More Information
Summary:The present disclosure relates to a method for forming a catalyst article comprising: (a) forming a plastic mixture having a solids content of greater than 50 % by weight by mixing together a crystalline small pore molecular sieve in an H+ or NH4+ form, iron sulphate, an inorganic matrix component, an organic auxiliary agent, an aqueous solvent and optionally inorganic fibres; (b) moulding the plastic mixture into a shaped article; and (c) calcining the shaped article to form a solid catalyst body. The present disclosure further relates to a catalyst article, an exhaust system, and a method of treating an exhaust gas.
