Remediation of PCB-contaminated soil using a combination of mechanochemical method and thermal desorption
The combination of mechanochemical method and thermal desorption for remediating polychlorinated biphenyls (PCBs) in contaminated soil was tested in this study. The effects of grinding time and heating time on...

Effects of bypass system on PCDD/F emission and chlorine circulation in cement kilns
A bypass at the kiln inlet allows the effective reduction of alkali chloride cycles and thus perhaps affects the emission of PCDD/Fs. Effects of bypass system on PCDD/F emission and chlorine circulation were s...

Low temperature destruction of PCDD/Fs over V2O5-CeO2/TiO2 catalyst with ozone
Catalytic destruction of PCDD/Fs (polychlorinated dibenzo-p-dioxins and furans) over V2O5-CeO2/TiO2 catalyst was investigated at a low temperature range of 140–180 °C, in the absence and presence of ozone (200 pp...

Suppression of dioxins by S-N inhibitors in pilot-scale experiments
S-N inhibitors like thiourea and sewage sludge decomposition gases (SDG) are relatively novel dioxins suppressants and their efficiencies are proven in numerous lab-scale experiments. In this study, the suppre...

Catalytic destruction of PCDD/Fs over vanadium oxide-based catalysts
Vanadium oxide-based catalysts were developed for the destruction of vapour phase PCDD/Fs (polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans). A vapour phase PCDD/Fs generating system was des...

Emission and distribution of PCDD/Fs and CBzs from two co-processing RDF cement plants in China
An analysis of the emission and distribution characteristics of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) and chlorobenzenes (CBzs) from two cement kilns (CK1 and CK2) is done. Six measurement...

Low temperature destruction of PCDD/Fs by catalysis coupled with activated carbon
In order to enhance the oxidation and adsorption capacity of catalyst, two kinds of activated carbon (AC) are mechanically mixed with V2O5-WO3/TiO2 catalyst respectively. In this study, the mixtures (M-1: catalys...
