Theoretical and experimental study of the interaction between NOx reduction and SO2 oxidation over DeNOx-SCR catalysts

The interaction between NOx reduction and the undesired SO2 oxidation over DeNOx-SCR catalysts is investigated experimentally during catalyst conditioning and by transient and steady-state activity tests, as well as by means of model simulations in order to evaluate possible methods to minimize formation of SO3.

Influence of the process parameters on the extrusion of ceramic catalysts

Summary A systematic and quantitative study of the extrusion of Ti0 2 based ceramic pastes in the form of honeycomb is presented. The rheological properties of the paste are correlated to its extrudability and to the morphological and mechanical characteristics of the final compound. A mathematical model of the single screw extruder is developed for scale up purposes and validated against data.

Transient kinetics of SO2 oxidation over SCR-DeNO(x) monolith catalysts

A dynamic kinetic study of the undesired oxidation of SO2 over a commercial V2O5−WO3/TiO2 monolith catalyst for the SCR-DeNOx process is herein presented. Transient SO2 conversion data were systema...

On the Relations Between the Rheology of Tio2-Based Ceramic Pastes and the Morphological and Mechanical Properties of the Extruded Catalysts.

A rational and quantitative study of extrusion of TiO 2 -based ceramic pastes is attempted. First the analysis of rheological measurements, that are used to investigate and foresee the formability behaviour of the pastes, is illustrated. Then the mixing stage and two of the most relevant preparation parameters, namely liquid content and inorganic additives, are discussed to clarify the correlations between operative parameters, corresponding rheological characteristics of the paste, and morphological, structural and mechanical properties of the final material.
