主　　题：Photo-catalytic reactor Degradation Gaseous pollutant Paper mill 

摘      要：Volatile organic pollutants such as benzene and formaldehyde are commonly detected in the ambient air of paper *** remove these pollutants from the air,a photo-catalytic reactor was developed in this *** reactor had a series of honeycomb aluminum meshes coated with nanosized titanium dioxide as the catalyst for the degradation reactions of gaseous *** formaldehyde and benzene could be completely degraded in the ***,the degrading time for benzene was much longer than that for formaldehyde,and the degradation rate of benzene decreased with increasing initial benzene *** was found that the reaction pathway for formaldehyde in the mixture was different from that in its single component form,and it took about two times longer time to be degraded than that for its single component *** reaction pathway of benzene was similar in either case although the degradation time for benzene was about 50%shorter in the mixture form.
