“…V 2 O 5 /TiO 2 -based catalysts, which are commercially employed for the reduction of NO x via NH 3 -SCR, have also been found to be active for the oxidation of PCDD/Fs [2,3]. The kinetics of the oxidation of chlorinated aromatic compounds over these systems have been studied by several groups [1,[4][5][6][7].…”

“…Therefore, a great effort has been made for the reduction/ elimination of the PCDD/Fs emission, and selective catalytic reaction (SCR) technology has been considered as the most promising one for its excellent selectivity towards the formation of small molecules such as H 2 O, CO 2 , and HCl, in which the development of highly efficient catalysts is one of the key topics involved [2][3][4]. In the recent decades, several series of catalysts have been optimized for industry applications, for example, MnO x based catalysts [5][6][7][8], noble metal catalysts (mostly Pt-based) [9][10][11], and perovskites such as LaFeO 3 and LaMnO 3 [12,13]. Particularly MnO x is reported to possibly promote the chlorobenzene (CB) oxidation at relatively low temperatures [7,8].…”

Catalytic Oxidation of Chlorobenzene over MnO x /Al2O3-carbon Nanotubes Composites

MnO x /Al 2 O 3 -carbon nanotubes (CNTs) composites prepared by hydrothermal method were characterized by XRD, SEM, TEM, TGA, BET, XPS and H 2 -TPR. Catalytic oxidation of chlorobenzene (CB) was conducted over the composites under gas hourly space velocity (GHSV) of 36000 h -1 and CB concentration of 2800 ppmv. For the catalyst with approximately 25 wt% CNTs and 10 at.% Mn, CB removal efficiencies reached up to 83.3 and 97.7% at 150 and 300°C, respectively. Moreover, no Cl species was detected over the used MnO x / Al 2 O 3 -CNTs catalyst implying that the release of chlorine element from the catalyst surface was facilitated by CNTs introduction.

“…Catalytic oxidation represents the current state of the art technique used commercially for the destruction for PCDD/PCDFs. In particular, V 2 O 5 /TiO 2 -based catalysts, employed in most incinerators for the control of NO x emissions via the selective catalytic reduction with NH 3 , are also active for the oxidation of PCDD/PCDFs [3][4][5][6][7]. In addition to PCDD/PCDFs and NO x , incinerator flue gas streams also contain complex mixtures of both halogenated and non-halogenated volatile organic compounds (i.e., biphenyls and polyaromatic hydrocarbons [8]).…”
