TL;DR: In this article, the CoNH4-beta and CoH-beta zeolites, with various Co loadings, were prepared by Co ion exchange into NH4- and H-beta parent Zeolite, from which the template was removed by calcination of the as-synthesized beta zeolite in a stream of ammonia and oxygen, respectively.

TL;DR: In this paper, a method of controlling a rate of introduction of a NOx reducing substance or precursor to a catalyst component is proposed, which is based on obtaining the amount of NOx entering the catalyst component and modelling the amount in the catalytic component.
Abstract: A method of controlling a rate of introduction of a NOx reducing substance or precursor to a catalyst component (1). The method comprises obtaining the amount of NOx entering the catalyst component (1), modelling the amount of NOx reducing substance or precursor in the catalyst component (1) and controlling the rate of introduction of the NOx reducing substance or precursor to reduce NOx.

TL;DR: In this article, the authors showed that migration of copper species from the surface region upon activation of Cu-SAPO-34 leads to a several-fold increase in catalytic activity for the selective catalytic reduction of NOx with NH3.
Abstract: Migration of copper species from the surface region upon activation of Cu–SAPO-34 leads to a several-fold increase in catalytic activity for the selective catalytic reduction of NOx with NH3. The temperatures required for the activation are higher than normal calcination temperatures and lead to a homogeneous transition metal distribution that renders Cu–SAPO-34 an industrially promising candidate for NOx removal.
