Filter Elements Based on Aluminosilicate Fibers for Selective Catalytic Reduction of Nitrogen Oxides — a Review

Abstract

A literature review on oxide compositions developed to modify ceramic aluminosilicate fibers-based filter elements for the selective catalytic reduction of nitrogen oxides during the purification of high-temperature industrial gases is presented. Methods for preparing the catalytic compositions and methods for their introduction into the structure of the ceramic filter elements are also discussed.
