Simulation of N2O abatement in waste gases by its decomposition over K-promoted Co-Mn-Al mixed oxide catalyst

摘要

Introduction In last years, the catalytic decomposition of N2O as a method for lowering N2O emissions in waste gases attracts increasing attention due to the expected inclusion of N2O in the greenhouse gas trade. Multicomponent mixed oxides prepared by thermal treatment of layered double hydroxide (LDH) precursors belong to the active and stable catalysts for the N2O decomposition [1]. This contribution deals with estimation of N2O abatement by using a catalytic reactor situated downstream of the DeNOx technology in nitric acid production unit.
