Nettet19. mai 2014 · Selective catalytic reduction employs chemical reduction to render nitrogen oxides harmless. The term Selective Catalytic Reduction (or SCR) is used to describe a chemical reaction in which harmful nitrogen oxides (NOX) in exhaust gas are converted into water (H2O) and nitrogen (N2). In combination with internal engine technologies, … Nettet21. nov. 2024 · In autocatalysis, the reaction is catalysed by one of its products. One of the simplest examples of this is in the oxidation of a solution of ethanedioic acid (oxalic acid) by an acidified solution of potassium manganate (VII) (potassium permanganate). The reaction is very slow at room temperature.
