Abstract:
This chapter discusses the effect of an organic plasticizer on the catalytic batch formation by extrusion and the catalytic properties of oxide compositions. Monolithic honeycomb catalysts are widely applied in the catalytic purification of exhaust gases containing ecologically harmful compounds. The purification degree of the gas flows in a contact layer at 250–350°C is 80–85%. The qualitative and quantitative composition of catalysts for the selective catalytic reduction (SCR) of nitrogen oxides with ammonia is often determined by the composition of a purified gas. By mixing oxides (or their precursors) with inorganic and organic plasticizers, the catalyst composition suitable for the extrusive formation in form of the honeycomb monolith of various geometries can be produced. Inorganic plasticizers give the required mechanical strength to the catalyst monoliths, whereas organic plasticizers impart the necessary rheological properties to the catalyst mass, which provide its successful extrusion. Plasticizers play an important role in the extrusive formation of the catalyst mass. They form a medium that allows the catalyst batch particles to move in respect to one another without deformation and collapsing.
