chain was, the higher the removal efficiency became. An EB-catalyst hybrid system was discussed as an alternative way to remove VOCs more effectively than EB-only system due to much less by-products. This hybrid included supporting materials such as cordierite, Y-zeolite, and γ-alumina.

Owing to the structural stability, modifiable acidity and abundant pores/channels, zeolite‐based materials can act as catalysts or supports for effective conversion of volatile organic compounds (VOCs). In this review, a series of VOC oxidation processes catalyzed by zeolite‐based materials will be introduced, which include thermal oxidation, photocatalytic degradation, plasma‐driven removal, catalytic ozonation, microwave‐assisted degradation and hybrid systems, where the specific roles, modification strategies and structure‐performance relationships of zeolites are discussed in depth. The following topics will also be covered, including the catalytic mechanisms of VOC oxidation, types of zeolite‐based materials in VOC catalytic oxidation, operation parameters in the processes, and reactor designs for efficiency optimization and cost control.
