PROCESS FOR PRODUCTION OF AN EXTRUDED CATALYST, AND, CATALYST To be able to produce an SCR catalyst (2), in particular one that has a zeolite (Z) fraction as the catalytically active fraction, in a reliable process and at the same time achieve a good catalytic activity of the catalyst (2), an inorganic binder fraction (B) which is catalytically inactive in the starting state and which has been treated to develop catalytic activity is mixed into a catalyst composition (4). The inorganic binder component for the binder fraction (B) is, in the broken state, preferably of porous particles (10), in particular diatomite, which exhibits mesoporosity. To effect the catalytic activation, the individual particles (10) are either coated with a catalytically active layer (12) or transformed into a catalytically active zeolite (14) with the maintenance of mesoporosity. |
