Abstract
The invention relates to a method and a catalyst for removal of nitrogen oxides in a flue gas from a combustion engine or gas turbine by injecting a reducing agent and reducing the nitrogen oxides in the presence of a catalyst. The catalyst is a zeolite based catalyst on a corrugated monolithic substrate, the substrate has a density of 50-300 g/l and a porosity of at least 50%. The monolithic substrate is a paper of high silica content glass or a paper of E-glass fiber with a layer of diatomaceous earth or a layer of titania, and the catalyst is a Fe-β zeolite.
