Low-temperature selective catalytic reduction of NO with NH_3 over Ce-Mn/TiO_2 catalyst
TLDR
In this paper, the ability of low-temperature selective catalytic reduction (SCR) of NO with ammonia in the presence of excess O 2 and the effects of SO 2 and H 2 O were studied.Abstract:
Ce-Mn/TiO_ 2 catalyst was prepared by impregnation method. The ability of low-temperature selective catalytic reduction (SCR)_ of NO with ammonia in the presence of excess O_ 2 and the effects of SO_ 2 and H_ 2 O were studied. The experimental results showed that the reaction temperature, GHSV, NO import concentration and NH_ 3 / NO have slight effects on SCR activity. More than 95% of NO conversion was obtained over Ce-Mn/TiO_ 2 catalyst at 120℃. In addition, the catalyst showed very well ability to resist the deactivation of SO_ 2 and H_2 O.read more

The effects of manganese precursors on Mn-based/TiO2 catalysts for catalytic reduction of NO with NH3.
TL;DR: Different precursors could lead to different grain size of active components, manganese oxide dispersion, and surface phase state of Mn/TiO2 catalyst, whereas these influences are reduced with the doping of cerium oxides into Mn/ TiO2.

Evaluation of NOX Removal from Simulated Flue Gas by "Absorption-Oxidation-Reduction" Method
TL;DR: In this article, the authors presented a new method of absorption-oxidation-reduction which used ferrous sulfate solution as absorbent, oxygen as oxidizer and urea as reducer to remove NOX from flue gas based on the properties of Fe2+, NO, [Fe (NO)]2+ and Urea.
