Abstract This work constructed a divided diaphragm seawater electrolysis system with two tandem packed towers for the synergistic removal of NOx and SO2. The first tower was mainly used to oxidize NO SO2 by AC (active chlorine), second further absorb NOx. factors affecting on removal, including ACC chlorine concentration), pH value, initial concentration temperature in oxidation were investigat...

Strict environmental regulations on air quality coupled with a consumer desire for more efficient engines has forced the automotive industry to start developing more advanced emissions aftertreatment technologies. Of the common diesel exhaust treatment methods for NOx removal, Lean NOx Traps (LNT) have been recognized as the most practical for use in small displacement engines. The current stat...

A series of copper oxide (CuOx) catalysts supported by oxidized multi-walled carbon nanotubes (OMWNT’s) were prepared by the wet impregnation method for the low temperature (200 °C) selective catalytic reduction of nitrogen oxides (NOx) using NH3 as a reductant agent in the presence of excess oxygen. These catalysts were characterized by FTIR, XRD, SEM-EDS, and H2-TPR meth...

Nitrogen oxides (NOx) released in atmosphere by fuels combustion lead to photochemical smog and acidic rains and have negative effects on human`s nervous system. In this research nanocomposite membranes of Poly Vinylidene Fluoride (PVDF)/ Poly Dimethylsiloxane (PDMS) and Titanium Dioxide nanoparticles (TiO2) with different weight percentage of TiO2 (0.5 and 1) for adsorption of NOx were prepare...
