Abstract
A novel ternary Mn<sub>0.1</sub>Co<sub>0.9</sub>Cr<sub>2</sub>O<sub>4</sub> catalyst was identified from a range of chromium-based spinel-type oxides for the SCR of NO<italic>x</italic> in coking flue gas. The SCR reaction mainly occurs between the adsorbed NH<sub>3</sub> and the adsorbed nitrates, following the Langmuir–Hinshelwood mechanism.
