Title : Removal of VOCs by hybrid electron beam reactor with catalyst bed
Electron beam decomposition of volatile organic compounds (VOCs) was
studied in order to obtain information for developing effective
treatment method of off-gases from industries. We have examined the
combination of electron beam and catalyst honeycomb which is either 1%
platinum based or ceramic honeycomb- based aluminum oxide, using
a hybrid reactor in order to improve removal efficiency and CO2
formation; and to suppress undesirable by-product formation e.g. O3,
aerosol, HxCy., and tar.
The experiments were conducted using a pilot-scale treatment system
(maximum capacity; 1800Nm3/h) that fitted the field size to scale up
from the traditional laboratory scale system for VOC removal with
electron beam irradiation.
Toluene was selected as a typical VOC that was irradiated to
investigate product formation, effect of ceramic and catalyst, and
factors effecting overall efficiency of degradation. Styrene was
selected as the most odorous compound among the VOCs of interest.
It was found that VOCs could be destroyed more effectively using a
hybrid system with catalyst bed than with electron beam irradiation
