Texto completoIn the present work the NOx reduction with C3 hydrocarbons has been examined. The objective is to study the influence of SO2 on metal based catalysts with an oxygen excess in the presence of CO2 and H2O, in a temperature range from 200 to 400 °C. The NOx are totally converted under stoechiometric conditions in the absence of sulfur dioxide and the most sulfur resistant catalyst is Pt/ZrAl. A series of different metals (Pt, Pd, Rh, Ag, Ir, Sn ) supported on several oxides (Al, , K-Al, Ce-Al, Ti-Al, Zr-Al, Ce-Zr, Si, C) were tested for NOx reduction with 1000 ppm propylene and the Pt/ZrAl was found to be the most active catalyst. The sulfation of the catalysts, generally leads to an increase of their activity in the presence of SO2, and conversely to a decrease of the N2O selectivity. Finally, the NO consumption has been observed in both the presence and the absence of propane. This phenomenon has been associated with the nitric acid formation via NO oxidation and not with NOx reduction

Texto completoThe context of this study concerns the propene/propane separation, claimed as a technical and energetic challenge in the industry. The difficulty is mainly due to the strong similarity of the physical and chemical properties of the molecules involved. To address this issue, we have been interested in evaluating the adsorption performance towards these gases, in terms of capacity and selectivity of a range of porous materials (zeolites and ZIFs). To this end, a complete study, both on the thermodynamic and kinetic aspects, of the adsorption properties on type A zeolites, purely silicic and with different compensation cations and ZIFs-8, has been carried out by a specific adsorption microcalorimetry apparatus which allows to measure simultaneously the adsorption isotherms and the corresponding energies. Thus for the different porous materials; the affinity of the adsorbent for a gas and the selectivity by the IAST method were determined from the equilibrium adsorption isotherms of pure gases. Kinetic parameters were also calculated by application of the Crank and LDF model from the adsorption rate versus time curves. In the ZIF-8 family, it was found that the adsorption kinetics of the adsorbent molecules is mainly controlled by the pore opening size as well as its flexibility
