TL;DR: A range of alumina-supported platinum catalysts have been prepared and investigated for the selective reduction of nitrogen monoxide in the presence of a large excess of oxygen in steady state microreactor experiments.

TL;DR: An electrooptical scanning device which can detect the relative position of register mark applied to a moving web, either serially on a single track or in two parallel, side-by-side tracks which extend in the direction of movement of the web is described in this article.

TL;DR: In this paper, a method of selectively catalyzing the reduction of NO x in an exhaust gas flowing in an internal combustion engine comprising a filter for particulate matter comprising a catalyst capable of selectively catalysing the reduction with a reducing agent was proposed.

TL;DR: In this paper, the activation of propene and nitric oxide by Cu/ZSM-5, in the presence and absence of oxygen, have been investigated by TAP to elucidate the nature of the reducing species involved in the formation of nitrogen.

TL;DR: In this article, two Diesel particulate matter emission control devices, the CCRT and the catalyzed continuously regenerating trap (CCRT), were evaluated using a mobile emissions laboratory.
